2006-07-16  Paul Eggert  <eggert@cs.ucla.edu>

        * dirchownmod.c, dirchownmod.h, mkancesdirs.c, mkancesdirs.h:
        New files.
        * mkdir-p.c: Don't include alloca.h, stdio.h, sys/types.h,
        unistd.h, string.h, chdir-safer.h, dirname.h, lchmod.h, lchown.h,
        save-cwd.h.  Instead, include dirchownmod.h and mkancesdirs.h.
        (make_dir_parents): New args MAKE_ANCESTOR, OPTIONS, ANNOUNCE,
        MODE_BITS.  Remove options VERBOSE_FMT_STRING, CWD_ERRNO.  All
        callers changed.  Revamp internals significantly, by not
        attempting to create directories that are temporarily more
        permissive than the final results.  Do not attempt to use
        save_cwd/restore_cwd; it isn't worth it for mkdir and install.
        This removes some race conditions, fixes some bugs, and simplifies
        things.  Use new dirchownmod function to do owner and mode changes.
        * mkdir-p.h: Likewise.
        * modechange.c (octal_to_mode): New function.
        (struct mode_change): New member mentioned.
        (make_node_op_equals): New arg mentioned.  All callers changed.
        (mode_compile): Keep track of which mode bits the user has explicitly
        mentioned.
        (mode_adjust): New arg DIR, so that we implement the X op correctly.
        New arg PMODE_BITS, to keep track of which mode bits the user
        mentioned; it treats S_ISUID and S_ISGID speciall.
        All callers changed.
        * modechange.h: Likewise.

2006-07-11  Derek R. Price  <derek@ximbiot.com>

        * glob.c: s/NAMLEN/_D_EXACT_NAMLEN/.

2006-07-10  Derek R. Price  <derek@ximbiot.com>

        * backupfile.c, dirfd.h, fts.c, getcwd.c, glob.c, glob_.h:
        Ignore the obsolescent !HAVE_DIRENT_H case.  Consolidate NAMLEN
        macros into the GNU _D_EXACT_NAMLEN.
        * savedir.c:  Likewise.
        (savedirstream): Use _D_EXACT_NAMLEN in preference to strlen.

2006-07-09  Jim Meyering  <jim@meyering.net>

        * argp-pv.c: Remove a doubled word in a comment.
        * check-version.c (check_version): Likewise.
        * javacomp.c (compile_java_class): Likewise.

2006-07-08  Jim Meyering  <jim@meyering.net>

        * getndelim2.h (getndelim2): Remove doubled "after" in comment.

2006-07-06  Jim Hyslop  <jhyslop@dreampossible.ca>  (tiny change)

        * lib/getaddrinfo.c: Changes to compile under MSVC6: changed
        '#if WIN32_NATIVE' to '#ifdef' & moved WSAAPI macro inside
        brackets.  Other minor changes to suppress some compiler
        warnings.

2006-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * getloadavg.c: Use __VMS, not VMS.
        * getopt.c: Likewise.
        * getpagesize.h: Likewise.
        * glob.c: Remove most VMS cruft; it hasn't been tested for a while and
        probably does not work.

2006-07-06  Derek R. Price  <derek@ximbiot.com>
        and Paul Eggert  <eggert@cs.ucla.edu>

        * backupfile.c [HAVE_DIRENT_H && ! HAVE_NDIR_H]:
        Don't worry about this obsolete case any more.
        (HAVE_DIR): Remove.  All uses removed; we now assume you can read
        directories.
        * dirfd.h [HAVE_DIRENT_H && ! HAVE_NDIR_H]: Don't
        worry about this obsolete case any more.
        * fts.c: Likewise.
        * getcwd.c: Likewise.
        * glob.h: Likewise.
        * savedir.c: Likewise.

2006-07-06  Paul Eggert  <eggert@cs.ucla.edu>

        * .cppi-disable: Add wcwidth.
        * fnmatch.c (ISBLANK): Remove.  All uses changed to isblank.
        (isblank) [! (defined isblank || HAVE_DECL_ISBLANK)]: New macro.
        (ISGRAPH): Remove.  All uses changed to isgraph.
        (FOLD) [!defined _LIBC]: Remove special case.
        * getdate.y (lookup_word): Remove no-longer-needed call to islower.
        * regext_internal.h (isblank): Depend on HAVE_DECL_ISBLANK, not
        HAVE_ISBLANK.
        * strftime.c (TOLOWER, TOUPPER) [!defined _LIBC]: Remove special case.

2006-07-06  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * strtod.c (strtod): cast the argument of tolower to unsigned char.

2006-07-05  Paul Eggert  <eggert@cs.ucla.edu>

        * memcasecmp.c: Include <limits.h>.
        (memcasecmp): Don't assume UCHAR_MAX <= INT_MAX.
        * strtod.c (strtod): Don't assume isspace works on negative chars.
        Don't assume isdigit succeeds only on '0' through '9'.

2006-07-05  Derek R. Price  <derek@ximbiot.com>

        * exclude.c (IN_CTYPE_DOMAIN, is_space): Remove; no longer needed.
        All uses of is_space replaced by isspace.
        * exit.h: Don't talk about STDC_HEADERS.
        * fnmatch.c (ISASCII): Remove; no longer needed.  All uses removed.
        (ISPRINT, ISDIGIT, ISALNUM, ISALPHA, ISCNTRL, ISLOWER, ISPUNCT):
        (ISSPACE, ISUPPER, ISXDIGIT): Remove; no longer needed.  All uses
        replaced by isprint etc.
        * getdate.y (IN_CTYPE_DOMAIN, ISSPACE, ISALPHA, ISLOWER): Likewise.
        * getusershell.c (IN_CTYPE_DOMAIN, ISSPACE): Likewise.
        * memcasecmp.c (IN_CTYPE_DOMAIN, ISLOWER, TOUPPER): Likewise.
        * strtod.c (IN_CTYPE_DOMAIN, ISSPACE, ISDIGIT, TOLOWER): Likewise.
        * strtol.c (IN_CTYPE_DOMAIN): Likewise.
        * xstrtol.c (IN_CTYPE_DOMAIN, ISSPACE): Likewise.

2006-07-05  Eric Blake  <ebb9@byu.net>

        * getaddrinfo.h (NI_NUMERICHOST, NI_NUMERICSERV): Define if
        missing from netdb.h.
        * getaddrinfo.c (includes): Include inet_ntop and snprintf.

2006-06-27  Bruno Haible  <bruno@clisp.org>

        Assume ANSI C header files and <ctype.h> functions.
        * mbswidth.c (IN_CTYPE_DOMAIN, ISPRINT, ISCNTRL): Remove macros.
        (mbsnwidth): Use isprint, iscntrl instead.

2006-07-03  Jim Meyering  <jim@meyering.net>

        * cycle-check.h (CYCLE_CHECK_REFLECT_CHDIR_UP): Abort if this
        macro is used before the first cycle_check call.

2006-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        * stdint_.h: Include <sys/types.h> after @FULL_PATH_STDINT_H@, for
        MacOS X 10.4.6.  Don't mention <sys/int_types.h>.  Problems
        reported by Mark D. Baushke, one in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00015.html>.

        Merge from coreutils.

        * .cppi-disable: Add stdint_.h.
        * .cvsignore: Add stdint.h.

        2006-06-30  Paul Eggert  <eggert@cs.ucla.edu>

        * xstrtod.c (XSTRTOD, DOUBLE): New macros, so that we can support
        both double and long double versions.
        (XSTRTOD): Renamed from xstrtod.  Use DOUBLE internally.
        * xstrtold.c: New file.
        * xstrtod.h (xstrtold): New decl.

        2006-05-22  Paul Eggert  <eggert@cs.ucla.edu>

        * filemode.c (setst): Remove.
        (strmode): Rewrite to avoid setst.  This makes the code shorter,
        (arguably) clearer, and the generated code is a bit smaller on my
        Debian GNU/Linux stable x86 host.

        2006-04-17  Paul Eggert  <eggert@cs.ucla.edu>

        * filemode.c: Include "filemode.h" first, to test the interface.
        Assume that filemode.h includes sys/types.h and sys/stat.h.
        (HAVE_ST_DM_MODE): New macro, moved here from ls.c.
        (ftypelet): Reorder to put common cases first, for efficiency.
        Add 'P', 'w'.  Remove 'M', since it's now the caller's responsibility
        to do 'M'.
        (strmode): Renamed from mode_string, and now stores 12 bytes instead
        of 10, for compatibility with FreeBSD.  All callers changed.
        (filemodestring): Now stores 12 bytes instead of 10, and sets file types
        that can't be deduced solely from st_mode.  First arg is now a const
        pointer.
        * filemode.h (HAVE_DECL_STRMODE): Include <string.h> for strmode.
        (strmode): Renamed from mode_string.
        (filemodestring): New decl.
        * stat-macros.h: Don't undef S_ISDOOR, since it's never buggy.
        (S_ISDOOR): Don't bother with S_IFDOOR, since that code is never needed.
        (S_ISPORT, S_ISWHT): New macros, if not already defined.

        2006-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * fsusage.c: Don't include <inttypes.h> or <stdint.h>, since
        fsusage.h now does that.  Include fsusage.h first, to test interface.
        Prefer statvfs if it works, since it's blessed by POSIX.  Attempt
        at most one method (the old code could have generated decls that
        didn't conform to C89, not that this was ever exercised).
        * fsusage.h: Include <inttypes.h> and <stdint.h> if they exist.

        2006-03-19  Jim Meyering  <jim@meyering.net>

        Work even in a chroot where d_ino values for entries in "/"
        don't match the stat.st_ino values for the same names.
        * getcwd.c (__getcwd): When no d_ino value matches the target inode
        number, iterate through all entries again, using lstat instead.
        Reported by Kenshi Muto in http://bugs.debian.org/355810, and by
        Zouhir Hafidi in https://bugzilla.redhat.com/bugzilla/190656.

        * getcwd.c (__getcwd): Clarify a comment.
        Use memcpy in place of a call to strcpy.

        2006-03-12  Jim Meyering  <jim@meyering.net>

        * fts-cycle.c (leave_dir): If cycle-check's saved dev-ino pair matches
        that of the current directory (which we're about to chdir ".." out of),
        then save the dev-ino of the parent, instead.

        * same-inode.h (SAME_INODE): New file/macro.
        * chdir-safer.c (SAME_INODE): Remove definition.
        Include "same-inode.h", instead.
        * same.c: Likewise.
        * cycle-check.h: Include "same-inode.h".
        (CYCLE_CHECK_REFLECT_CHDIR_UP): Define.
        * cycle-check.c (SAME_INODE): Remove definition.
        * root-dev-ino.h: Include "same-inode.h".

        2006-03-11  Eric Blake  <ebb9@byu.net>

        * same.c (same_name): s/base_name/last_component/
        * backupfile.c (check_extension, numbered_backup): Likewise.
        * filenamecat.c (file_name_concat): Likewise.

        2006-03-11  Eric Blake  <ebb9@byu.net>,
                    Paul Eggert  <eggert@cs.ucla.edu>

        * dirname.h (FILE_SYSTEM_PREFIX_LEN): Move here from dos.m4.
        [FILE_SYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]: Don't treat 1: as a
        drive prefix.
        (IS_ABSOLUTE_FILE_NAME): Treat all drive letters as absolute on
        platforms like cygwin with FILE_SYSTEM_DRIVE_PREFIX_IS_ABSOLUTE.
        (last_component): New method.
        * dirname.c (dir_len): Determine when drive letters need a
        subsequent slash.  Preserve // when it is special.
        (dir_name): Don't append dot when drive letter is absolute.
        [TEST_DIRNAME]: Move into a full-blown gnulib test.
        * basename.c (base_name): New semantics - malloc the result.
        Preserve // when it is special.  Preserve relative files that look
        like drive letters.
        (base_len): Preserve // when it is special.
        (last_component): New method, similar to old base_name semantics.
        * stripslash.c (strip_trailing_slashes): Use last_component, not
        base_name.  Strip redundant slashes from ///.

2006-07-02  Paul Eggert  <eggert@cs.ucla.edu>

        * stdint_.h (intmax_t, uintmax_t): Prefer long to long long if
        both are 64 bits, since this seems to be the tradition, and this
        prevents gcc -Wformat from warning about usages with PRIuMAX.  If
        we ever run into a host that prefers long long to long in this
        case, we'll need another configure-time test.  Problem reported by
        Jim Meyering.

2006-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * stdint_.h (_GL_STDINT_H): Renamed from _STDINT_H, to avoid
        possible collision with system files.
        (<stdio.h>, <time.h>, <wchar.h>) [defined __cplusplus && ! defined
        __STDC_CONSTANT_MACROS)]: Do not include, since we don't need
        WCHAR_MIN and WCHAR_MAX in this case.
        (<stddef.h>): Do not include; no longer needed.
        (<sys/types.h>): Include if @HAVE_SYS_TYPES_H@, not if
        (defined(__OpenBSD__) || defined(__bsdi__) || defined(__sgi)).
        (<sys/inttypes.h>): Include if @HAVE_SYS_INTTYPES_H@ &&
        !@HAVE_INTTYPES_H@, not if (defined(__FreeBSD__)
        && (__FreeBSD__ >= 3) && (__FreeBSD__ <= 4)).
        (__STDINT_H__) [@HAVE_STDINT_H@ && defined __sgi && ! defined
        __c99]: Define, to work around IRIX <stdint.h> incompatibility.
        (@FULL_PATH_STDINT_H@) [!(defined(__sgi) && @HAVE_INTTYPES_H@ &&
        !defined(__c99))]: Include in this case too, since it's harmless
        now.
        (<inttypes.h>) [@HAVE_INTTYPES_H@]: Include, since it's no longer
        dangerous to do so.
        (@FULL_PATH_INTTYPES_H@) [(defined(__hpux) || defined(_AIX)) &&
        @HAVE_INTTYPES_H@]: Do not include, since we now include <inttypes.h>.
        (_STDINT_MIN, _STDINT_MAX): New macros.
        (int8_t, uint8_t, int16_t, uint16_t, int32_t, uint32_t, int64_t):
        (uint64_t, int_least8_t, uint_least8_t, int_least16_t):
        (uint_least16_t, int_least32_t, uint_least32_t, int_least64_t):
        (uint_least64_t, int_fast8_t, uint_fast8_t, int_fast16_t):
        (uint_fast16_t, int_fast32_t, uint_fast32_t, int_fast64_t):
        (uint_fast64_t, intptr_t, uintptr_t, intmax_t, uintmax_t): Now
        macros, not typedefs; this simplifies things quite a bit.
        Use long int for all types narrower than int64_t.
        (intmax_t, uintmax_t, INTMAX_C, UINTMAX_C):
        Define in terms of long long int or int64_t or long int,
        not int64_t or int32_t.  This saves some compile-time testing.
        (INT8_MIN, INT8_MAX, UINT8_MAX, INT16_MIN, INT16_MAX, UINT16_MAX):
        (INT32_MIN, INT32_MAX, UINT32_MAX, INT64_MIN, INT64_MAX):
        (UINT64_MAX, INT_LEAST8_MIN, INT_LEAST8_MAX, UINT_LEAST8_MAX):
        (INT_LEAST16_MIN, INT_LEAST16_MAX, UINT_LEAST16_MAX):
        (INT_LEAST32_MIN, INT_LEAST32_MAX, UINT_LEAST32_MAX):
        (INT_LEAST64_MIN, INT_LEAST64_MAX, UINT_LEAST64_MAX, INT_FAST8_MIN):
        (INT_FAST8_MAX, UINT_FAST8_MAX, INT_FAST16_MIN, INT_FAST16_MAX):
        (UINT_FAST16_MAX, INT_FAST32_MIN, INT_FAST32_MAX, UINT_FAST32_MAX):
        (INT_FAST64_MIN, INT_FAST64_MAX, UINT_FAST64_MAX, INTPTR_MIN):
        (INTPTR_MAX, UINTPTR_MAX, INTMAX_MIN, INTMAX_MAX, UINTMAX_MAX):
        (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
        (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
        undef any previous version and define our own version, for
        simplicity and consistency with the new macros for types.
        (PTRDIFF_MIN, PTRDIFF_MAX, SIG_ATOMIC_MIN, SIG_ATOMIC_MAX):
        (SIZE_MAX, WCHAR_MIN, WCHAR_MAX, WINT_MIN, WINT_MAX):
        Simplify definitions by using _STDINT_MIN and _STDINT_MAX
        where appropriate.  Rely on new symbols @PTRDIFF_T_SUFFIX@,
        @SIG_ATOMIC_T_SUFFIX@, @SIZE_T_SUFFIX@, @WCHAR_T_SUFFIX@,
        @WINT_T_SUFFIX@ to keep things simple here.
        (UINT8_C, UINT16_C, UINT32_C, INT64_C, UINT64_C):
        Simplify by assuming typical 8/16/32/64 host, since we're
        already doing that elsewhere anyway.
        Use (LONG_MAX >> 31 >> 31 == 1) rather than @HAVE_LONG_64BIT@,
        and assume long long int is 64 bits if available.  This
        speeds up 'configure'.

2006-06-30  Jim Hyslop <jhyslop@dreampossible.ca>  (tiny change)

        * getaddrinfo.c: fixed typo

2006-06-29  Eric Blake  <ebb9@byu.net>

        unused static function.

2006-06-29  Eric Blake  <ebb9@byu.net>

        * stat_.h: New file.

2006-06-29  Derek R. Price  <derek@ximbiot.com>

2006-04-09  Paul Eggert  <eggert@cs.ucla.edu>

        Merge regex changes from libc, removing some of our
        POSIX-conformance changes that were rejected and redoing them in a
        less-intrusive way.

        * regcomp.c (re_compile_internal, init_dfa):
        Length arg is now size_t, not Idx.  All uses changed.
        (peek_token): Forward decl now says internal_function.
        (__re_error_msgid, __re_error_msgid_idx):
        Now static rather than extern with attribute_hidden.
        (re_compile_pattern) [!defined _LIBC]: Use K&R-style defn.
        For some reason libc prefers K&R style defns for external functions.
        (regerror) [!defined _LIBC]: Likewise.
        (re_set_syntax, re_compile_fastmap, regcomp, regfree, re_comp):
        (seek_collating_symbol_entry, lookup_collation_sequence_value):
        (build_range_exp, build_collating_symbol):
        Use K&R-style defn.

        (build_range_exp, build_collating_symbol):
        Now internal functions.

        * regex.c [!defined _LIBC]: Allow compiling with C++ compilers.

        * regex.h (__USE_GNU_REGEX): New macro.  Don't depend on
        _REGEX_SOURCE any more; depend on _GNU_SOURCE instead.
        Don't depend on VMS; depend on __VMS instead, for POSIX
        namespace cleanness.
        (regoff_t): Define to ssize_t, not long int.

        Remove the REG_ macros named below.  Instead, make the old names
        (e.g., RE_BACKSLASH_ESCAPE_IN_LISTS) visible only if
        __USE_GNU_REGEX.
        (REG_BACKSLASH_ESCAPE_IN_LISTS):
        (REG_BK_PLUS_QM, REG_CHAR_CLASSES, REG_CONTEXT_INDEP_ANCHORS):

        (REG_DUP_MAX, REG_UNALLOCATED, REG_REALLOCATE, REG_FIXED):

        (RE_INTERVALS, RE_LIMITED_OPS, RE_NEWLINE_ALT):
        (RE_NO_BK_BRACES, RE_NO_BK_PARENS, RE_NO_BK_REFS):
        (RE_NO_BK_VBAR, RE_NO_EMPTY_RANGES):
        (RE_UNMATCHED_RIGHT_PAREN_ORD, RE_NO_POSIX_BACKTRACKING):
        (RE_NO_GNU_OPS, RE_DEBUG, RE_INVALID_INTERVAL_ORD):
        (RE_IGNORE_CASE, RE_CARET_ANCHORS_HERE):
        (RE_CONTEXT_INVALID_DUP, RE_NO_SUB):
        Don't bother having these macros be independent of each others'
        values, since they no longer exist in the POSIX name space.

        Rename the following member names back to their old names,
        unless !__USE_GNU_REGEX.  All uses changed back.

        (re_xmalloc, re_calloc, re_xrealloc, re_x2realloc): Remove.

        (re_x2nrealloc): Remove.

2006-03-24  Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

        * base64.c (base64_encode): Do not read past end of array with
        unsanitized input on systems with CHAR_BIT > 8.

2006-03-16  Paul Eggert  <eggert@cs.ucla.edu>

        * regex.h (regoff_t) [defined _REGEX_LARGE_OFFSETS]:
        Typedef to long int, not to off_, as POSIX will likely change
        in that direction.

2006-03-13  Sergey Poznyakoff  <gray@gnu.org.ua>

2006-03-11  Paul Eggert  <eggert@cs.ucla.edu>

        * time_r.h (asctime_r, ctime_r): Remove.  These functions can

        * glob.c: Say "invalid" rather than "illegal" in comments.

2006-02-24  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        * getcwd.c (AT_FDCWD): Work around a bug in Solaris 9 and 10, where
        AT_FDCWD exceeds INT_MAX.

2006-02-14  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        Eliminate the unwelcome (albeit unlikely) possibility of xmalloc
        failure on deficient systems, and simplify gnulib lgpl dependencies.
        * lstat.c (rpl_lstat): Rewrite to use stat() in place of the
        xmalloc/lstat combination.  Based on a patch from Bruno Haible.

        * xalloc-die.c: Remove unused definition of N_.

2006-02-13  Sergey Poznyakoff  <gray@gnu.org.ua>

        * argp-fmtstream.c: Restore another bugfix lost on 2005-12-12

2006-02-07  Paul Eggert  <eggert@cs.ucla.edu>

        * closeout.c (close_stdout): Don't assume 'bool' converts nonzero
        ints to 0 or 1, as this isn't true for the stdbool.h substitute.

2006-02-07  Sergey Poznyakoff  <gray@gnu.org.ua>

        * argp-namefrob.h: Restore changes accidentally lost during the
        "autoupdate" on 2005-12-12.

2006-01-27  Paul Eggert  <eggert@cs.ucla.edu>

        * fnmatch.c (L_): Renamed from L, to work around a bug in
        Mac OS X 10.3.9 with GCC 3 reported by Claudio Fontana in
        <http://lists.gnu.org/archive/html/bug-gnulib/2006-01/msg00074.html>.
        All uses changed.

2006-01-26  Simon Josefsson  <jas@extundo.com>

        * socket_.h: Set WINVER to 0x0501, to make sure getaddrinfo
        prototype is visible on mingw32.

        * getaddrinfo.h: Define EAI_ADDRFAMILY and EAI_SYSTEM if not set,
        for mingw32.

        * gai_strerror.c, getaddrinfo.h: Protect netdb.h #include (for
        mingw32).

2006-01-26  Paul Eggert  <eggert@cs.ucla.edu>

        * fts.c (diropen): Open with O_NOCTTY | O_NONBLOCK too.  Don't
        attempt to open for write; this always fails, at least on POSIX
        hosts.  This reinstates the 2006-01-09 change, which was
        inadvertently removed.

2006-01-26  Bruno Haible  <bruno@clisp.org>
            Paul Eggert  <eggert@cs.ucla.edu>

        * stdbool_.h (_Bool)
        [(! (defined __cplusplus || defined __BEOS__)
          && !defined __GNUC__
          && !(defined __HP_cc || defined __xlc__
               || (defined __SUNPRO_C && (__SUNPRO_C < 0x550 || __STDC__ == 1))
               || defined __sgi))]:
        #define to signed char in these cases too; this simplifies
        the code (so that we don't have to worry about HP-UX, AIX, SunPRO,
        etc., separately) and makes it more conservative.

2006-01-21  Jim Meyering  <jim@meyering.net>

        Sync from the stable (b5) branch of coreutils:

        * fts.c (fts_children): Don't let close() clobber errno from
        failed fchdir().

        * fts.c (fts_stat): When following a symlink-to-directory,
        don't necessarily interpret stat-fails+lstat-succeeds as indicating
        a dangling symlink.  That can also happen at least for ELOOP.
        The fix: return FTS_SLNONE only when the stat errno is ENOENT.
        FYI, this bug predates the inclusion of fts.c in coreutils.

        * fts.c (fts_open): Put new maxarglen declaration and uses
        in their own block, so pre-c99 compilers don't object.

        Avoid the double-free (first in fts_read, second in fts_close) that
        would occur when an `active' directory is made inaccessible (e.g.,
        via chmod a-x) during a traversal.
        * fts.c (fts_read): After a failed fchdir, update sp->fts_cur
        before returning.  Reproduce this failure by
        mkdir -p a/b; cd a; chmod a-x . b
        Reported by Stavros Passas.

2006-01-24  Bruno Haible  <bruno@clisp.org>

        * stdbool_.h (_Bool) [__cplusplus]: Don't define if the compiler already
        has it.
        Report and patch by Albert Chin-A-Young  <china@thewrittenword.com> on
        2005-11-26.

        * stdbool_.h (_Bool) [HP-UX cc, AIX cc,xlc]: Define as 'signed char'
        to avoid problems with the built-in _Bool type.
        Reported by Paul Eggert on 2005-11-26.

2006-01-24  Jim Meyering  <jim@meyering.net>

2006-01-24  Simon Josefsson  <jas@extundo.com>

        * socket_.h (SHUT_WR, SHUT_RDWR): Don't hardcode, suggested by
        Bruno.

2006-01-23  Paul Eggert  <eggert@cs.ucla.edu>

        Work around porting bugs reported by Dieter in
        <http://lists.gnu.org/archive/html/bug-bison/2006-01/msg00049.html>.
        * getopt.c (_NOPROTO): Remove; no longer needed.
        Include <stdlib.h> and <unistd.h> in all environments; it's safe now.
        Include "getopt.h" first, to check interface.
        (getenv): Declare only if defined HAVE_DECL_GETENV &&
        !HAVE_DECL_GETENV.
        * strndup.c [!_LIBC]: Include "strndup.h" to get prototype.
        (__strndup): Revert to K&R-style function dfns, the glibc style.
        * strnlen.c: Don't claim it's taken from glibc; it's not.
        (strnlen, __strnlen): Remove #defines and #undefs; not needed.
        Include strnlen.h first, to get prototype properly.
        (strnlen): Renamed from __strnlen.
        Remove weak alias.

2006-01-23  Ulrich Drepper  <drepper@redhat.com>

        These changes imported from libc.
        * getopt.c: Use __fxprintf instead of inline stream orientation
        test and two separate function calls.
        * strndup.c (__strndup): Add libc_hidden_def.

2006-01-22  Bruno Haible  <bruno@clisp.org>

        * vasnprintf.c (VASNPRINTF): In the computation of the size of the
        temporary buffer for sprintf, take into account the precision also
        for 'd', 'i', 'u', 'o', 'x', 'X'.

2006-01-22  Paul Eggert  <eggert@cs.ucla.edu>

        * quotearg.c (quotearg_buffer_restyled): Add "default: break;"
        to pacify gcc -Wswitch-default.

2006-01-21  Sergey Poznyakoff  <gray@gnu.org.ua>

        * argp-help.c (usage_long_opt): Do not print DOC options.

2006-01-11  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * md5.c: Fix commentary typos.
        (alignof, UNALIGNED_P): No need for a GCC-specific version.
        * md5.h (__attribute__): Remove; unused.
        * sha1.c: Fix commentary to match md5 better.
        * sha1.h (struct sha1_ctx): Use a word buffer, not a byte buffer,
        so that we don't need to worry about alignment.  All uses changed.
        This merges the 2005-10-28 md5 change into sha1.

2006-01-11  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.
        * md5.c (OP): Fix spacing.

2006-01-10  Paul Eggert  <eggert@cs.ucla.edu>

        * regex_internal.h (BITSET_WORD_BITS):
        Work around a bug in 64-bit PGC (before version 6.1-2), where the
        preprocessor mishandles large unsigned values as if they were signed.
        Problem reported by Claudio Fontana in
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-12/msg00061.html>.

2006-01-10  Simon Josefsson  <jas@extundo.com>

        * localcharset.c: Update from GNU gettext.

2006-01-09  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.
        * chdir-long.c (cdb_free): Don't bother trying to open directory
        for write access: POSIX says that must fail.
        * fts.c (diropen): Likewise.
        * save-cwd.c (save_cwd): Likewise.
        * chdir-long.c (cdb_free): Open with O_NOCTTY | O_NONBLOCK as
        well, for minor improvements on hosts that lack O_DIRECTORY.
        * chown.c (rpl_chown) [CHOWN_MODIFIES_SYMLINK]:
        Don't try O_WRONLY unless O_RDONLY failed wth EACCES.
        Fall back on chown if open failed with EACCES.

        * gettime.c (gettime) [!defined OK_TO_USE_1S_CLOCK]:
        Report an error at compile-time if only a 1-second nominal clock
        resolution is found.

        * lchmod.h: New file.
        * mkdir-p.c: Include lchmod.h, lchown.h.
        (make_dir_parents): Use lchown rather than chown, and
        lchmod rather than chmod.

        * mountlist.c (ME_DUMMY): "none" and "proc" file systems are dummies
        too.  Problem with "none" reported by Bob Proulx.  Problem with
        "proc" reported by n0dalus.

        * mountlist.c: Include <limits.h>.
        (dev_from_mount_options)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]:
        New function.  It no longer assumes "dev=" has the System V meaning
        on Linux (since it doesn't).  It also parses "dev=" more carefully.
        (read_file_system_list)
        [defined MOUNTED_GETMNTENT1 || defined MOUNTED_GETMNTENT2]: Use it.
        MOUNTED_GETMNTENT2 is new here; the code didn't used to look for
        dev= in that case.

        * posixtm.h (PDS_PRE_2000): New macro.
        * posixtm.c (year): Arg is now syntax_bits rather than allow_century.
        All usages changed.  Reject dates outside the range 1969-1999 if
        PDS_PRE_2000 is used.

2006-01-09  Jim Meyering  <jim@meyering.net>

        * modechange.c (mode_compile): Reject an invalid mode string
        that starts with an octal digit.  From Andreas Gruenbacher.

        * openat.c: Include "fcntl--.h" and "unistd--.h", to map open
        and dup to open_safer and dup_safer, respectively.
        (openat_permissive): Fix typo in comment.

        * openat.c: Don't include <stdlib.h>, <unistd.h>, <fcntl.h>,
        "gettext.h"; either no longer needed or are guaranteed by openat.h.
        (_): Remove; no longer needed.
        (openat): Renamed from rpl_openat; no need for rpl_openat
        since openat.h renames openat for us.
        Replace most of the body with a call to openat_permissive,
        to avoid duplicate code.
        Port to (probably hypothetical) environments were mode_t is
        wider than int.
        (openat_permissive): Require mode arg, so that we can check
        types better.  Put it just after flags.  Change cwd failure
        indicator from pointer-to-bool to pointer-to-errno-value.
        All callers changed.
        Invoke openat_save_fail and/or openat_restore_fail if
        cwd_errno is null, so that openat can call us.
        (openat_permissive, fdopendir, fstatat, unlinkat):
        Simplify errno handling to avoid some duplicate code,
        as it's OK to set errno on success.
        * openat.h: Revamp code so that function macros depend on
        __OPENAT_PREFIX only, not also on AT_FDCWD.
        (openat_ro): Remove.  Caller changed to use openat_permissive.
        (openat_permissive): Now a macro, if not a function.
        (openat_restore_fail, openat_save_fail): Now always functions,
        since mkdirat needs them even if __OPENAT_PREFIX is defined.

        was an actual failure.
        Use EXPECTED_ERRNO rather than comparing against only ENOTDIR.

        Emulate openat-family functions using Linux's procfs, if possible.
        Idea and some code based on Ulrich Drepper's glibc changes.

        * openat.c: (BUILD_PROC_NAME): New macro.

        (rpl_openat): Emulate by trying to open /proc/self/fd/%d/%s,
        before falling back on save_cwd and restore_cwd.

        as second argument to va_arg.  Otherwise, some versions of gcc

        Remove AT_FDCWD test.
        Do not consume the fd unless successful.
        * openat.h (fdopendir): Do not define if HAVE_FDOPENDIR.
        * settime.c (settime): Move the HAVE_STIME block `up' into an #elif
        block, so that we don't even try to compile it if settimeofday is
        available.  This works around a compilation failure on OSF1 V5.1,
        due to stime requiring a `long int*' while tv_sec is `int'.

2005-09-30  Eric Blake  <ebb9@byu.net>  (tiny change)

        * getdelim.c (getdelim): Remove unused variables.

2005-10-01  Simon Josefsson  <jas@extundo.com>

        * getaddrinfo.h: Protect #include's of sys/socket.h and netdb.h.
        Only define struct addrinfo if !HAVE_STRUCT_ADDRINFO.  Protect
        AI_* and EAI_* definitions.  Protect function declarations.

2005-09-29  Paul Eggert  <eggert@cs.ucla.edu>

        * xtime.h (XTIME_PRECISION): Now of type int, not long long int,
        so that the code works even with ancient cpp.  Portability problem
        with GCC 2.7.2.1 reported by Thomas M.Ott.

2005-09-27  Jim Meyering  <jim@meyering.net>

        * getcwd.c: Change #ifdef<TAB>HAVE_CONFIG_H to #ifdef HAVE_CONFIG_H.

        * intprops.h (signed_type_or_expr__): Define.
        (INT_STRLEN_BOUND) [__GNUC__]: Use a slightly tighter bound
        for unsigned types.

2005-09-26  Paul Eggert  <eggert@cs.ucla.edu>

        * verify.h (verify_expr): Remove, replacing with:
        (verify_true): New macro that returns true instead of void.
        (verify_type__): Remove.
        (verify): Use verify_true rather than verify_type__.

2005-09-24  Paul Eggert  <eggert@cs.ucla.edu>

        * utimens.c (ENOSYS): Define if not already defined.
        (futimens): Support having a null PATH if the file descriptor
        is nonnegative.

        * regex_internal.h (__GNUC_PREREQ, always_inline, inline, pure):
        Remove.
        (__attribute): Define to empty unless GCC 3.1 or later.
        This works around a core dump on OpenBSD 3.4, which has GCC
        2.95.3, which dumps core when given __attribute__(()).  It also
        simplifies other tests, since we really don't want to bother with
        worrying about which ancient version of GCC supported what.
        Original problem reported by Yoann Vandoorselaere, with part of
        the fix suggested by Derek Price.

2005-09-24  Jim Meyering  <jim@meyering.net>

        * verify.h (verify_type__): Use `unsigned int' as the bitfield type
        so we can once again use a positive bitfield width of 1 -- now we
        don't have to explain why we were using a bitfield width of 2.

2005-09-23  Paul Eggert  <eggert@cs.ucla.edu>

        * getaddrinfo.c [HAVE_NETINET_IN_H]: Include <netinet/in.h>.
        Problem reported by Eric Blake.
        (getaddrinfo): Initialize se so that it's not garbage.
        Redo internal storage allocation so that it doesn't make unportable
        assumptions about alignment.
        Fix a memory leak.

        * utimens.c (futimens): Use futimesat if available.
        Prefer it to futimes since it doesn't have the futimes bug.

        * verify.h (GL_CONCAT0, GL_CONCAT): Remove.
        (verify): Don't use the __LINE__ trick, as it doesn't work in general.
        Instead, declare a function that returns a pointer to an array,
        and use verify_type__ to declare the size of the array.
        Problem and germ of a solution reported by Bruno Haible.
        (verify_type__): Use 2, not 1, for bitfield size, to avoid
        a warning with Irix 6.5 cc.  Problem reported by Bruno Haible.

2005-09-22  Paul Eggert  <eggert@cs.ucla.edu>

        Sync from coreutils.

        * .cppi-disable: Add regcomp.c, regex_internal.c, regex_internal.h,
        stat-time.h.
        * argmatch.h: Include verify.h
        (ARGMATCH_VERIFY): Use verify rather than rolling our own.
        (ARGMATCH_ASSERT): Remove; unused.
        * canonicalize.c: Assume STDC_HEADERS.
        * exclude.c: Include "strcase.h".
        * regex_internal.h [!defined _LIBC]: Likewise.
        * getusershell.c: Include stdio--.h rather than stdio.h
        and stdio-safer.h.
        (getusershell): Call fopen, not fopen_safer.
        * save-cwd.c: Include fcntl--.h rather than fcntl.h.
        Do not include unistd-safer.h.
        (save_cwd): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * getdate.y (relative_time): New type.
        (RELATIVE_TIME_0): New constant.
        (parser_control): Use relative_time instead of doing it ourselves.
        (%union): Add new relative_time rel member.
        (tYEAR_UNIT, tMONTH_UNIT, tHOUR_UNIT, tMINUTE_UNIT, tSEC_UNIT):
        Now typeless.
        (relunit, relunit_snumber): Now of type rel.
        (zone, rel, relunit, get_date): Adjust to above changes.

        * getloadavg.c: Include fcntl--.h rather than fcntl.h.
        Do not include unistd-safer.h.
        (getloadavg): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * mkdir-p.c (ENOSYS): Define to EEXIST if not defined.
        (make_dir_parents): Treat ENOSYS like EEXIST.

        Improve quality of diagnostics on restore_cwd failure.
        * mkdir-p.h (make_dir): Remove.  All uses replaced by mkdir.
        (make_dir_parents): Last arg is now int * (for errno), not bool *.
        * mkdir-p.c (make_dir, make_dir_parents): Likewise.
        Rewrite "mkdir -p" algorithm to avoid the need for "stat"
        each time through the loop.  Do not diagnose restore_cwd failure;
        that is the caller's job (and perhaps the caller does not care).

        * mkdir-p.c (CLEANUP_CWD, CLEANUP): Remove.
        (make_dir_parents): Revamp to avoid need for CLEANUP_CWD, CLEANUP.
        If the file already exists but is not a directory, don't bother
        to try to make its parents.
        Close potential file descriptor leak if we can't chdir("/") (!).
        Don't always return true if chdir($PWD) fails; return true only
        if the requested action was done successfully (except for the
        chdir($PWD)).
        Don't log final directory unless we actually made it.
        Refactor to avoid duplicate code to fix up permissions.
        Don't attempt to fix up parent permissions if chdir($PWD) fails.

        * strftime.c (my_strftime): Rewrite the previous change slightly,
        to make it a bit faster and (I hope) clearer.
        * strftime.c (my_strftime): Add support for %:z, %::z, %:::z.
        Fix bug in formats like %2N.

        * verify.h: New file.

2005-09-22  Jim Meyering  <jim@meyering.net>

        Sync from coreutils.

        * backupfile.c: Use ARGMATCH_VERIFY, just in case.

        * posixtm.c (posixtime) [lint]: Initialize *all* of tm0, not just
        the .tm_year member, since otherwise gcc-4.0 would now warn about
        tm_zone, tm_gmtoff, tm_isdst, tm_yday, tm_wday.

        * quotearg.c (quotearg_n_options): Change code to be suboptimal, in
        order to avoid an unsuppressible warning from gcc on 64-bit systems.

        * getdate.y (get_date): Undo part of the 2005-04-04 change, so that
        the command "date -d'2005-03-27 +1 day'" succeeds once again, even
        when run in a time zone for which daylight savings time is in effect
        for the starting date.

        * mkdir-p.c (make_dir_parents): Don't let a failed chdir($PWD)
        stop us from restricting permissions of just-created absolute-named
        directories.
        * mkdir-p.c (CLEANUP_CWD): Return *true*, not false when failing
        to restore initial working directory.
        * mkdir-p.c (make_dir_parents): New parameter: different_working_dir,
        to tell caller if/when we change the working directory and are
        unable to return to the initial one.
        * mkdir-p.h (make_dir_parents): Update prototype.
        * mkdir-p.c (CLEANUP_CWD): Change one more `return 1' to
        `return false'.  This fixes a bug introduced on 2004-07-30.

        * openat.c (fdopendir): Be sure to close the supplied
        file descriptor before returning.  This makes our replacement
        implementation a little closer to Solaris's, where fdopendir
        ties the file descriptor to the returned DIR* pointer.
        * openat.c (unlinkat): New function.
        * openat.h (unlinkat): Add prototype.
        * openat-die.c (openat_save_fail): Rename from openat_save_die.
        (openat_restore_fail): Rename from openat_restore_die.
        * openat.c, openat.h: Reflect s/_die/_fail/ renaming.

        Provide an alternative to exiting immediately upon save_cwd or
        restore_cwd failure.  Now, an application can arrange e.g.,
        to perform a longjump in that case.
        * openat.c: Include dirname.h.
        Use IS_ABSOLUTE_FILE_NAME rather than testing for leading slash.
        (rpl_openat, fdopendir, fstatat): Call openat_save_die
        and openat_restore_die rather than calling error directly.
        Don't include "error.h" or "exitfail.h"; they're no longer needed.

        * openat-die.c (openat_save_die, openat_restore_die): New file.
        * openat.h (openat_save_die, openat_restore_die): Declare and define.

        * strftime.c [FPRINTFTIME] (fprintftime): Provide a new interface:
        size_t fprintftime (FILE *fp, char const *fmt, struct tm const *tm,
                            int utc, int nanoseconds);
        Background:
        date should not have to allocate a megabyte of virtual memory to
        handle a format argument like +%1048575T.  When implemented with
        strftime, it must allocate such a buffer, use strftime to fill it
        in, print it, then free it.
        With fprintftime, it simply prints everything and exits.
        With no need for memory allocation, that's one fewer way to fail.
        * strftime.c (my_strftime): Parse the colons of %:::z *after* the
        optional field width, not before, so we accept %9:z, not %:9z.
        (my_strftime): Be sure to use L_('x') for literals.

        * backupfile.c, canon-host.c, canonicalize.c, chown.c, cloexec.c:
        * dup-safer.c, dup2.c, euidaccess.c, fd-safer.c, fileblocks.c:

        * save-cwd.c, setenv.c, settime.c, tempname.c, unlinkdir.c:
        * unsetenv.c, userspec.c, xgethostname.c, xreadlink.c:
        Assume HAVE_UNISTD_H, i.e., include <unistd.h> unconditionally.

        * chown.c, cloexec.c, dup-safer.c, dup2.c, fsusage.c, getcwd.c:
        * getloadavg.c, mountlist.c, openat.h, save-cwd.c, tempname.c:
        Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally,
        and don't include <sys/file.h>).

2005-09-22  Eric Blake  <ebb9@byu.net>  (tiny change)

        Sync from coreutils.

        * getloadavg.c (getloadavg) [__CYGWIN__]: Port to cygwin.
        [__linux__]: Allocate a big enough buffer for /proc/loadavg.
        [!LDAV_DONE]: Avoid unused variable warning.

2005-09-21  Bruno Haible  <bruno@clisp.org>

        * unicodeio.h (unicode_to_mb): New declaration.

2005-09-20  Derek Price  <derek@ximbiot.com>

        * getaddrinfo.c: Don't include <netdb.h> included from getaddrinfo.h.

2005-09-19  Ralf Wildenhues  <Ralf.Wildenhues@gmx.de>

        Use a consistent style for including <config.h>.

        in a different way.
        (timespec_cmp): New function.
        * utimecmp.c: Include stat-time.h.
        (SYSCALL_RESOLUTION): Depend on whether various struct stat
        members exist, not on the obsolescent ST_MTIM_NSEC.

        * getaddrinfo.c: Move include of getaddrinfo.h first to test interface.

        * glob-libc.h: Renamed from glob_.h.  The new version is
        taken from libc's glob.h, except with '#ifdef __GLOB_GNULIB'
        protecting things that should be done only in gnulib contexts.
        * glob_.h: New file, containing only the glob things needed for
        gnulib.
        (GLOB_PREFIX): Remove.  All uses changed to look for __GLOB_GNULIB.
        (__GLOB_CONCAT, __GLOB_XCONCAT, __GLOB_ID): Remove; no longer needed.
        (glob, globfree, glob_pattern_p): Now defined simply in terms of
        rpl_glob, rpl_globfree, rpl_glob_pattern_p.
        (__GLOB_GNULIB): New macro, to keep the glob.h changes clearer
        and to respect the namespace rules better.

2005-09-12  Paul Eggert  <eggert@cs.ucla.edu>

        Merge glibc and coreutils changes into gnulib, plus a few

        them if not _LIBC.  Add __THROW attribute.
        (rol): Remove.
        (struct md5_ctx): Align buffer if using GCC.
        * sha1.h (struct sha1_ctx): Likewise.
        * sha1.c (SWAP): Renamed from the NOTSWAP.  All uses changed.
        The old name was backwards.
        (NOTSWAP): Remove; not used.
        (rol): New macro, moved here from md5.h.

2005-08-31  Paul Eggert  <eggert@cs.ucla.edu>

        On 64-bit hosts (where size_t is 64 bits and int is 32 bits), the
        old glibc regex code mishandles strings longer than 2**31 bytes.
        This patch fixes this when the regex code is used in gnulib
        (i.e., outside glibc).

        This patch should not affect the use of the regex code inside
        glibc.  No doubt this problem also needs to be handled for glibc
        as well, but the result will be an incompatible change to the
        glibc ABI, and the old ABI will have to be supported too.  That
        can be the the subject for another patch.

        * regex.h (_REGEX_LARGE_OFFSETS): New feature-test macro,
        governing whether the rest of this patch is active.  By default,
        the macro is disabled and the patch has no effect.

        (re_string_elem_size_at):
        Use the new types and macros to port to 64-bit hosts.
        Use unsigned types for internal values, so that the code

        that should have been "*err").  g++ problem reported by
        Sam Steingold.
        * regex_internal.h (re_calloc): New macro, consistent with
        re_malloc etc.  All callers of calloc changed to use re_calloc.
        * regex_internal.c (build_wcs_upper_buffer): Return reg_errcode_t,
        not int.  All callers changed.
        * regcomp.c (re_compile_fastmap_iter): Don't use alloca (mb_cur_max);
        just use an array of size MB_LEN_MAX.
        * regexec.c (push_fail_stack): Use re_realloc, not realloc.
        (find_recover_state): Change "err" to "*err"; this fixes what
        appears to be a real bug.
        (check_arrival_expand_ecl_sub): Be consistent about reg_errcode_t
        versus int.

2005-08-25  Jim Meyering  <jim@meyering.net>

        * open-safer.c: Include <config.h>.
        Otherwise, we'd lose LARGEFILE support in any file using
        e.g. "fcntl--.h"

2005-08-24  Paul Eggert  <eggert@cs.ucla.edu>

        * regcomp.c (regerror): 2nd arg is 'restrict', as per POSIX.
        * regex.h (regerror): Likewise.

        * regex.c: Do not include <sys/types.h>, as POSIX no longer
        requires this.  (The code never needed it.)

        * regcomp.c, regex_internal.c, regex_internal.h, regexec.c:
        All uses of recently-renamed identifiers changed to use the new,
        POSIX-compliant names.  The code will build and run just fine
        without these changes, but it's better to eat our own dog food
        and use the standard-conforming names.

        * regex.h: Fix a multitude of POSIX name space violations.
        These changes have an effect only for programs that define
        _POSIX_C_SOURCE, _POSIX_SOURCE, or _XOPEN_SOURCE; they
        do not change anything for programs compiled in the normal way.
        Also, there is no effect on the ABI.

        (_REGEX_SOURCE): New macro.
        Do not include <stddef.h> if _XOPEN_SOURCE and VMS are both
        defined and _GNU_SOURCE is not; this fixes a name space violation.

        Rename the following macros to obey POSIX requirements.
        The old names are still visible as macros if _REGEX_SOURCE is defined.
        (REG_BACKSLASH_ESCAPE_IN_LISTS): renamed from
        RE_BACKSLASH_ESCAPE_IN_LISTS.
        (REG_BK_PLUS_QM): renamed from RE_BK_PLUS_QM.
        (REG_CHAR_CLASSES): renamed from RE_CHAR_CLASSES.
        (REG_CONTEXT_INDEP_ANCHORS): renamed from RE_CONTEXT_INDEP_ANCHORS.
        (REG_CONTEXT_INDEP_OPS): renamed from RE_CONTEXT_INDEP_OPS.
        (REG_CONTEXT_INVALID_OPS): renamed from RE_CONTEXT_INVALID_OPS.
        (REG_DOT_NEWLINE): renamed from RE_DOT_NEWLINE.
        (REG_DOT_NOT_NULL): renamed from RE_DOT_NOT_NULL.
        (REG_HAT_LISTS_NOT_NEWLINE): renamed from RE_HAT_LISTS_NOT_NEWLINE.
        (REG_INTERVALS): renamed from RE_INTERVALS.
        (REG_LIMITED_OPS): renamed from RE_LIMITED_OPS.
        (REG_NEWLINE_ALT): renamed from RE_NEWLINE_ALT.
        (REG_NO_BK_BRACES): renamed from RE_NO_BK_BRACES.
        (REG_NO_BK_PARENS): renamed from RE_NO_BK_PARENS.
        (REG_NO_BK_REFS): renamed from RE_NO_BK_REFS.
        (REG_NO_BK_VBAR): renamed from RE_NO_BK_VBAR.
        (REG_NO_EMPTY_RANGES): renamed from RE_NO_EMPTY_RANGES.
        (REG_UNMATCHED_RIGHT_PAREN_ORD): renamed from
        RE_UNMATCHED_RIGHT_PAREN_ORD.
        (REG_NO_POSIX_BACKTRACKING): renamed from RE_NO_POSIX_BACKTRACKING.
        (REG_NO_GNU_OPS): renamed from RE_NO_GNU_OPS.
        (REG_DEBUG): renamed from RE_DEBUG.
        (REG_INVALID_INTERVAL_ORD): renamed from RE_INVALID_INTERVAL_ORD.
        (REG_IGNORE_CASE): renamed from RE_ICASE.  This renaming is a bit
        unusual, since we can't clash with the POSIX REG_ICASE.
        (REG_CARET_ANCHORS_HERE): renamed from RE_CARET_ANCHORS_HERE.
        (REG_CONTEXT_INVALID_DUP): renamed from RE_CONTEXT_INVALID_DUP.
        (REG_NO_SUB): renamed from RE_NO_SUB.
        (REG_SYNTAX_EMACS): renamed from RE_SYNTAX_EMACS.
        (REG_SYNTAX_AWK): renamed from RE_SYNTAX_AWK.
        (REG_SYNTAX_GNU_AWK): renamed from RE_SYNTAX_GNU_AWK.
        (REG_SYNTAX_POSIX_AWK): renamed from RE_SYNTAX_POSIX_AWK.
        (REG_SYNTAX_GREP): renamed from RE_SYNTAX_GREP.
        (REG_SYNTAX_EGREP): renamed from RE_SYNTAX_EGREP.
        (REG_SYNTAX_POSIX_EGREP): renamed from RE_SYNTAX_POSIX_EGREP.
        (REG_SYNTAX_ED): renamed from RE_SYNTAX_ED.
        (REG_SYNTAX_SED): renamed from RE_SYNTAX_SED.
        (_REG_SYNTAX_POSIX_COMMON): renamed from _RE_SYNTAX_POSIX_COMMON.
        (REG_SYNTAX_POSIX_BASIC): renamed from RE_SYNTAX_POSIX_BASIC.
        (REG_SYNTAX_POSIX_MINIMAL_BASIC): renamed from
        RE_SYNTAX_POSIX_MINIMAL_BASIC.
        (REG_SYNTAX_POSIX_EXTENDED): renamed from RE_SYNTAX_POSIX_EXTENDED.
        (REG_SYNTAX_POSIX_MINIMAL_EXTENDED): renamed from
        RE_SYNTAX_POSIX_MINIMAL_EXTENDED.
        (REG_DUP_MAX): renamed from RE_DUP_MAX.  No need to undef it.
        (REG_UNALLOCATED): Renamed from REGS_UNALLOCATED.
        (REG_REALLOCATE): Renamed from REGS_REALLOCATE.
        (REG_FIXED): Renamed from REGS_FIXED.
        (REG_NREGS): Renamed from RE_NREGS.

        (REG_ICASE, REG_NEWLINE, REG_NOSUB): Do not depend on the values
        of other REG_* macros, since POSIX says the user is allowed to
        #undef these macros selectively.

        (reg_errcode_t): Update comment stating what other tables need
        to be consistent.

        Rename the following enum values to obey POSIX requirements.
        The old names are still visible as macros.
        (_REG_ENOSYS): Renamed from REG_ENOSYS.  Define even if _XOPEN_SOURCE
        is not defined, since GNU is supposed to be a superset of POSIX as
        much as possible, and since we want reg_errcode_t to be a signed
        type for implementation consistency.
        (_REG_NOERROR): Renamed from REG_NOERROR.
        (_REG_NOMATCH): Renamed from REG_NOMATCH.
        (_REG_BADPAT): Renamed from REG_BADPAT.
        (_REG_ECOLLATE): Renamed from REG_ECOLLATE.
        (_REG_ECTYPE): Renamed from REG_ECTYPE.
        (_REG_EESCAPE): Renamed from REG_EESCAPE.
        (_REG_ESUBREG): Renamed from REG_ESUBREG.
        (_REG_EBRACK): Renamed from REG_EBRACK.
        (_REG_EPAREN): Renamed from REG_EPAREN.
        (_REG_EBRACE): Renamed from REG_EBRACE.
        (_REG_BADBR): Renamed from REG_BADBR.
        (_REG_ERANGE): Renamed from REG_ERANGE.
        (_REG_ESPACE): Renamed from REG_ESPACE.
        (_REG_BADRPT): Renamed from REG_BADRPT.
        (_REG_EEND): Renamed from REG_EEND.
        (_REG_ESIZE): Renamed from REG_ESIZE.
        (_REG_ERPAREN): Renamed from REG_ERPAREN.
        (REG_ENOSYS, REG_NOERROR, REG_NOMATCH, REG_BADPAT, REG_ECOLLATE):
        (REG_ECTYPE, REG_EESCAPE, REG_ESUBREG, REG_EBRACK, REG_EPAREN):
        (REG_EBRACE, REG_BADBR, REG_ERANGE, REG_ESPACE, REG_BADRPT, REG_EEND):
        (REG_ESIZE, REG_ERPAREN): Now macros, not enum constants.

        (_REG_RE_NAME, _REG_RM_NAME): New macros.
        (REG_TRANSLATE_TYPE): Renamed from RE_TRANSLATE_TYPE.  All uses
        changed.  But support the old name if the new one is not defined
        and if _REGEX_SOURCE.

        Change the following member names in struct re_pattern_buffer.
        The old names are still supported if !_REGEX_SOURCE.
        The new names are always supported, regardless of _REGEX_SOURCE.
        (re_buffer): Renamed from buffer.
        (re_allocated): Renamed from allocated.
        (re_used): Renamed from used.
        (re_syntax): Renamed from syntax.
        (re_fastmap): Renamed from fastmap.
        (re_translate): Renamed from translate.
        (re_can_be_null): Renamed from can_be_null.
        (re_regs_allocated): Renamed from regs_allocated.
        (re_fastmap_accurate): Renamed from fastmap_accurate.
        (re_no_sub): Renamed from no_sub.
        (re_not_bol): Renamed from not_bol.
        (re_not_eol): Renamed from not_eol.
        (re_newline_anchor): Renamed from newline_anchor.

        Change the following member names in struct re_registers.
        The old names are still supported if !_REGEX_SOURCE.
        The new names are always supported, regardless of _REGEX_SOURCE.
        (rm_num_regs): Renamed from num_regs.
        (rm_start): Renamed from start.
        (rm_end): Renamed from end.

        (re_set_syntax, re_compile_pattern, re_compile_fastmap):
        (re_search, re_search_2, re_match, re_match_2, re_set_registers):
        Prepend __ to parameter names.

        Undo yesterday's changes.

        * regex.h (REG_NOSYS)
        [!defined _XOPEN_SOURCE && 200112L <= _POSIX_C_SOURCE]:
        Define, since POSIX requires it as of 2001.
        (_REG_ENOSYS) [! (defined _XOPEN_SOURCE || 200112L <= _POSIX_C_SOURCE)]:
        New private symbol, used to keep the enum signed in all cases.

        in <http://lists.gnu.org/archive/html/bug-gnulib/2005-07/msg00132.html>.

        Fix problems reported by Sam Steingold in
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00007.html>.
        * regexec.c (sift_states_bkref): Fix portability bug: the code
        assumed that reg_errcode_t is a signed type, which is not
        necessarily true if _XOPEN_SOURCE is not defined.
        * regex_internal.c (calc_state_hash): Put 'inline' before type, since
        some compilers warn about it otherwise.

2005-08-20  Jim Meyering  <jim@meyering.net>

        * regexec.c (regexec, re_search_stub) [!_LIBC]: Omit declaration
        of unused local, dfa.

2005-08-20  Paul Eggert  <eggert@cs.ucla.edu>

        * regex.h (_RE_ARGS): Remove.  No longer needed, since we assume
        C89 or better.  All uses removed.

2005-08-19  Paul Eggert  <eggert@cs.ucla.edu>

        * regex_internal.c (re_acquire_state, re_acquire_state_context)
        [defined lint]: Suppress bogus uninitialized-variable warnings.

        * regcomp.c (duplicate_node): Return new index, not an error code,
        and let the caller return REG_ESPACE if out of space.  This
        removes an uninitialied-variable warning with GCC 4.0.1, and also
        avoids taking the address of a local variable.  All callers
        changed.

2005-08-19  Jim Meyering  <jim@meyering.net>

        * regexec.c (proceed_next_node): Redo local variables to

2005-08-18  Bruno Haible  <bruno@clisp.org>

        * strstr.c (strstr): Fix return value in multibyte case.
        * strcasestr.c (strcasestr): Likewise.

2005-08-17  Jim Meyering  <jim@meyering.net>

        Make the %s format (seconds since the epoch) work for a negative
        number and when used with a zero-padded field width, e.g. %015s.

        * strftime.c (my_strftime): Move the `do_number_sign_and_padding'
        label so that it precedes the code to set `digits'.  Otherwise,
        %0Ns wouldn't work.  Before this change, `date -d @-22 +%05s' would
        print `00-22'.  Now, it prints `-0022', as it should.

2005-08-17  Paul Eggert  <eggert@cs.ucla.edu>

        * regex.h: Remove useless space-before-tab.  From coreutils.

        (mbi_init): Update.
        (mbi_avail, mbi_advance): Let the iteration end before the terminating
        NUL byte, not after it.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * mbchar.h (mb_cmp, mb_casecmp): Order the invalid characters after
        the valid ones. Makes the comparison operations transitive:
        cmp (a, b) < 0 && cmp (b, c) < 0 ==> cmp (a, c) < 0.
        * strcasecmp.c (strcasecmp): Use mb_casecmp.

2005-08-16  Bruno Haible  <bruno@clisp.org>

        * strcase.h (strcasecmp): Add note in comments.
        * strncasecmp.c: Use code from strcasecmp.c.
        * strcasecmp.c: Use mbchar module. Define private mbiter variant.

        * fts-cycle.c (setup_dir, enter_dir, leave_dir, free_dir):
        Use the hash-table-based cycle-detection code not just when
        FTS_TIGHT_CYCLE_CHECK if specified, but also with FTS_LOGICAL.
        Reported by James Youngman in
        <http://lists.gnu.org/archive/html/bug-gnulib/2005-08/msg00011.html>.
        * fts_.h: Mention that with FTS_LOGICAL, we use FTS_TIGHT_CYCLE_CHECK.
        * fts.c (fts_cross_check) [FTS_DEBUG]: s/active_dir_ht/fts_cycle.ht/.
        This lets us compile with -DFTS_DEBUG, once again.
        * fts.c [! _LIBC]: Include "lstat.h" rather than rolling our own.
        * fts.c (fd_safer): Remove decl.
        Include fcntl--.h rather than unistd-safer.h
        (fts_safe_changedir): Don't call fd_safer; no longer needed
        now that we include fcntl--.h.

        * regcomp.c, regexec_internal.c, regex_internal.h, regexec.c:
        New files, synced from libc, except that regex_internal.h
        currently has a small porting fix.

2005-07-03  Paul Eggert  <eggert@cs.ucla.edu>

        Remove the dependency of the strftime module on the tzset module.
        * strftime.c (my_strftime) [! defined _LIBC && ! HAVE_RUN_TZSET_TEST]:
        Copy the input structure, to work around some of the bug with
        Solaris 2.5.1 and Solaris 2.6.  If you still care about these old
        Solaris releases, you should also use the tzset module, but we won't
        require it as a dependency any more since we don't want LGPLed code
        to depend on GPLed code.

2005-07-02  Jim Meyering  <jim@meyering.net>

        Assume HAVE_FCNTL_H (i.e., include <fcntl.h> unconditionally,
        and don't include <sys/file.h>).

2005-07-01  Paul Eggert  <eggert@cs.ucla.edu>

        * xnanosleep.c: Include timespec.h, since OpenBSD 3.4 <time.h>
        declares only 'struct timespec;' (!).

2005-06-29  Jim Meyering  <jim@meyering.net>

        * mkdir-p.c (make_dir_parents): Don't apply sizeof to a hard-coded
        type name.  Use the variable name instead.

        * base64.c (base64_encode): Indent.  Rename 'b64' to avoid
        collision with global variable.  Better indentation.  Don't
        increment buffer pointer beyond buffer end.  Based on comments
        from Paul Eggert <eggert@cs.ucla.edu>.

        * base64.h: Indent.

        and Bruno Haible  <bruno@clisp.org>

        Remove stat module & update lstat.
        * stat.c: Remove this file...
        (slash_aware_lstat): ...moving this content and its support...
        * lstat.c (rpl_lstat): ...into here.
        * lstat.h: New file.

2005-06-23  Paul Eggert  <eggert@cs.ucla.edu>

        * mktime.c: Include <string.h> even if !DEBUG.  (From glibc.)
        (ranged_convert): Don't save conversion in a temporary struct.
        This causes a warning with GCC 4.0.0, and anyway in the typical
        case it's not worth the extra 100 bytes or so of code.
        (ranged_convert, __mktime_internal): When calling a function via a
        pointer P, use P () rather than (*P) (), as we now assume C89 or
        better.

2005-06-22  Paul Eggert  <eggert@cs.ucla.edu>

        * readutmp.c (desirable_utmp_entry): Fix bug where "who -b" and

        * xmalloc.c (HAVE_GNU_CALLOC): New constant.
        (xcalloc): Use it to avoid needless tests.
        Problem reported by Jim Meyering.

2005-06-16  Jim Meyering  <jim@meyering.net>

        * calloc.c (rpl_calloc): Allocate a 1-byte buffer (not 1xS or Nx1)
        when either N or S is zero.

2005-06-16  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * argp.h (__option_is_short): Check upper limit of
        __key. Isprint() requires its argument to have the value
        of an unsigned char or EOF.

2005-06-10  Paul Eggert  <eggert@cs.ucla.edu>

        * fnmatch.c (fnmatch): If there is an encoding error in a
        multibyte string or pattern, fall back on unibyte matching.
        Problem reported by James Youngman.

2005-06-08  Bruno Haible  <bruno@clisp.org>

        * binary-io.h (fileno): Undefine before defining it. Avoids a gcc

2005-05-22  Bruno Haible  <bruno@clisp.org>

        Based on a patch by Derek Price <derek@ximbiot.com>.

2005-05-22  Bruno Haible  <bruno@clisp.org>

        * stdint_.h (_STDINT_H_HAVE_INT64): New macro. Use it in #ifdefs.

        * fts.c (fd_safer) [_LGPL_PACKAGE]: New static function,
        so that unistd-safer.h (GPL'ed code) need not be included.

2005-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        New fts module.
        * fts.c: Don't include "cycle-check.h" or "hash.h".
        (setup_dir, free_dir): New functions.
        (enter_dir, leave_dir): Define trivial
        alternatives of _LGPL_PACKAGE.  Move to fts-cycle.c if !_LGPL_PACKAGE.

        (LEAVE_DIR): Fix typo: pass Fts and Ent to leave_dir.
        (struct Active_dir, AD_compare, AD_hash, enter_dir, leave_dir):
        Move to fts-cycle.c.
        (fts_open): Use setup_dir.
        (fts_close): Use free_dir.
        (fts_read): Have just one copy of the ENTER_DIR code rather than three.
        This adds a label and some gotos, but the alternatives were messier.
        Check for memory allocation failure when entering a dir.
        (fts_stat) [_LGPL_PACKAGE]: Bring back glibc cycle detection code.
        * fts_.h (_LGPL_PACKAGE) [defined _LIBC]: New macro.
        (FTS): New member fts_cycle, that is a union that contains the
        old active_dir_ht and cycle_state.  All uses changed to mention
        fts_cycle.ht and fts_cycle.state.
        * fts-cycle.c: New file, containing GPL'ed code migrated out of
        fts.c, with the following changes:
        (setup_dir, free_dir): New functions.
        (enter_dir): Now returns bool.  Return true if successful, false
        if memory exhausted.  All callers changed.
        Do not bother partly cleaning up on
        memory allocation failure; that is free_dir's job.
        However, free ad if hash_insert fails, to avoid memory leak.
        (enter_dir, leave_dir): Accommodate change to FTS by inspecting
        fts->fts_options to see which union member to use.

2005-05-20  Jim Meyering  <jim@meyering.net>

        * fts.c: Include fts_.h first, to check interface.
        Do not include intprops.h; no longer needed.
        Include cycle-check.h and hash.h, since fts_.h no longer does.
        Remove unnecessary casts of closedir to void.
        (fts_build): Use a simpler method (not involving TYPE_SIGNED) to
        decide whether to decrement nlinks.
        * fts_.h: Do not include hash.h or cycle-check.h; no longer needed.
        (FTS): Use struct hash_table * instead of Hash_table, so that
        we no longer need to include hash.h here.

2005-05-17  Jim Meyering  <jim@meyering.net>

        * fts.c, fts_.h: New files, from coreutils.

        White space changes only.
        * makepath.c (make_path): Port to hosts where leading "//" is special.
        * yesno.c: Include getline.h, not ctype.h.
        (yesno): Don't remove leading white space; POSIX doesn't allow it.
        Use getline to remove arbitrary restriction on response length.

2005-05-13  Bruno Haible  <bruno@clisp.org>

        * stdint_.h (int64_t, uint64_t, int_least64_t, uint_least64_t,

2005-05-10  Yoann Vandoorselaere <yoann.v@prelude-ids.com>

        * getaddrinfo.c: Don't fail when SOCK_STREAM or SOCK_DGRAM are
        specified in ai_socktype. Fix invalid ai_protocol
        check. ai_protocol is usually set to 0 or depending on
        ai_family/ai_socktype to IPPROTO_TCP / IPPROTO_UDP.  Checking for
        SOCK_STREAM / SOCK_DGRAM in ai_protocol was invalid.  Set
        ai_socktype / ai_protocol in the returned addrinfo structure.

2005-05-09  Yoann Vandoorselaere <yoann.v@prelude-ids.com>
            Bruno Haible  <bruno@clisp.org>

        * inet_ntop.h: New file.
        * inet_ntop.c: New file, from glibc with modifications.

2005-05-08  Jim Meyering  <jim@meyering.net>

        * classpath.c (PATH_SEPARATOR): Remove insignificant trailing blank.

2005-05-01  Paul Eggert  <eggert@cs.ucla.edu>

        Merge from coreutils.  Among other things,
        add bulletproofing for cases where stdin, stdout, or stderr are closed.
        * fd-safer.c: New file.
        * fcntl-safer.h, open-safer.c: Remove.
        * chdir-long.c: Fix comment "fetish" -> "coreutils".
        * dup-safer.c: Include unistd-safer.h first.
        Don't include errno.h.
        (dup_safer) [!defined F_DUPFD]: Let fd_safer do the real work.
        * file-type.h: Don't assume invoker included sys/stat.h first.
        * file-type.c: Rely on file-type.h change.
        * getloadavg.c: Include unistd-safer.h.
        (getloadavg): Use safer open.
        * getusershell.c: Include "stdio-safer.h".
        (getusershell): Use safer fopen.
        * long-options.c (long_options): Use NULL rather than 0.
        * modechange.h (mode_free): Remove; all callers changed to invoke
        'free'.
        * modechange.c: Likewise.
        xstrtol.h, stdbool.h, stddef.h: Don't include; no longer needed.
        (MODE_DONE): New constant.
        (struct mode_change): Remove 'next' member.
        (make_node_op_equals): New function; like the old one of the
        same name, except it allocates an array.
        (mode_compile, mode_create_from_ref): Use it.
        (mode_compile): Allocate result as an array, not a linked list.
        Parse octal string ourself, so that we catch mistakes like "+0".
        (mode_adjust): Arg is an array, not a linked list.
        * modechange.c: Include stat-macros.h, xalloc.h.
        (S_ISDIR, S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR):
        (S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH, S_IRXWU):
        (S_IRWXG, S_IRWXO, CHMOD_MODE_BITS):
        Remove.  This is now stat-macros.h's job.
        (talloc): Remove.  All callers replaced by xalloc, so that
        our invokers don't have to worry about reporting memory failures.
        (make_node_op_equals): Remove.
        (MODE_ORDINARY_CHAGE, MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        New constants.
        (struct mode_change): Moved here from modechange.h.
        (mode_append_entry): Remove.
        (mode_compile): Remove MASKED_OPS arg, since it encouraged
        apps to have incorrect behavior.  Use simpler algorithm for head
        and tail.  Don't futz with umask; that's now the job of mode_adjust.
        Detect more invalid usages rather than having somewhat-random behavior.
        Don't insert an "a=" action, as that leads to incorrect behavior.
        (mode_compile, mode_create_from_ref): Return NULL on error instead
        of an enum, since now there's only one way to have an error.  All
        callers changed.
        (mode_adjust): Accept new arg UMASK_VALUE, and interpret it
        at the correct time.  Simplify calculation of "+u" and its ilk.
        Don't mishandle "+X".
        (mode_free): Remove "register" and localize decls.
        * modechange.h (MODE_X_IF_ANY_X, MODE_COPY_EXISTING):
        (struct mode_change): Move to modechange.c; callers don't
        need to see this stuff.
        (MODE_MASK_EQUALS, MODE_MASK_PLUS, MODE_MASK_MINUS, MODE_MASK_ALL):
        (MODE_INVALID, MODE_MEMORY_EXHAUSTED, MODE_BAD_REFERENCE): Remove.
        (mode_change, mode_adjust): Reflect the new signatures noted above.
        * nanosleep.c (rpl_nanosleep): Include "timespec.h" before macros
        that might redefine system include files.
        (siginterrupt) [!HAVE_SIGINTERRUPT]: New macro.
        (my_usleep): Use NULL rather than (void *) 0.
        (rpl_nanosleep) [!defined SA_NOCLDSTOP]:
        Use siginterrupt to specify that system calls should be interrupted.
        (rpl_nanosleep): Move initialization of suspended closer to call of
        my_usleep.
        * readutmp.h (read_utmp): New arg OPTIONS.  All uses changed.
        * readutmp.c: Likewise.  Include signal.h, stdbool.h.
        (desirable_utmp_entry): New function.
        (read_utmp) [defined UTMP_NAME_FUNCTION]: Redo memory allocation
        using x2nrealloc, to simplify logic.
        (read_utmp) [!defined UTMP_NAME_FUNCTION]: Check for overflow in
        size calculation.  Do not assume utmp file is a regular file.
        * readutmp.h (UT_PID): Moved here from ../src/who.c.
        (READ_UTMP_CHECK_PIDS): New constant.
        * save-cwd.c: Include unistd-safer.h.
        (save_cwd): Use fd_safer.
        * tempname.c (S_ISDIR, S_IRUSR, S_IRUSR, S_IWUSR, S_IXUSR): Remove.
        [!_LIBC] Include "stat-macros.h" instead.
        * unistd-safer.h (fd_safer): New decl.

2005-05-01  Oskar Liljeblad  <oskar@osk.mine.nu>

        * byteswap_.h: New file.

2005-04-25  Albert Chin  <china@thewrittenword.com>

        * regex.c: Include <stdio.h>, as a workaround to a Compaq Desktop
        Toolkit C bug.

2005-04-13  Paul Eggert  <eggert@cs.ucla.edu>

        * getdate.y (zone): Allow relunit_snumber after tZONE, so
        that "UTC +1 second" continues to work.  Problem reported
        by Dmitry V. Levin.
        (relunit_snumber): New rule.
        (relunit): Use it.

2005-04-12  Paul Eggert  <eggert@cs.ucla.edu>

        * getdate.y (universal_time_zone_table): New constant.
        (time_zone_table): Remove GMT, UT, UTC entries; they're now in
        universal_time_zone_table.
        (lookup_zone): Prefer universal_time_zone_table to
        local_time_zone_table, so that "GMT" time stamps are allowed in
        London during the summer.  Problem reported by Ian Abbott.

2005-04-12  Jim Meyering  <jim@meyering.net>

        * human.c (humblock): Set *options even when returning due to
        xstrtoumax conversion failure.  Thanks to a used-uninitialized
        warning from gcc-4.

2005-04-09  Jim Meyering  <jim@meyering.net>

        * posixtm.c (posixtime) [lint]: Avoid spurious warning from gcc-4's
        -Wuninitialized: initialize tm0.tm_year.

2005-04-04  Paul Eggert  <eggert@cs.ucla.edu>

        * getdate.y (parser_control): rels_seen is now a boolean, not a
        count, since there's no maximum.  All uses changed.
        Add member dsts_seen.
        (local_zone): Accumulate dsts_seen rather than relying on tm_isdst
        not being INT_MAX.
        (get_date): Initialize dsts_seen, and check that it doesn't go over 1.
        Use pc_rels_seen to decide whther a date is absolute.

        * getdate.y (number): Don't overwrite year.
        (get_date): Initialize pc.year.digits to 0, not 4, to enable above
        check.

2005-04-02  Simon Josefsson  <jas@extundo.com>

        * getaddrinfo.h: Fix OpenBSD compilation failure, inspired by tiny
        patch from Yoann Vandoorselaere <yoann@prelude-ids.org>.

2005-03-27  Jim Meyering  <jim@meyering.net>

        * argmatch.c: Clarify comment: null-terminated -> NULL-terminated.

2005-03-26  Paul Eggert  <eggert@cs.ucla.edu>

        * intprops.h (INT_STRLEN_BOUND, INT_BUFSIZE_BOUND):
        "one's complement" -> "ones' complement" in comment, as per Knuth.
        "value of type" -> "type or expression" in comment.
        * mktime.c, strftime.c: Propagate intprops.h comment nits.

2005-03-26  Jim Meyering  <jim@meyering.net>

        Comment nits.
        * intprops.h: Add the apostrophe in `(one|two)'s complement'.
        Correct typos: s/or/of/.

2005-03-23  Jim Meyering  <jim@meyering.net>

        * canonicalize.c: Remove duplicate `#include "stat-macros.h"'.

2005-03-21  Jim Meyering  <jim@meyering.net>

        Changes imported from coreutils.

        * cycle-check.c: Don't include xalloc.h.

        * path-concat.c: Don't include assert.h.
        (path_concat): Remove assertion that would have triggered
        for ABASE starting with more than one slash.
        Reported by Andreas Schwab.

        * path-concat.c (path_concat): Set *BASE_IN_RESULT
        properly when ABASE is an absolute file name.
        Correct the description of this function.
        Include <assert.h>.
        Add an assertion and a test driver.
        This fixes a bug introduced on 2004-07-02.
        Andreas Schwab reported the resulting failure of cp --parents:
        http://lists.gnu.org/archive/html/bug-coreutils/2005-01/msg00130.html

2005-03-18  Paul Eggert  <eggert@cs.ucla.edu>

        * strftime.c (my_strftime): If the underlying strftime returns 0
        (which shouldn't happen), generate nothing instead of returning 0
        immediately, so that nstrftime (NULL, ...) doesn't return 0.

2005-03-16  Bruno Haible  <bruno@clisp.org>

        * stdint_.h: Use HAVE_LONG_LONG_64BIT instead of HAVE_LONGLONG_64BIT.

2005-03-15  Paul Eggert  <eggert@cs.ucla.edu>

        * strftime.c (my_strftime): Prepend space to format so that we can
        reliably distinguish strftime failure from empty output on POSIX
        hosts.

2005-03-08  Paul Eggert  <eggert@cs.ucla.edu>

        * iconvme.c (SIZE_MAX): New macro, if not already defined.
        (iconv_string): Don't guess a size-zero buffer, as that might cause
        buffer overrun.  Instead, avoid multiplying by MB_LEN_MAX if the
        result would be 'too large', where 'too large' is (heuristically)
        the square root of SIZE_MAX, divided by MB_LEN_MAX to allay
        overflow concerns.  This will prevent some unwanted malloc failures
        when the inputs are very large.

2005-03-15  Bruno Haible  <bruno@clisp.org>

        * regex.c (byte_re_match_2_internal): Rename local variable 'not' to
        'negate'.

        * regex.c (byte_re_match_2_internal): Reduce scope of same_str_p
        variable.

        * regex.c (EXTEND_BUFFER, regcomp): Cast the realloc/malloc results.

2005-03-14  Paul Eggert  <eggert@cs.ucla.edu>

        * mktime.c (TYPE_TWOS_COMPLEMENT, TYPE_ONES_COMPLEMENT,
        TYPE_SIGNED_MAGNITUDE, TYPE_MINIMUM, TYPE_MAXIMUM): Sync from
        intprops.h.
        * strtol.c: Likewise.

2005-03-14  Simon Josefsson  <jas@extundo.com>

        * timegm.h: Use proper prototype CPP guards, reported by Dave Love
        <fx@gnu.org>.

2005-03-14  Jim Meyering  <jim@meyering.net>

        * strftime.c (my_strftime) [HAVE_STRFTIME && ! (_NL_CURRENT
        && HAVE_STRUCT_ERA_ENTRY)]: Initialize the first byte of ubuf[]
        to be nonzero so that we (and caller) can detect the difference
        between a valid zero-length expansion and an error return, even
        when the underlying strftime fails before writing anything into
        that location.

2005-03-10  Jim Meyering  <jim@meyering.net>

        * save-cwd.c [!HAVE_FCHDIR]: Define open, fchdir, and chdir_long
        so that this module works on systems without fchdir.

2005-03-09  Paul Eggert  <eggert@cs.ucla.edu>

        Factor int-properties macros into a single file, except for
        glibc-related files.
        * intprops.h: New file.
        * getloadavg.c: Include it instead of limits.h.
        (INT_STRLEN_BOUND): Remove.
        * human.c: Include intprops.h.
        (group_number): Use INT_STRLEN_BOUND instead of rolling it ourself.
        * human.h (LONGEST_HUMAN_READABLE): Use 146/485 rather than 302/1000.
        * inttostr.h: Include intprops.h instead of limits.h.
        (INT_STRLEN_BOUND, INT_BUFSIZE_BOUND): Remove.
        * mktime.c (TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT): New macros,
        for consistency with intprops.h.
        (time_t_is_integer, twos_complement_arithmetic): Use them.
        * sig2str.h: Include <signal.h>, intprops.h.
        (INT_STRLEN_BOUND): Remove.
        * strftime.c (TYPE_SIGNED): Remove.
        (INT_STRLEN_BOUND): Switch to same implementation as intprops.h.
        * strtol.c: Adjust comments to match intprops.h.
        * userspec.c: Include intprops.h.
        (TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Remove.
        * utimecmp.c, xnanosleep.c, xstrtol.c: Likewise.
        * utimecmp.c (utimecmp): Use TYPE_IS_INTEGER, TYPE_TWOS_COMPLEMENT
        instead of rolling our own expressions.
        * xstrtol.c: Include xstrtol.h first, to test interface.

        * strftime.c: Include <stdbool.h>.  Use bool where appropriate,
        instead of int.
        (my_strftime): Do not mishandle years close to INT_MAX, by doing
        the right thing even if adding 1900 would overflow.  Similarly
        for tm_mon + 1 and tm_yday + 1.
        Make %Y always equivalent to %C%y, and similarly for %G and %g.
        (DO_NUMBER, DO_NUMBER_SPACEPAD): Set digits to d, not a conditional.
        (DO_SIGNED_NUMBER): New macro.
        (my_strftime) [HAVE_TZNAME]: Don't dump core if tp->tm_dst > 1.

2005-03-07  Bruno Haible  <bruno@clisp.org>

        * pagealign_alloc.c (MAP_FILE, MAP_FAILED): Define fallbacks.

2005-03-03  Derek R. Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * pagealign_alloc.h: New file.
        * pagealign_alloc.c: New file.

2005-01-28  Bruno Haible  <bruno@clisp.org>

        * stpncpy.h (stpncpy): Define as a macro without arguments, so that
        stpncpy.c uses it.

2005-03-01  Paul Eggert  <eggert@cs.ucla.edu>

        Remove workaround for bug in Linux kernel 2.6.8 or thereabouts.
        The workaround isn't strictly needed for POSIX conformance, and
        it's too much of a pain to configure and maintain.  We'll ask
        people to fix their kernels instead.
        * xnanosleep.c: Don't include gethrxtime.h or xtime.h.
        (NANOSLEEP_BUG_WORKAROUND): Remove.
        (xnanosleep): Remove the workaround.

2005-02-12  Bruno Haible  <bruno@clisp.org>

        * vasnprintf.c (EOVERFLOW): Define to a fallback if needed.

        * gethrxtime.h, gethrxtime.c, xtime.h: New files.
        * timespec.h (gettime): Return void, since it always
        succeeds now.  All uses changed.
        * gettime.c (gettime) Likewise.
        [HAVE_NANOTIME]: Prefer nanotime.
        Assume gettimeofday succeeds, as POSIX requires.
        Assime time () succeeds, since other code already does.
        * xnanosleep.c: Include xtime.h and gethrxtime.h, not xalloc.h.
        (timespec_subtract): Remove.
        (NANOSLEEP_BUG_WORKAROUND): New constant.
        (xnanosleep): Use gethrxtime rather than gettime; this simplifies
        things considerably.  Use it only on GNU/Linux hosts, since the
        workaround shouldn't be needed elsewhere.

2005-02-24  Bruno Haible  <bruno@clisp.org>

        * gettext.h: Update from GNU gettext 0.14.2.

2005-02-24  Bruno Haible  <bruno@clisp.org>

        returned by OSX/Darwin if the specified buffer is not large
        enough for the hostname.

2005-02-03  Paul Eggert  <eggert@cs.ucla.edu>

        * memrchr.h: New file.
        * chdir-long.c: Include it.
        * memrchr.c [!defined _LIBC]: Include it rather than <string.h>
        Don't bother including stddef.h.

2005-02-03  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * argp-help.c (__argp_help): Create a fake struct argp_state and
        pass it to _help, otherwise the latter coredumps trying to
        dereference state.root_argp.

2005-02-01  Paul Eggert  <eggert@cs.ucla.edu>

        * mountlist.h (MOUNTLIST_H_): New macro, to protect against double
        inclusion.
        Include <sys/types.h>, for dev_t.
        (ME_DUMMY, ME_REMOTE): Move from here....
        * mountlist.c (ME_DUMMY, ME_REMOTE): To here.
        (ME_DUMMY): Count "subfs" as a dummy.  Problem reported by
        Dmitry V. Levin.

        * progname.c (program_name): Initialize.
        Needed when linking statically on MacOS X.

2005-01-28  Bruno Haible  <bruno@clisp.org>

        * javacomp.h: New file, from GNU gettext.
        * javacomp.c: New file, from GNU gettext.

2005-01-26  Bruno Haible  <bruno@clisp.org>

        * javaexec.h: New file, from GNU gettext.
        * javaexec.c: New file, from GNU gettext.

2005-01-26  Simon Josefsson  <jas@extundo.com>

        * gai_strerror.c: Use GPL in header.

2005-01-24  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * argp-help.c (hol_entry_help): Avoid using non-constant
        initializers for struct pentry_state.
        (__argp_error): Check return value of __asprintf
        (__argp_failure): Translate error message

2005-01-21  Jim Meyering  <jim@meyering.net>

        * openat.h (AT_SYMLINK_NOFOLLOW): Define to 4096, so it's the
        same value as for Solaris 9.

        * chdir-long.c (chdir_long): Rewrite to remove limitation on
        component length.  This included changing the parameter to be
        of type `char *' rather than `char const *'.
        * chdir-long.h (chdir_long): Update prototype.

        * openat.c (fdopendir, fstatat): New functions.
        * openat.h: Include headers required for use of DIR and struct stat.
        [AT_SYMLINK_NOFOLLOW]: Define.

        * version-etc.c: Remove version_etc_copyright.
        * version-etc.h (version_etc_copyright): Use [] instead of * in
        prototype, suggested by Paul Eggert <eggert@CS.UCLA.EDU>.

2005-01-20  Paul Eggert  <eggert@cs.ucla.edu>

        * save-cwd.c (save_cwd): Remove code to support the case
        where fchdir is missing or flaky.

2005-01-20  Simon Josefsson  <jas@extundo.com>

        * base64.h (isbase64): Add.

        * base64.c (isb64): Rename to isbase64, use to_uchar instead of
        using a unsigned prototype, don't inline.
        (base64_decode): Use it.

2005-01-19  Bruno Haible  <bruno@clisp.org>

        * sh-quote.h: New file, from GNU gettext.
        * sh-quote.c: New file, from GNU gettext.

2005-01-18  Paul Eggert  <eggert@cs.ucla.edu>

        Merge changes from coreutils, as described below in several
        changelogs dated today.

        * save-cwd.c: Include "save-cwd.h" before other include files.
        (O_DIRECTORY): Remove; not needed here, since "." must be
        a directory.  All uses removed.
        (save_cwd): Use __sgi || __sun, not sun || __sun.  __sun is
        universal on Suns, and we also need to test for IRIX.
        Revamp code to use 'if' rather than '#if'.
        Avoid unnecessary comparison of cwd->desc to 0.

        * utimens.c (futimens): Robustify the previous patch, by checking
        for known valid error numbers rather than observed invalid ones.

2005-01-18  Jim Meyering  <jim@meyering.net>

        * version-etc.c (version_etc_copyright): Update copyright date.

        * utimens.c (futimens): Account for the fact that futimes
        can also fail with errno == ENOSYS or errno == ENOENT.
        Patch from Dmitry V. Levin.

        Change the name of the robust chdir function from chdir to chdir_long.
        * save-cwd.c: Include chdir-long.h rather than chdir.h.
        (restore_cwd): Use chdir_long, not chdir.
        * chdir-long.c: Renamed from chdir.c.
        * chdir-long.h: Renamed from chdir.h.
        [!defined PATH_MAX]: Define chdir_long to chdir on systems like the
        Hurd.

2005-01-18  Bob Proulx  <bob@proulx.com>

        * obstack.c [DEFAULT_ALIGNMENT]: Use an intermediate type to simplify
        offsetof() macro construct to avoid compile failure with native HP-UX
        11.0 ANSI C compiler.

2005-01-06  Bruno Haible  <bruno@clisp.org>

        * stpncpy.c: Remove HAVE_STPNCPY and gnu_stpncpy renaming, redundant
        because stpncpy.m4 takes care of it.

2004-01-24  Bruno Haible  <bruno@clisp.org>

        * progreloc.c (xstrdup): Define as strdup if no xmalloc should be used.

2003-10-09  Bruno Haible  <bruno@clisp.org>

        * progreloc.c: Include xalloc.h instead of xmalloc.h.

2005-01-06  Bruno Haible  <bruno@clisp.org>

        * fwriteerror.h (fwriteerror): Change specification to include fclose.
        * fwriteerror.c: Include <stdbool.h>.
        (fwriteerror): At the end, close the file stream. Record whether
        stdout was already closed.

2004-05-27  Bruno Haible  <bruno@clisp.org>

        * execute.c (environ): Declare if needed.
        * pipe.c (environ): Likewise.
        Reported by Michael Schloh von Bennewitz <michael.schloh@cw.com>.

2005-01-04  Paul Eggert  <eggert@cs.ucla.edu>

        * human.c (SIZE_MAX, UINTMAX_MAX): Move these conditional
        definitions to be after all include files, to avoid collisions.
        Problem reported by Bob Proulx.

2004-12-28  Paul Eggert  <eggert@cs.ucla.edu>

        * error.c [!_LIBC && !ENABLE_NLS]: Do not include "gettext.h";
        not needed.  This removes a dependency on the gettext module.
        [defined _LIBC]: Do not include <libintl.h>; not needed.

2004-12-24  Paul Eggert  <eggert@cs.ucla.edu>

        * c-strtod.c (STRTOD): Depend on HAVE_C99_STRTOLD, not
        HAVE_DECL_STRTOLD.

2004-12-23  Paul Eggert  <eggert@cs.ucla.edu>

        * argp-parse.c: Include <stddef.h>.
        (alignof, alignto): New macros.
        (parser_init): Don't assume that void * is aligned sufficiently
        for struct option.

        * getdate.y (YYSTACK_USE_ALLOCA): Define to 0, since there's no
        need to extend the stack.
        (YYINITDEPTH): New macro, so that the initial stack isn't overly
        large.

2004-12-22  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * argp-parse.c (parser_init): Avoid arithmetics on void pointers.

2004-12-19  Paul Eggert  <eggert@cs.ucla.edu>

        * alloca_.h: Conditionalize on _GNULIB_ALLOCA_H, not _ALLOCA_H.
        Remove now-obsolete comment about AIX.
        * getdate.y: Include <alloca.h> only if HAVE_ALLOCA.
        (YYSTACK_USE_ALLOCA): Define to 0 if !HAVE_ALLOCA.
        (YYMAXDEPTH): New macro.

2004-12-18  Bruno Haible  <bruno@clisp.org>

        * fatal-signal.c (fatal_signals): Make non-const.
        (init_fatal_signals): New function.
        (uninstall_handlers, install_handlers): Ignore signals that were set to
        SIG_IGN.
        (at_fatal_signal): Call init_fatal_signals.
        (init_fatal_signal_set): Likewise. Ignore signals that were set to
        SIG_IGN.
        Reported by Paul Eggert.

2004-12-08  Paul Eggert  <eggert@cs.ucla.edu>

        * getdate.y (textint): New member "negative".
        (time_zone_hhmm): New function.
        Expect 14 shift-reduce conflicts, not 13.
        (o_colon_minutes): New rule.
        (time, zone): Use it to add support for +HH:MM, UTC+HH:MM.
        (yylex): Set the "negative" member of signed numbers.

2004-12-04  Paul Eggert  <eggert@cs.ucla.edu>

        Changes imported from coreutils.
        * hard-locale.c: Assume <locale.h> exists.
        Include "strdup.h".
        (GLIBC_VERSION): New macro.
        (hard_locale): Assume setlocale exists.
        Rewrite to avoid #ifdef.
        Use strdup rather than malloc + strcpy.
        * human.c: Assume <locale.h> exists.
        (human_readable): Assume localeconv exists.

2004-12-01  Jakub Jelinek  <jakub@redhat.com>

        * mktime.c (__mktime_internal): If SEC_REQUESTED != SEC,
        convert T2, not T.  (Imported from libc.)

2004-11-30  Paul Eggert  <eggert@cs.ucla.edu>

        * getcwd.c (is_ENAMETOOLONG): New macro.
        (__getcwd.c): Don't restore errno; glibc doesn't.
        [HAVE_PARTLY_WORKING_GETCWD && !defined AT_FDCWD]: Try system getcwd
        first, falling back to our code only if its results look suspicious.
        Ensure that the resulting buffer is only as large as necessary.

        * readutmp.c: Include readutmp.h first.
        Include <errno.h>, since readutmp.h no longer does that.
        * readutmp.h: Don't include <errno.h>,
        <sys/param.h>, <time.h>; not needed to establish interface.
        (errno): Remove decl.
        (HAVE_STRUCT_XTMP_UT_TYPE): Remove; no longer needed.
        (UT_TYPE_EQ, UT_TYPE_NOT_DEFINED, UT_TYPE_BOOT_TIME,
        UT_TYPE_USER_PROCESS, IS_USER_PROCESS): New macros.

2004-11-28  Simon Josefsson  <jas@extundo.com>

        * base64.h, base64.c: New file.

2004-11-27  Paul Eggert  <eggert@cs.ucla.edu>

        * getcwd.h: New file, which I forgot to check in on 2004-11-25.

2004-11-25  Paul Eggert  <eggert@cs.ucla.edu>

        Fix problems reported by Scott S. Tinsley for HP-UX 11.11 using
        HP's ANSI C compiler.
        * fsusage.c (statvfs) [HAVE_SYS_STATVFS_H]: Remove decl.
        Declaring int functions causes warnings on some modern systems and
        shouldn't be needed to compile on ancient ones.
        * same.c (MIN) [defined MIN]: Don't define, since it's already
        defined.

        * getcwd.c: Replace by a copy of glibc/sysdeps/posix/getcwd.c, but
        with the following changes.
        (__set_errno): Parenthesize properly.
        Include <stdbool.h>.
        (MIN, MAX, MATCHING_INO): New macros.
        (__getcwd): Define with prototype, not K&R form.
        Use heuristics to allocate default buffer on stack if possible.
        If AT_FDCWD is defined, use openat and fstatat to avoid O(N**2)
        behavior, and to avoid the PATH_MAX limit when computing
        ../../../../...
        Use MATCHING_INO to compare inode number to file.
        Check for arithmetic overflow in size calculations.
        Fix bug in reallocation of dot array that caused getcwd to fail
        on directories nested deeper than 75.
        Be more careful about saving errno on error.
        Do not use realloc; use only free+malloc, as this is a bit
        more flexible and avoids a needless copy operation.
        Do not inspect st_dev and st_ino for symbolic links; POSIX
        doesn't specify the latter.
        Check for closedir errors.
        Avoid needless casts.
        Use "#ifdef weak_alias" around weak_alias, to be like other
        glibc code.
        The following changes to getcwd.c have effect only when used in
        gnulib; they have no effect inside glibc proper.
        (#pragma alloca) [defined _AIX && !defined __GNUC__]: Remove,
        as alloca isn't used.
        (alloca, __alloca): Likewise.
        [!_LIBC]: Include "getcwd.h", "mempcpy.h".
        Include <stddef.h>, <stdlib.h>, <string.h>, <limits.h>
        unconditionally, as gnulib assumes C89 or better.
        Do not include <sys/param.h>.
        (errno) [!defined __GNU_LIBRARY__ && !defined STDC_HEADERS]: Remove
        no-longer-necessary 'extern int errno' decl; gnulib assumes C89 or
        better.
        (NULL) [!defined NULL]: Remove; we assume C89 or better.
        Include <dirent.h> in a way that is compatible with modern Autoconf.
        (_D_ALLOC_NAMELEN, _D_EXACT_NAMLEN):
        New macros, if not already defined.
        Include <unistd.h> if _LIBC, not if __GNU_LIBRARY__.
        Use "_LIBC", not "defined _LIBC", for consistency.
        (HAVE_MEMPCPY): Remove; no longer needed now that gnulib has
        a mempcpy module.
        (__lstat, __closedir, __opendir, __readdir) [!_LIBC]: New macros.
        (GETCWD_RETURN_TYPE): Remove.  All uses replaced by char *.
        * xgetcwd.c: David MacKenzie's old code was removed, so give
        credit only to Jim Meyering and adjust the copyright dates.
        Do not include <limits.h>, <stdio.h>, <sys/types.h>,
        <stdlib.h>, <unistd.h>, "pathmax.h".
        Instead, include "xgetcwd.h" (first) and "getcwd.h".
        (INITIAL_BUFFER_SIZE): Remove.
        (xgetcwd): Rely on getcwd, since we now depend on a reliable one.

2004-11-23  Jim Meyering  <jim@meyering.net>

        * getopt_.h: Remove trailing blanks.

2004-11-23  Paul Eggert  <eggert@cs.ucla.edu>

        * utimens.c (__attribute__, ATTRIBUTE_UNUSED): New macros.
        (futimens): New function, which uses futimes if available.
        (futimens, utimens): Support timespec==NULL, with same semantics
        as utime and utimens.
        * utimens.h (futimens): New decl.

2004-11-23  Jim Meyering  <jim@meyering.net>

        * __fpending.c: Add comment.

2004-11-23  Sergey Poznyakoff  <gray@Mirddin.farlep.net>

        * getopt_.h: Re-addition of __getopt_argv_const caused
        redefinition warnings. To avoid them, include the defines
        in `#if !defined __need_getopt ... #endif'. The only place
        where __getopt_argv_const is used is in definitions
        of getopt_long and getopt_long_only below, which are as well
        protected by `#ifndef __need_getopt'.
        [defined __GETOPT_PREFIX && !defined __need_getopt]: Undef
        __need_getopt after including <stdio.h> and <unistd.h> These
        headers might have defined it.

2004-11-20  Paul Eggert  <eggert@cs.ucla.edu>

        * getopt_.h (__GETOPT_CONCAT, __GETOPT_XCONCAT, __GETOPT_ID):
        New macros.
        (getopt, getopt_long, getopt_long_only, optarg, opterr, optind,
        optopt): Use them instead of invoking ## directly; otherwise, the
        symbols will be __GETOPT_PREFIXgetopt rather than rpl_getopt.

2004-11-19  Bruno Haible  <bruno@clisp.org>

        * strtok_r.c: Move comments from here...
        * strtok_r.h: ... to here.

2004-11-17  Paul Eggert  <eggert@cs.ucla.edu>

        * realloc.c (rpl_realloc): Call 'free' if n==0, since realloc
        might fail.  Problem reported by Yoann Vandoorselaere.
        * calloc.c (rpl_calloc): Defend against buggy calloc implementations
        that mishandle size_t overflow.

2004-11-16  Paul Eggert  <eggert@cs.ucla.edu>

        * canon-host.c: Include "strdup.h".
        (canon_host): Use getaddrinfo if available, so that IPv6 works.
        Use strdup instead of malloc/strcpy to duplicate strings.

        * human.h (LONGEST_HUMAN_READABLE): Add 1 for space before unit.
        (human_space_before_unit): New constant.
        * human.c (human_readable): Support it.

        * xgetcwd.c: Include <limits.h>, for PATH_MAX.
        (xgetcwd): Set errno correctly when failing.
        Work around Solaris 9 bug: getcwd sets errno==ERANGE even though
        the failure is actually due to a PATH_MAX problem.

        Further getopt changes to make it more likely that glibc will
        buy the changes back.
        * getopt.c (POSIXLY_CORRECT): New constant.
        (getopt): Use it, so to preserve glibc semantic
        * getopt1.c (getopt_long, getopt_long_only): Arg is char * const *
        when compiling for libc.
        * getopt_.h (__getopt_argv_const): Bring it back.
        (getopt_long, getopt_long_only): Use it.

        * getopt.c (_getopt_initialize, _getopt_internal_r, _getopt_internal):
        New arg POSIXLY_CORRECT.  All callers changed.
        (getopt): Argv is now char * const *, as per standard.
        (_getopt_internal_r, _getopt_internal): Argv is now char **,
        not char *__getopt_argv_const *.
        * getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,
        _getopt_long_only_r): Likewise.

        * closeout.c: Include "__fpending.h" once again.
        Include <stdbool.h>.
        (close_stdout): Don't fail just because stdout was closed initially,
        since some programs don't write to stdout in the normal course of
        operation (other than --version and --help), and we don't want this
        function to make e.g. `touch file >&-' fail.
        But do fail if it was closed and someone has tried to write to it.
        E.g., `printf foo >&-' must fail.

2004-11-11  Simon Josefsson  <jas@extundo.com>

        * strtok_r.h, strtok_r.c: New file.

2004-11-11  Paul Eggert  <eggert@cs.ucla.edu>

        * getopt_.h (__getopt_argv_const): New macro, to be used so that
        we can stop lying to compilers about the constness of argv when we
        are compiled outside glibc.
        (getopt, getopt_long, getopt_long_only): Use it.
        * getopt.c (_getopt_initialize, _getopt_internal_r, _getopt_internal,
        getopt): Likewise.
        * getopt1.c (getopt_long, _getopt_long_r, getopt_long_only,

        Include <stdlib.h> and <stdio.h>, and <unistd.h> if available.
        Then rename getopt to __GETOPT_PREFIX##getopt, and so forth for
        the other external symbols.
        (getopt) [!defined __GNU_LIBRARY]: Use prototype, not old-style
        declaration, since the above renaming now works around collisions.

2004-11-11  Jim Meyering  <jim@meyering.net>

        * linebreak.c: Remove trailing blanks.
        * alloca_.h: Likewise.

        (TIME_T_MIDPOINT, ydhms_diff, __mktime_internal): Use it.
        Problem reported by Mark D. Baushke in
        <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00071.html>.
        * getdate.y (SHR): Likewise.

        * strftime.c (SHR): Likewise.
        (tm_diff): Use it.
        * quotearg.c (struct quoting_options): Use unsigned int for
        quote_these_too, so that right shifts are well defined.  All uses
        changed.

2004-11-10  Simon Josefsson  <jas@extundo.com>

        * getaddrinfo.h, getaddrinfo.c: New files.

                * allocsa.h (sa_alignof): Define differently with HP-UX cc, to
                avoid a bug of this cc on HP-UX 10.20 dealing with enums.
                Reported by Christopher Seip <chris.seip@hp.com>.

        * xreadlink.c (MAXSIZE): New macro.
        (xreadlink): Use it instead of SSIZE_MAX.  Ensure initial buffer
        size does not exceed MAXSIZE.  Avoid cast.
        As suggested by Mark D. Baushke in
        <http://lists.gnu.org/archive/html/bug-gnulib/2004-11/msg00009.html>,
        if readlink fails with buffer size just under MAXSIZE, try again
        with MAXSIZE.

        and  Paul Eggert  <eggert@cs.ucla.edu>

        (get_date): Overparenthesize to avoid GCC warning.

2004-11-02  Bruno Haible  <bruno@clisp.org>

        * setenv.h (unsetenv): Define as a macro if the system's unsetenv()
        function returns void.

        already declared.

2004-10-29  Paul Eggert  <eggert@cs.ucla.edu>

        * getdate.y: Add support for TZ="foo" within a date string.
        Fix some bugs near time_t boundaries.  Reject dates with

        * getdate.y: Use Bison 1.875 features, and some minor
        code cleanups.  This change does not affect semantics.
        Don't include <stdlib.h>; no longer needed.
        Don't include unlocked-io.h; only the "#if TEST" code uses
        stdio, and performance isn't crucial there.
        (PC, YYLEX_PARAM, YYPARSE_PARAM): Remove; replaced by
        Bison 1.875 features as described below.
        All uses of "PC." replaced by "pc->".
        (YYSTYPE): Add a forward declaration.
        (yylex, yyerror): Use full prototypes in forward decls.
        Use "%pure-parser" rather than obsolescent "%pure_parser".

        (meridian_table, month_and_day_table, time_units_table,
        relative_time_table, time_zone_table, military_table,
        lookup_zone, lookup_word, get_date):
        Use NULL instead of 0 where appropriate.
        (to_hour): Avoid abort (), to avoid a dependency on
        stdlib.h.
        (yyerror, yylex): Now accepts parser_control * arg.
        (main) [TEST]: Use '\0' rather than 0 for char.

2004-10-22  Paul Eggert  <eggert@cs.ucla.edu>

        * getpagesize.c (getpagesize): Don't assume <sys/param.h> exists.
        It's now the caller's responsibility to handle the case where
        !HAVE_GETPAGESIZE && !defined getpagesize.

        * argmatch.c (enum backuptype) [defined TEST]: Likewise.
        * backupfile.c (check_extension, numbered_backup):
        Rename locals to avoid shadowing 'basename'.

        Merge from tar.
        * argp-help.c (make_hol, hol_append): Don't assume that
        SIZE_MAX is a valid preprocessor constant.
        (__argp_basename): Change from "#ifndef _LIBC"
        to "#ifndef __argp_short_program_name", so that
        we don't compile these functions for tar.

        More merges from coreutils.

        (same_name): Return bool, not int.
        * same.c (same_name): Likewise.

        if not already defined.

        * xgetcwd.c (errno): Don't declare; we assume C89 or better now.

2004-08-03  Paul Eggert  <eggert@cs.ucla.edu>

2004-07-09  Simon Josefsson  <jas@extundo.com>

        * getndelim2.c: Include stddef.h, for ptrdiff_t.  (FreeBSD 4.9

2004-06-01  Paul Eggert  <eggert@cs.ucla.edu>
        and  Jim Meyering  <jim@meyering.net>

        Merge from coreutils CVS.

        * stat-macros.h: New file, with contents from file-type.h
        and coreutils' system.h.
        * file-type.c: Include "stat-macros.h".
        * file-type.h (file_type): Move all macro definitions to new file,

        Wrap old code with this conditional.
        [CHOWN_MODIFIES_SYMLINK]: Try to work around a chown
        function that does not dereference symlinks.
        * lchown.c (lchown) [CHOWN_MODIFIES_SYMLINK]: Just call chown.

        * xreadlink.c: Include xreadlink.h first, to catch .h file
        dependency problems.

2004-05-30  Paul Eggert  <eggert@cs.ucla.edu>

        * xmalloc.c (HAVE_MALLOC, HAVE_REALLOC): Do not require these
        macros to be defined.
        (xnmalloc_inline, xnrealloc_inline, xcalloc): Do not die if
        the allocator returns NULL because the requested size is zero.

2004-05-20  Paul Eggert  <eggert@cs.ucla.edu>

        * malloc/obstack.c (_obstack) [defined _LIBC]: Bring back this
        var.  Add comment explaining why libc still defines it.  This
        merges the following patch from glibc:
        http://sources.redhat.com/ml/libc-alpha/2004-05/msg00157.html

2004-05-19  Paul Eggert  <eggert@cs.ucla.edu>

        * obstack.c (_obstack): Remove unused variable.  It hasn't been
        present in glibc since revision 1.1 of this file.
        * obstack.h (_obstack_free, obstack_1grow, obstack_1grow_fast,
        obstack_alignment_mask, obstack_alloc, obstack_base,
        obstack_blank, obstack_blank_fast, obstack_chunk_size,

        obstack_next_free, obstack_object_size, obstack_ptr_grow,
        obstack_ptr_grow_fast, obstack_room): Remove declarations of
        nonexistent functions.

2004-05-17  Derek R. Price  <derek@ximbiot.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        * argp-help.c, argp-parse.c: Assume <alloca.h> rather than freecoding.

2004-05-14  Bruno Haible  <bruno@clisp.org>

        * vasnprintf.c (VASNPRINTF): Correctly handle the case of a precision
        that consists of a '.' followed by an empty digit string.
        Patch by Tor Lillqvist <tml@iki.fi>.

2004-05-17  Paul Eggert  <eggert@cs.ucla.edu>

        Port obstack to the AS/400, where pointers are 16 bytes wide and
        you cannot cast an integer to a valid pointer.  This patch is
        currently waiting to be integrated into glibc; see
        <http://sources.redhat.com/ml/libc-alpha/2004-05/msg00073.html>.

        * obstack.h (__PTR_TO_INT, __INT_TO_PTR): Remove.
        All uses of __INT_TO_PTR (PTR_TO_INT ...) replaced by __PTR_ALIGN.
        (__BPTR_ALIGN, __PTR_ALIGN): New macros.
        (struct obstack): temp member is now a union of a pointer and
        an integer, instead of an integer.  All integer uses changed.
        This does not affect the physical layout of struct obstack,
        except on hosts (like the AS/400) where the size or alignment of
        void * is greater than that of ptrdiff_t.
        (obstack_finish) [! (defined __GNUC__ && defined __STDC__ &&
        __STDC__)]: Store temporary in pointer member of union, not
        integer member.
        * obstack.c: Include <stddef.h>, for offsetof.
        (struct fooalign): Remove; it doesn't need a name.
        (union fooround): Change double to long double, and add void *.
        (DEFAULT_ALIGNMENT): Use offsetof to compute.
        (DEFAULT_ALIGNMENT, DEFAULT_ROUNDING): Now an enum constant,
        not a macro.  Hence the values are always int; so remove all
        casts-to-int in uses.

2004-05-16  Paul Eggert  <eggert@cs.ucla.edu>
            Derek Price  <derek@ximbiot.com>

        * alloca.c: Include <alloca.h>, to get our interface.
        * alloca_.h: Use __alloca on AIX, so that we don't have to
        include <alloca.h> first.  Use C89 prototype for alloca; this
        requires including <stddef.h> for size_t.  Use extern "C" if C++.
        Use #elif for simplicity, since we can assume C89 now.
        Don't try to source the system alloca.h since it will not be found
        and to prevent recursively including its replacement.
        * fnmatch.c: Include <alloca.h> instead of opencoding.
        * regex.c: Likewise.

2004-05-16  Derek Price  <derek@ximbiot.com>
            Paul Eggert  <eggert@cs.ucla.edu>

        getline cleanup.  This changes the getndelim2 API: both order of
        arguments, and meaning of delim2 (now uses EOF, not 0, to indicate
        no delimiter).

        * getline.c: Don't include stddef.h or stdio.h, since our
        interface does that.
        (getline): Always use getdelim, so that we don't have two
        copies of this code.
        * getndelim2.c: Include <limits.h>, <inttypes.h>, <stdint.h>
        if available.
        (PTRDIFF_MAX, SIZE_MAX, SSIZE_MAX): Define if not defined.
        (GETNDELIM2_MAXIMUM): New macro.
        (getndelim2): Reorder arguments.  delim==EOF now means no delimiter,
        instead of the old practice of delim2==0.  All callers changed.
        Return -1 on overflow, instead of returning junk.
        Do not set *linesize unless allocation succeeds.
        * getndelim2.h: Do not include stddef.h; no longer needed, now
        that we include sys/types.h.
        * getnline.h: Likewise.
        * getndelim2.h (GETNLINE_NO_LIMIT): New macro.
        (getndelim2): Reorder arguments.
        * getnline.c (getnline, getndelim):
        Don't discard the NMAX argument.
        (getnline): Invoke getndelim, to avoid code duplication.
        * getnline.h (GETNLINE_NO_LIMIT): New macro, used instead
        of (size_t) -1 by callers of the getnline family.

2004-05-13  Paul Eggert  <eggert@cs.ucla.edu>

        * nanosleep.c (suspended): Change its type from int to
        sig_atomic_t volatile.
        (first_call): Make it private to rpl_nanosleep, and have it
        be zero initially as that's a bit faster.
        (my_usleep): Round up fractional times instead of truncating them,
        as this is the usual meaning for 'sleep'.

        * gettime.c (gettime): Fall back on `time' if `gettimeofday'
        doesn't work.
        * settime.c: Include <unistd.h>, for stime (on Solaris 8, anyway).
        (ENOSYS): Define if not defined.
        (settime): Fall back on stime if it exists and settimeofday fails.
        But don't bother with fallbacks if a method fails with errno == EPERM.

2004-05-11  Jim Meyering  <jim@meyering.net>

        Prior to this change, the save_cwd caller required read access to the
        current directory on most systems (ones with the fchdir function).

        * save-cwd.c (save_cwd) [HAVE_FCHDIR]: If opening `.' read-only
        fails, try write-only, and finally, resort to using xgetcwd.

2004-05-06  Paul Eggert  <eggert@cs.ucla.edu>

        * obstack.c, obstack.h: Import changes from libc.

2004-04-28  Bruno Haible  <bruno@clisp.org>

        * findprog.c (find_in_path): Treat Cygwin like Windows, since it also
        implicitly appends .exe to executables.
        * localcharset.c (ISSLASH): Treat Cygwin like Windows, since it now
        accepts Windows pathnames.
        * pathname.h (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN): Treat
        Cygwin like Windows, since it now accepts Windows pathnames.
        * progreloc.c (ISSLASH, IS_PATH_WITH_DIR, FILESYSTEM_PREFIX_LEN): Treat
        Cygwin like Windows, since it now accepts Windows pathnames.
        Reported by Derek Robert Price <derek@ximbiot.com>.

2004-04-20  Jim Meyering  <jim@meyering.net>

        * getndelim2.c (getndelim2): Upon realloc failure, don't leak memory.

2004-04-20  Jim Meyering  <jim@meyering.net>
            Bruno Haible  <bruno@clisp.org>

        * localcharset.c (get_charset_aliases) [!VMS && !WIN32]: Don't leak
        memory when realloc fails.

2004-04-18  Jim Meyering  <jim@meyering.net>

        * readutmp.c (read_utmp) [UTMP_NAME_FUNCTION]: Upon realloc failure,
        don't leak memory and do call END_UTMP_ENT.

2004-04-11  Paul Eggert  <eggert@twinsun.com>

        * inttostr.h: Include <limits.h> unconditionally, since we assume C89.
        (CHAR_BIT): Remove, since we assume C89.
        Include <stdint.h> if available, as per current Autoconf CVS advice.

2004-03-30  Paul Eggert  <eggert@twinsun.com>

        * cloexec.h, cloexec.c (set_cloexec_flag): Return int
        not bool, to be more consistent with Unix conventions.
        Suggested by Bruno Haible.

        Merge from coreutils.

        * imaxtostr.c, inttostr.c, inttostr.h, offtostr.c, umaxtostr.c:
        New files.

        * getdate.h: Include stdbool.h, and timespec.h instead of
        the usual <time.h> dance.
        (get_date): Change signature to support fractional time stamps.
        All callers changed.
        * getdate.y: Include "getdate.h" first, as we can now
        assume C89 and don't need to worry about 'const'.
        Similarly, include "unlocked-io.h" near start, not in middle.
        Include <limits.h>.
        (textint.value): Use long int rather than int.
        (textint.digits): Use size_t rather than int.
        (BILLION, LOG10_BILLION): New constants.
        (parser_control): New member rel_ns.  Members day_ordinal,
        time_zone, month, day, hour, minutes, rel_year, rel_month,
        rel_day, rel_hour, rel_minutes, rel_seconds
        are now long int, not int.  Member seconds is now struct timespec,
        not int.  New member timespec_seen.  Members dates_seen, days_seen,
        local_zones_seen, rels_seen, times_seen, zones_seen are now size_t,
        not int.
        (%union.intval): Now long int, not int.
        New member timespec.
        (tSDECIMAL_NUMBER, tUDECIMAL_NUMBER): New tokens.
        (seconds, signed_seconds, unsigned_seconds): New nonterminals.
        (spec): Now is a timespec or an item list.
        (timespec, items): New nonterminals.
        (time, rel, relunit, number, get_date):
        Add support for fractional seconds.
        (time): Fix bug: seconds weren't cleared in "00:00 +0000" syntax.
        (gmtime, localtime, mktime): Remove decls; not needed with C89.
        (to_hour): First arg is now long int, not int.
        (to_year): Returns long int, not int.
        Don't treat year -70 like 70.
        (tm_diff): Returns long int, not int.
        (lookup_word): Use bool instead of int when appropriate.
        (yylex): Use size_t for count, not int.
        Detect overflow when parsing large integer constants.
        Add support for fractions.
        (get_date): Make pointers 'const' if possible.
        Use more-portable code to detect integer overflow.
        (main) [TEST]: Adjust to above changes.  Test for localtime failure.
        Don't use ctime; it's not reliable if the year has >4 digits.

        * human.c (humblock): Inspect BLOCKSIZE if BLOCK_SIZE isn't set.
        This is for compatibility with BSD.

        * timespec.h (ST_TIME_CMP_NS, ST_TIME_CMP): Define.
        (ATIME_CMP, CTIME_CMP, MTIME_CMP, TIMESPEC_NS): Likewise.
        From coreutils' system.h.

        * userspec.c: Don't include "posixver.h".
        (parse_user_spec): Fall back on USER.GROUP parsing, regardless
        of POSIX version, as POSIX 1003.1-2001 allows that behavior as a
        compatible extension.  Simplify code by removing a boolean int
        that was always nonzero if a string was nonnull.

2004-03-30  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.

        * mountlist.c [HAVE_SYS_UCRED_H]: Include grp.h before sys/ucred.h.

        * readtokens.c (readtoken): Don't leak 64 bytes when reading
        an empty input stream.

        * readtokens.c: Include <stdbool.h>.
        (readtoken): Use `size_t' rather than int/long.
        All callers adjusted.
        Use `bool' rather than `int' where appropriate.
        Use memset rather than an explicit loop.
        Use x2nrealloc rather than xrealloc.
        Allow the use of `\0' as a delimiter.
        (readtokens): Likewise.
        * readtokens.h (readtoken, readtokens): Update prototypes.

        * getloadavg.c (getloadavg): Don't assume setlocale returns
        nonnull.

2004-03-29  Paul Eggert  <eggert@twinsun.com>

        Merge changes to getloadavg.c from coreutils and Emacs.

        * getloadavg.c [!defined HAVE_SETLOCALE] (setlocale):
        Define to an expression, not to the empty string.
        Include cloexec.h and xalloc.h.
        (getloadavg): Restore LC_NUMERIC locale after setting it temporarily.
        Use set_cloexec_flag rather than rolling our own.
        * cloexec.c, cloexec.h: New files.

2004-03-18  Paul Eggert  <eggert@twinsun.com>

        * getopt.h: Sync with libc CVS.

2004-03-18  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        * mbswidth.h: Include <wchar.h> only if HAVE_DECL_MBSWIDTH_IN_WCHAR_H,
        not on all platforms that have <wchar.h>.
        * mbswidth.c: Include <stdio.h> and <time.h> before <wchar.h>.

2004-03-09  Paul Eggert  <eggert@twinsun.com>

        * argp-parse.c, getopt.c, getopt.h, getopt1.c:
        Sync with libc CVS.
        * getopt_int.h: New file, also synced from libc.

2004-03-07  Paul Eggert  <eggert@twinsun.com>

        * c-stack.c (SIGACTION_WORKS): New macro.  Use it instead of long
        '#if' expressions.  Unlike the code it replaces, it does not
        depend on (defined _SC_PAGESIZE).  However, it does depend on
        HAVE_STRUCT_SIGACTION_SA_SIGACTION; this last change fixes a bug
        first reported by Jason Andrade in
        <http://mail.gnu.org/archive/html/bug-textutils/2003-03/msg00027.html>.

2004-01-18  Simon Josefsson  <jas@extundo.com>

        * strdup.h: New file.
        * strdup.c: Include it.
        * path-concat.c: Include strdup.h. Drop strdup declaration.
        * userspec.c: Include strdup.h. Drop strdup declaration.

2004-02-06  Karl Berry  <karl@gnu.org>

        * config.charset: update from gettext 0.14.1.

2004-02-05  Paul Eggert  <eggert@twinsun.com>

        Add comments and code, prompted by suggestions from Bruno Haible
        for sh-quote.
        * quotearg.h (quotearg_alloc): New decl.  Improve the comments
        describing the enum quoting_style values.
        * quotearg.c (quotearg_alloc): New function.
        (quotearg_buffer_restyled): Treat lone { and } as special.
        Treat = as special.  Work around bug with older shells
        that "see" a '\' that is really the 2nd byte of a multibyte char.
        Quote empty string with shell_quoting_style.

2004-02-03  Bruno Haible  <bruno@clisp.org>

        * pipe.h: New file, from GNU gettext.
        * pipe.c: New file, from GNU gettext.

2004-01-27  Bruno Haible  <bruno@clisp.org>

        * execute.h: New file, from GNU gettext.
        * execute.c: New file, from GNU gettext.
        * w32spawn.h: New file, from GNU gettext.

2004-01-23  Paul Eggert  <eggert@twinsun.com>

        Exit-status fix from coreutils.

        Use exit_failure consistently in place of EXIT_FAILURE,
        so that program exit statuses are consistent on failure.

        * argmatch.c (ARGMATCH_DIE) [! defined ARGMATCH_DIE]:
        Include "exitfail.h", and use exit_failure rather than EXIT_FAILURE.
        * argmatch.h: Comment fix to match the above.
        * obstack.c (obstack_exit_failure) [!defined _LIBC]:
        Now a macro referring to exit_failure, instead of a separate
        variable.  Include "exitfail.h" to get it.
        * xstrtol.h: Include "exitfail.h".
        (STRTOL_FATAL_ERROR): Exit with status exit_failure, not 2.

        * long-options.c (parse_long_options): Use prototype
        for usage function arg.  Pass it EXIT_SUCCESS rather than 0,
        for clarity.

2004-01-21  Jim Meyering  <jim@meyering.net>

        * mktime.c (__mktime_internal) [!_LIBC]: Define to mktime_internal
        so as not to conflict with a different-sized __mktime_internal
        function in GNU libc.
        * timegm.c (__mktime_internal) [!_LIBC]: Likewise.
        Problem building statically-linked `ls' reported by Michael Brunnbauer.

2004-01-18  Paul Eggert  <eggert@twinsun.com>

        Merge from diffutils.

        * file-type.c (file_type): Add typed memory objects.
        * file-type.h (S_TYPEISTMO): New macro.

        * c-stack.h (c_stack_action): Remove argv argument.
        * c-stack.c (c_stack_action): Likewise.  All uses changed.
        (die): Don't calculate message unless segv_action returns.
        (get_stack_location, min_address_from_argv, max_address_from_argv,
        volatile stack_base, volatile_stack_size): Remove.
        (segv_handler): If ! HAVE_XSI_STACK_OVERFLOW_HEURISTIC, assume
        that every segmentation violation is a stack overflow.  (Ouch!)
        See Debian bug 136249 (still outstanding) for more info about why
        HAVE_XSI_STACK_OVERFLOW_HEURISTIC fails on Linux kernels.

2003-11-30  Bruno Haible  <bruno@clisp.org>

        Safer stack allocation.

        (alloca): Remove fallback definition.
        (freea): Remove macro.
        (__add_to_environ) [!_LIBC]: Use allocsa instead of alloca. Use freesa
        instead of freea.

2003-10-17  Bruno Haible  <bruno@clisp.org>

        * binary-io.h: Avoid warnings on Cygwin.

2003-12-28  Bruno Haible  <bruno@clisp.org>

        * wait-process.c (wait_subprocess): Add ignore_sigpipe argument.
        * wait-process.c (wait_subprocess): Likewise. Handle SIGPIPE specially.

2003-11-28  Bruno Haible  <bruno@clisp.org>

        * wait-process.c (cleanup_slaves): Use ANSI C declaration.

2003-11-27  Bruno Haible  <bruno@clisp.org>

        * wait-process.c: On Windows, include windows.h. Needed on mingw.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * wait-process.c (wait_process): Disable the 2003-10-31 waitid() patch.

2003-11-24  Bruno Haible  <bruno@clisp.org>

        * xallocsa.h: New file, from GNU gettext.
        * xallocsa.c: New file, from GNU gettext.

2003-11-24  Bruno Haible  <bruno@clisp.org>

        * allocsa.h: New file, from GNU gettext.
        * allocsa.c: New file, from GNU gettext.

2003-11-24  Bruno Haible  <bruno@clisp.org>

        * eealloc.h: New file.

2004-01-15  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.

        * md5.h (rol) [__GNUC__ && __i386__]: Don't use `asm' code.  These
        days, gcc-3.x does better all by itself.  Patch from Dean Gaudet:
        http://mail.gnu.org/archive/html/bug-coreutils/2003-11/msg00144.html

        * posixver.c (DEFAULT_POSIX2_VERSION): Use definition of new,
        optional configure-time default.

        * version-etc.c (version_etc_copyright): Update copyright date.

        * xreadlink.c (xreadlink): Correct outdated comment.

        Merge from coreutils.

        * posixver.c: Include posixver.h.

        * same.c: Include <stdbool.h>, <limits.h>.
        (_POSIX_NAME_MAX): Define if not defined.
        (MIN): New macro.
        (same_name): If file names are silently truncated, report
        that the file names are the same if they are the same after
        the silent truncation.

        * xstrtod.h (xstrtod): Accept an extra arg, specifying the
        conversion function.
        * xstrtod.c (xstrtod): Likewise.  All callers changed to
        include c-strtod.h and use c_strtod.  Don't include stdlib.h; no
        longer needed.

2004-01-14  Paul Eggert  <eggert@twinsun.com>

        * fnmatch_loop.c (ALLOCA_LIMIT): Remove macro, which collided
        with like-named macro in fnmatch.c.
        (EXT): Use an internal constant instead.

        Merge fnmatch patches from glibc.
        * fnmatch.c (mbsinit): Remove define.
        Add libc_hidden_ver (__fnmatch, fnmatch).
        * fnmatch_loop.c (FCT): Cast to int32_t and UCHAR when appropriate.
        Adjust to renaming of collseq_table_lookup to __collseq_table_lookup.

2003-12-14  Karl Berry  <karl@gnu.org>

        * config.charset: update from gettext-runtime.

2003-12-03  Paul Eggert  <eggert@twinsun.com>

        * getgroups.c (getgroups): xmalloc takes one argument, not two.
        Bug reported by Alfred M. Szmidt.

2003-11-29  Karl Berry  <karl@gnu.org>

        * argp-{help.c,parse.c,namefrob.h}, argp.h: update from libc.

2003-11-23  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        * printf-parse.h: Don't include sys/types.h.
        (ARG_NONE): New macro.
        (char_directive): Change type of *arg_index fields to size_t.
        * printf-parse.c: Don't include sys/types.h.
        (SSIZE_MAX): Remove macro.
        (PRINTF_PARSE): Change the type of the arg_index variables to size_t.
        Remove unnecessary overflow check.
        * vasnprintf.c (VASNPRINTF): Update for type change of *arg_index
        fields.

2003-11-24  Paul Eggert  <eggert@twinsun.com>

        * alloca.c: Remove dependency on xalloc module.
        (xalloc_die): Remove.
        (memory_full) [!defined emacs]: New macro.
        [!defined emacs]: Don't include xalloc.h.
        (alloca): Invoke memory_full, not xalloc_die, if malloc fails or
        address arithmetic overflows.  Change datatypes a bit to avoid
        unnecessary casts.

2003-11-22  Jim Meyering  <jim@meyering.net>

        * xmalloc.c (x2nrealloc_inline): Fix typos in comments: s/size/size_t/.

2003-11-17  Bruno Haible  <bruno@clisp.org>

        * vasnprintf.c (alloca): Remove fallback definition.
        (freea): Remove definition.
        (VASNPRINTF): Use alloca only for small sizes, say <= 4000 bytes.
        Reported by Paul Eggert.

2003-11-17  Jim Meyering  <jim@meyering.net>

        On systems without utime and without a utimes function capable of
        dealing with a NULL struct utimbuf* argument, this utime replacement
        could -- in unusual circumstances -- leak a file descriptor.
        * utime.c: Include <unistd.h> and <errno.h>.
        (utime_null): Be sure to close `fd' and to preserve errno.
        Reported by Geoff Collyer via Arnold Robbins.

2003-11-16  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        Protect against address arithmetic overflow.
        * printf-args.h: Include stddef.h.
        (arguments): Change type of field 'count' to size_t.
        * printf-args.c (printf_fetchargs): Use size_t instead of
        'unsigned int' where appropriate.
        * printf-parse.h: Include sys/types.h.
        (char_directive): Change type of *arg_index fields to ssize_t.
        (char_directives): Change type of fields 'count', max_*_length to
        size_t.
        * printf-parse.c: Include sys/types.h and xsize.h.
        (SSIZE_MAX): Define fallback value.
        (PRINTF_PARSE): Use size_t instead of 'unsigned int' and ssize_t
        instead of 'int' where appropriate. Check a_allocated, d_allocated
        against overflow. Reject %m$ argument numbers > SSIZE_MAX + 1.
        * vasnprintf.c: Include xsize.h.
        (VASNPRINTF): Use size_t instead of 'unsigned int' where appropriate.
        Check alloca, malloc, realloc, ENSURE_ALLOCATION arguments against
        overflow. Avoid wraparound when converting a width or precision from
        decimal to binary.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        Update from GNU gettext.
        * printf-parse.c: Generalize to it can be compiled for wide strings.
        (PRINTF_PARSE, CHAR_T, DIRECTIVE, DIRECTIVES): New macros.
        * vasnprintf.c: Generalize to it can be compiled for wide strings.
        (VASNPRINTF, CHAR_T, DIRECTIVE, DIRECTIVES, PRINTF_PARSE, USE_SNPRINTF,
        SNPRINTF): New macros.
        Don't include <alloca.h> if the file is used inside libintl.
        (local_wcslen): New function, for Solaris 2.5.1.
        (VASNPRINTF): Use it instead of wcslen.

2003-11-16  Bruno Haible  <bruno@clisp.org>

        * xsize.h (xmax): New function.
        (xsum, xsum3, xsum4): Declare as "pure" functions.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h: Do not include <limits.h> or <stdint.h>.
        (xalloc_oversized): Use sizeof (ptrdiff_t) and sizeof (size_t) for
        the heuristic, rather than PTRDIFF_MAX and SIZE_MAX.  This
        heuristic is just as accurate as far as we know, and it removes a
        dependency on size_max.m4 and ptrdiff_max.m4.

2003-11-12  Paul Eggert  <eggert@twinsun.com>

        * xstrtol.c (__xstrtol): Remove "break" immediately after
        "return", to pacify some unknown compiler.  Problem reported
        by Joerg Schilling.

2003-11-11  Bruno Haible  <bruno@clisp.org>

        * xsize.h (SIZE_MAX): Remove fallback definition.
        * xalloc.h: Include limits.h. Assume SIZE_MAX and PTRDIFF_MAX are
        defined.

2003-11-10  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h (xalloc_oversized): [! (defined PTRDIFF_MAX &&
        PTRDIFF_MAX < SIZE_MAX)]: Fix off-by-one error that would have
        rejected some allocations of exactly SIZE_MAX - 2 bytes.
        From Bruno Haible.
        [defined PTRDIFF_MAX && PTRDIFF_MAX < SIZE_MAX]: Use SIZE_MAX,
        not (size_t) -1, since it's defined here.

2003-11-06  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h [HAVE_STDINT_H]: Include <stdint.h>.
        (xalloc_oversized) [! (PTRDIFF_MAX < SIZE_MAX)]:
        Reject sizes of exactly SIZE_MAX bytes.
        * xreadlink.c: Include "xalloc.h" before checking whether SIZE_MAX
        is defined, since "xalloc.h" now defines SIZE_MAX on modern hosts.

2003-11-05  Bruno Haible  <bruno@clisp.org>

        * xsize.h: Include limits.h, to avoid a possible collision with
        SIZE_MAX defined in <limits.h> on Solaris.

2003-11-04  Bruno Haible  <bruno@clisp.org>

        * xsize.h: New file.
        * linebreak.c: Include xsize.h.
        (mbs_possible_linebreaks, mbs_width_linebreaks): Check malloc()
        argument for overflow.
        Suggested by Paul Eggert.

2003-10-31  Bruno Haible  <bruno@clisp.org>

        * wait-process.c (wait_process): Use waitid with WNOWAIT if available,
        to avoid (extremely rare) race condition.
        Suggested by Paul Eggert.

2003-11-03  Jim Meyering  <jim@meyering.net>

        * userspec.c: Include "userspec.h".
        * userspec.h: New file.

2003-10-31  Paul Eggert  <eggert@twinsun.com>

        * mountlist.h (struct mount_entry.me_type_malloced): New member.
        * mountlist.c (SIZE_MAX): Define if not defined already.
        (read_filesystem_list): Set and use me_type_malloced.
        Use "sizeof *me" rather than "sizeof (struct mount_entry)" (or
        whatever the type happens to be), for brevity and consistency.
        Check for size calculation overflow on Alphas running OSF/1.

2003-10-31  Jim Meyering  <jim@meyering.net>

        * hash.c: Include "xalloc.h" for use of xalloc_oversized.

        * linebuffer.c: Include <string.h> for declaration of memset.

2003-10-30  Paul Eggert  <eggert@twinsun.com>
            Bruno Haible  <bruno@clisp.org>

        * vasprintf.c: Include <limits.h>, <stdlib.h>.
        (vasprintf): Fail if the resulting length doesn't fit in an 'int'.

2003-10-29  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h (xalloc_oversized): Now a macro, not a function,
        so that it works even if SIZE_MAX < N.  Do not include <stdbool.h>;
        no longer needed.
        * quotearg.c (quotearg_n_options): Use it.
        * group-member.c: Include <stdbool.h>.
        (free_group_info): Arg is now const *; don't free arg.
        (get_group_info): Now returns bool and accepts struct group_info *,
        rather than returning a malloc'ed struct group_info *.
        All uses changed.  Check for overflow in internal size calculation.

        * getusershell.c (readname): Simplify the code by using x2nrealloc
        rather than xmalloc/xrealloc.
        * linebuffer.c (initbuffer, readlinebuffer): Simplify the code by
        using x2realloc rather than xmalloc/xrealloc.  Also, fix a C
        conformance bug: the old code used a pointer after freeing the
        storage that it addressed.
        * hash.c (hash_initialize): Simplify the code by using xalloc_oversized
        rather than doing it by hand.
        * getgroups.c (getgroups): Don't use xrealloc, since we don't need
        the buffer preserved.  Use free and xmalloc instead.
        * quotearg.c (quotearg_n_options): Likewise.
        Use a simpler test for size overflow.  Don't use xalloc_oversized
        because unsigned int might be wider than size_t (!); this suggests
        that we should switch from unsigned int to size_t for slot numbers.

2003-10-27  Bruno Haible  <bruno@clisp.org>

        * stdbool_.h: Better support for BeOS.

2003-10-27  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (new_exclude): Use xzalloc rather than xmalloc
        to allocate the returned structure.  Do not allocate a subarray,
        as x2nrealloc will do that.
        (add_exclude): Use x2nrealloc to reallocate ex->exclude,
        instead of xnrealloc.
        (add_exclude_file): Use x2realloc instead of malloc + xnrealloc.

2003-10-26  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h (xalloc_oversized): New static inline function, for
        callers that want to do their own size-overflow checking.  Include
        <stdbool.h>, since xalloc_oversized returns bool.
        * xalloc.c (array_size_overflow): Remove.  All callers changed
        to use xalloc_oversized.

        Add two functions x2realloc, x2nrealloc, for programs that grow
        arrays dynamically by doubling their sizes.
        * xalloc.h (x2realloc, x2nrealloc): New decls.
        * xmalloc.c (x2nrealloc_inline, x2nrealloc, x2realloc):
        New functions.

        Port to C99 semantics for 'inline' of external functions.
        Bug reported by Bruno Haible.
        * xmalloc.c (xnmalloc_inline): New static inline function,
        with the old contents of xnmalloc.
        (xnmalloc, xmalloc): Use it.
        (xnrealloc_inline): New static inline function,
        with the old contents of xnrealloc.
        (xnrealloc, xrealloc): Use it.

        * alloc.c (alloca): xmalloc cannot return NULL, so don't test for that.

2003-10-25  Paul Eggert  <eggert@twinsun.com>

        Fix several address-calculation bugs in the hash modules,
        plus some minor code cleanup.

        * hash.h: Include <stdbool.h>, for bool.
        * hash.c: Don't include <stdbool.h>, since hash.h does it now.
        * hash.h (Hash_hasher, hash_get_n_buckets, hash_get_n_buckets_used,
        hash_get_n_entries, hash_get_max_bucket_length,
        hash_get_entries, hash_do_for_each, hash_string, hash_initialize,
        hash_rehash): Use size_t rather than unsigned.
        * hash.c (struct hash_table, hash_get_n_buckets,
        hash_get_n_buckets_used, hash_get_n_entries,
        hash_get_max_bucket_length, hash_table_ok, hash_print_statistics,
        hash_get_entries, hash_do_for_each, hash_string, is_prime,
        next_prime, hash_initialize, hash_rehash, hash_delete, hash_print):
        Likewise.
        (SIZE_MAX): Define if not defined.
        (hash_get_max_bucket_length, hash_table_ok, hash_lookup,
        hash_get_first, hash_get_next, hash_get_entries, hash_do_for_each,
        hash_print):
        Use const * when possible.
        (hash_string): Use (unsigned char) *P rather than *(unsigned char *) P.
        (check_tuning): Fix bug: if tuning parameters were very close to
        0 or 1, rounding errors could have caused subscript violations.
        (hash_initialize, allocate_entry, hash_print): Remove unnecessary cast.
        (hash_initialize): Add 'fail:' label
        to free table and return NULL, and use it to simplify code.
        Use calloc rather than clearing the storage ourself.
        (hash_initialize, hash_rehash): Check for arithmetic overflow in
        buffer size calculations.
        * hash-pjw.h (hash_pjw): Use size_t, not unsigned.
        Include <stddef.h>, for size_t.
        * hash-pjw.c (hash_pjw): Likewise.
        Switch to method described by Bruno Haible.
        Include <limits.h>, for CHAR_BIT.
        (SIZE_BITS): New macro.

2003-10-21  Paul Eggert  <eggert@twinsun.com>

        * getndelim2.c (getndelim2): When size calculation overflows,
        ceiling the allocation at NMAX bytes rather than silently
        discarding input bytes before NMAX is reached.  This makes
        a difference only if NMAX exceeds SIZE_MAX / 2.

        * obstack.c: Merge from glibc.
        [defined _LIBC]: Include <obstack.h>, not "obstack.h".
        Add libc_hidden_def (_obstack_newchunk).
        (_obstack_free) [! defined _LIBC]: Remove.
        [defined _LIBC]: Make a strong alias from obstack_free, rather than
        a clone of the function body.
        (fputs) [defined _LIBC && defined USE_IN_LIBIO]: Remove.
        [defined _LIBC && !defined USE_IN_LIBIO]: Include <libio/iolibio.h>.

        * obstack.h: Indenting cleanup, to make it easier to merge with glibc.
        (obstack_grow, obstack_grow0): Remove unnecessary parentheses around
        arg to memcpy.

        * obstack.h (obstack_1grow_fast): Properly parenthesize arg.
        (obstack_ptr_grow_fast, obstack_int_grow_fast):
        Don't use lvalue casts, as GCC plans to remove support for them
        in GCC 3.5.  Reported by Joseph S. Myers.  This bug
        was also present in the non-GCC version, indicating that this
        code had always been buggy and had never been widely used.
        (obstack_1grow, obstack_ptr_grow, obstack_int_grow, obstack_blank):
        Use the fast variant of each macro, rather than copying the
        definiens of the fast variant; that way, we'll be more likely to
        catch future bugs in the fast variants.

2003-10-20  Bruno Haible  <bruno@clisp.org>

        * wait-process.h: New file, from GNU gettext.
        * wait-process.c: New file, from GNU gettext.

2003-10-19  Jim Meyering  <jim@meyering.net>

        * vasnprintf.c (vasnprintf): Work around losing snprintf on HPUX 10.20.

2003-10-16  Paul Eggert  <eggert@twinsun.com>

        * getgroups.c: Include <errno.h>, <stdlib.h>.
        (getgroups): First arg is int, not size_t.
        Don't let 'free' mangle errno.

2003-10-16  Jim Meyering  <jim@meyering.net>

        * xmalloc.c: Include <string.h>, for declarations of memset and memcpy.

2003-10-15  Paul Eggert  <eggert@twinsun.com>

        * exclude.c: Do not include <inttypes.h> or <stdint.h>.
        (SIZE_MAX): Remove.
        (new_exclude, add_exclude_file): Initial size no longer needs to
        be a power of 2.
        (add_exclude, add_exclude_file): Use xnrealloc instead of rolling
        our own address arithmetic overflow checking.

        * fnmatch.c (SIZE_MAX): Define if standard headers don't.
        (fnmatch): Do not alloca more than 2000 wide characters;
        instead, use malloc for large buffers.
        Check for address arithmetic overflow, and return -1
        with errno set to ENOMEM in that case.
        * fnmatch_loop.c (ALLOCA_LIMIT): New macro.
        (NEW_PATTERN): Do not alloca more than 8000 bytes;
        instead, return -1.  Check for address arithmetic overflow.

2003-10-14  Paul Eggert  <eggert@twinsun.com>

        Handle invalid suffixes and overflow independently, so that
        callers can treat them independently as needed.  Fix some bugs in
        suffix handling, e.g., "100k@" was not diagnosed as an invalid
        suffix for a human-readable blocksize.  The major caller-visible
        change is the addition of a new
        LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW enum value, indicating
        that both overflow and suffix chars were found.

        * human.c (humblock): Don't check separately for invalid suffix
        char; that is xstrtoumax's job (now that its bug is fixed).
        * xstrtoimax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM) [defined
        INTMAX_MAX]: New macros.
        * xstrtol.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM, TYPE_MINIMUM,
        TYPE_MAXIMUM): New macros.
        (bkm_scale, bkm_scale_by_power): Return strtol_error, not int.
        (bkm_scale, bkm_scale_by_power, __xstrtol): Return maximal values
        if overflow occurs, as it's what __strtol does and it's more useful
        in practice.
        (__xstrtol): If __strtol reports some error other than ERANGE,
        reflect it to the caller as LONGINT_INVALID.  If it reports
        ERANGE, continue the rest of parsing, and report LONGINT_OVERFLOW
        | LONGINT_INVALID_SUFFIX_CHAR if both errors occur.
        * xstrtol.h (LONGINT_INVALID_SUFFIX_CHAR_WITH_OVERFLOW): New enum
        value.
        (_STRTOL_ERROR): Handle it.  Abort when given unknown error codes.
        * xstrtoul.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM): New macros.
        * xstrtoumax.c (STRTOL_T_MINIMUM, STRTOL_T_MAXIMUM)
        [defined UINTMAX_MAX]: New macros.

2003-10-14  Bruno Haible  <bruno@clisp.org>

        * fatal-signal.h: Improved comments. Suggested by Paul Eggert.
        * fatal-signal.c: Use sig_atomic_t. Suggested by Paul Eggert.
        Also use volatile where needed.

2003-10-12  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h (xnmalloc, xzalloc, xnrealloc, xclone): New decls.
        (XMALLOC, XCALLOC, XREALLOC, XFREE, CCLONE, CLONE): Deprecate,
        and define in terms of the other primitives.
        * xmalloc.c: Include stdbool.h; do not include exit.h.
        (SIZE_MAX): Define if not already defined.
        (array_size_overflow): New function.
        (xalloc_die): Abort instead of exiting if 'error' returns.
        (xnmalloc, xnrealloc, xzalloc, xclone): New functions.
        (xmalloc, xrealloc): Use them.
        (xcalloc): Check for address arithmetic overflow.
        * xstrdup.c (xstrdup): Use xclone, since memcpy should be
        a bit faster than strcpy.

2003-10-08  Paul Eggert  <eggert@twinsun.com>

        Merge getpass from libc, plus a few fixes.

        * getpass.c (HAVE_STDIO_EXT) [_LIBC]: Define to 1.
        Include <stdbool.h>.
        Include <stdio_ext.h> if HAVE_STDIO_H, otherwise define
        __fsetlocking to empty.
        [_LIBC]: Do not include "getline.h" or "unlocked-io.h", but
        do include <bits/libc-lock.h>.
        Do not include <fcntl.h>; not needed.
        [_LIBC]: Include <wchar.h>.
        (NOTCANCEL_MODE): New macro.
        (flockfile, funlockfile) [_LIBC]: New macros.
        (__libc_cleanup_push, __libc_cleanup_pop, __getline, __tcgetattr)
        [!_LIBC]: New macros.
        (call_fclose): New function.
        (getpass): Use it.  Save tty stream separately; this simplifies the
        code and makes it more reliable if stdin happens to equal stdout.
        Invoke __fsetlocking on tty.
        Handle thread cancellation if needed.
        Namespace cleanup (use __tcgetattr, __getline).
        Use bool for Booleans.
        [USE_IN_LIBIO]: Handle wide streams.
        [!_LIBC]: Unconditionally do the fseek, since we don't know what
        stream might go where.

        * unlocked-io.h: Include <stdio.h>, so that the caller
        doesn't have to include <stdio.h> before us.
        (clearerr_unlocked, feof_unlocked, ferror_unlocked,
        fflush_unlocked, fgets_unlocked, fputc_unlocked, fputs_unlocked,
        fread_unlocked, fwrite_unlocked, getc_unlocked, getchar_unlocked,
        putc_unlocked, putchar_unlocked): Define to the unlocked counterpart
        if not declared, so that we can use getpass.c code from libc without
        rewriting it.
        (flockfile, ftrylockfile, funlockfile): New macros.

2003-10-06  Bruno Haible  <bruno@clisp.org>

        * version-etc-2.h: Remove file.

            Bruno Haible  <bruno@clisp.org>

        This lets translators provide better translations for the
        "Written by ..." part of --version output.
        * version-etc.h: Include stdarg.h.
        (version_etc_copyright): Declare as readonly.
        (version_etc): Make this function variadic with a NULL-terminated list
        of author name strings.
        (version_etc_va): New declaration.
        * version-etc.c: Include stdarg.h, stdlib.h.
        (version_etc_copyright): Declare as readonly.
        (version_etc_va): New function. Provide a different translatable string
        for each possible number of authors < 10. Abbreviate when there are 10
        authors or more.
        (version_etc): Make this function variadic. Call version_etc_va.
        Suggestion from Gary V. Vaughan.

        * long-options.h (parse_long_options): Change prototype: the authors
        string is moved to the end and becomes variadic.
        * long-options.c: Include stdarg.h.
        (parse_long_options): Make this function variadic, too.
        Call version_etc_va, not version_etc.

2003-10-06  Bruno Haible  <bruno@clisp.org>

        * argp*: update from libc.

2003-10-01  Larry Jones  <lawrence.jones@eds.com>

        * getpass.c (getpass): Use a no-op fseek when switching from input to
        output mode on the same stream.

2003-09-29  Paul Eggert  <eggert@twinsun.com>

        * strftime.c (tm_diff) [! HAVE_TM_GMTOFF]:
        Fix arg typo in previous patch.

2003-09-28  Jim Meyering  <jim@meyering.net>

        * error.c: Correct cpp indentation.

2003-09-27  Paul Eggert  <eggert@twinsun.com>

        * minmax.h (MIN, MAX) [__STDC__ && defined __GNUC__ && __GNUC__ >= 2]:
        Omit the special code that used __typeof__, since we worry that
        it could be more trouble than it's worth.  See:
        http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00090.html
        http://mail.gnu.org/archive/html/bug-gnulib/2003-01/msg00095.html

        * free.c: New file.

        into inner scope where the local variables are used.

2003-09-26  Bruno Haible  <bruno@clisp.org>

        * stpncpy.h (gnu_stpncpy): New declaration.
        (stpncpy): Define as alias for gnu_stpncpy.
        * stpncpy.c [!_LIBC]: Define gnu_stpncpy, not stpncpy.

2003-09-26  Paul Eggert  <eggert@twinsun.com>

        * error.c (SIZE_MAX) [!defined SIZE_MAX]: Define.
        (error_tail): Do not loop, reallocating temporary buffer, since
        the output cannot contain more wide characters than the input
        contains bytes, the size must be big enough already.  This avoids
        one potential size overflow calculation.  Check for size overflow
        when calculating temporary buffer size.  Free temporary buffer
        when done, if it was allocated with malloc; this plugs a memory
        leak.  Remove casts from void * to pointers, that are no longer
        needed now that we're assuming C89 or better.

        Merge error changes from glibc.

        * error.c, error.h: Update copyright notice header to match glibc.
        * error.c [defined _LIBC]: Include <errno.h>, <bits/libc-lock.h>.
        (error, error_at_line) [defined _LIBC && defined __libc_ptf_call]:
        Disable cancellation while printing error.
        * error.h: Prepend __ to parameter names.

2003-09-25  Karl Berry  <karl@gnu.org>

        * argp-fmtstream.c, argp-help.c: update from libc.

2003-09-24  Paul Eggert  <eggert@twinsun.com>

        * linebuffer.c (freebuffer): Don't free the argument, just

        * argp.h: update from libc.

2003-09-16  Paul Eggert  <eggert@twinsun.com>

        * linebuffer.c (readlinebuffer): Return NULL immediately upon
        input error, instead of returning NULL the next time we are called
        (and therefore losing track of errno).

2003-09-15  Paul Eggert  <eggert@twinsun.com>

        * getndelim2.c (getndelim2): Don't trash errno when a read
        fails, so that the caller gets the proper errno.

        * readutmp.c (read_utmp): Likewise.
        Check for fstat error.  Close stream and free storage
        when failing.

2003-09-14  Bruno Haible  <bruno@clisp.org>

        * fwriteerror.h: New file.

2003-09-08  Paul Eggert  <eggert@twinsun.com>

        * getversion.c: Remove; was migrated to backupfile.c in 1997.
        getversion.c should have been removed then, but was accidentally

        * time_r.c (gmtime_r, localtime_r): Fix silly typo: missing arg to
        copy_tm_result.  Bug reported by Simon Josefsson in
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-09/msg00028.html>.

        (timegm): Use a prototype, since gnulib assumes C89.
        Do not bother declaring tmp to be const, as it's not really usefu.
        * timegm.h: Hoist "#include <time.h>" out of #ifdef.
        (timegm): Declare only if HAVE_DECL_TIMEGM.

2003-09-03  Paul Eggert  <eggert@twinsun.com>

        * human.c (human_readable): Fix bug that rounded 10501 to 10k.
        Bug reported by Lute Kamstra in
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-09/msg00003.html>.

        * getdate.y (relative_time_table): Use tDAY_UNIT for "tomorrow",
        "yesterday", "today", and "now" rather than tMINUTE_UNIT.  Of
        course with correspondingly smaller numbers for tomorrow and
        yesterday.  From Tadayoshi Funaba.  Originally installed into
        sh-utils on 1999-08-07, but the patch got lost (I guess during the
        coreutils merge?).

2003-08-31  Simon Josefsson  <jas@extundo.com>

2003-08-24  Bruno Haible  <bruno@clisp.org>

        * binary-io.h: Include <stdio.h>, to avoid a compilation error when
        MSVC7 <stdio.h> is included later.

2003-08-20  Bruno Haible  <bruno@clisp.org>

        * progname.h: New file, from GNU gettext.
        * progname.c: New file, from GNU gettext.

2003-08-16  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * xstrtoimax.c: #else #if -> #elif.
        * xstrtoumax.c: Likewise.

2003-08-15  Paul Eggert  <eggert@twinsun.com>

        * config.charset, ref-add.sin, ref-del.sin: Use three spaces,
        rather than tab, after '#' in shell-script copyright notices.
        Suggested by Bruno Haible.

2003-08-15  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merge from coreutils.
        * readutmp.h (HAVE_UTMPX_H): Undef if struct utmp has the ut_exit
        member but strut utmpx does not.  Needed for AIX 4.3.3.
        (UT_EXIT_E_TERMINATION, UT_EXIT_E_EXIT): Define.

2003-08-15  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * xgethostname.c: Include <stdlib.h>.
        (xghostname): Don't exit for anything other than memory-related
        failure; just return NULL.
        * userspec.c: Include "posixver.h".
        (parse_user_spec): Accept `.' as a separator only
        in pre-POSIX-200112 mode.
        * strtoimax.c: Use #elif rather than #else #if.
        * strftime.c (my_strftime) [!_LIBC && HAVE_TZNAME && HAVE_TZSET]:
        Remove function, now that we can rely on a working tzset function.
        [!_LIBC]: Ensure that the required autoconf test has been run.
        [!defined _NL_CURRENT && HAVE_STRFTIME]:
        Use underlying_strftime for %r.
        * sha.c: Merge in some clean-up and optimization changes from glibc.
        * sha.c (sha_stream) [BLOCKSIZE]: Move definition to top of file.
        Ensure that it is a multiple of 64.
        Rearrange loop exit tests so as to avoid performing an
        additional fread after encountering an error or EOF.
        * realloc.c: Update copyright date.

2003-08-14  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * obstack.h: Whitespace changes.
        * mountlist.c: Remove anachronistic casts of xmalloc, xrealloc,
        and xcalloc return values.
        (read_filesystem_list) [MOUNTED_GETFSSTAT]:
        Use MNT_NOWAIT, rather than MNT_WAIT.  Otherwise, `df DIR' could
        hang on OSF/1 5.1 for DIR on both local and remote file systems.
        Reported by (and fix confirmed by) Nelson H. F. Beebe.
        (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

2003-08-14  Jim Meyering  <jim@meyering.net>
        and Paul Eggert  <eggert@twinsun.com>

        Merges from coreutils, plus other fixes.
        * physmem.c: Merge in portability changes from gcc/libiberty
        to support AIX, IRIX, Tru64, and Windows.  See the ChangeLog there

        additional fread after encountering an error or EOF.
        * md5.h (md5_uintptr): Define.
        * makepath.c (CLEANUP_CWD): Report an error if we failed to
        return to the initial working directory.  Preserve errno
        for caller.

        (vasnprintf): Use it instead of wcslen.

2003-08-11  Bruno Haible  <bruno@clisp.org>

        * stdbool_.h (_Bool): Undo last change; instead use a negative enum
        value to ensure that _Bool promotes to int. Use #define for _Bool when
        using the Solaris C compiler. Adds comments suggested by Paul Eggert.

2003-08-10  Karl Berry  <karl@gnu.org>

        * regex.h: update from libc (whitespace fix).

2003-08-09  Paul Eggert  <eggert@twinsun.com>

        Merge some files from coreutils.  These changes were
        originally made by Jim Meyering.
        * acl.c: Include <sys/types.h> before <sys/stat.h>;
        many older Unixes require this.
        * alloca.c (alloca): Remove cast to argument of free;
        no longer needed in C89.
        * alloca_.h, regex.h: Fix white space to match
        what GNU indent does.

2003-08-05  Paul Eggert  <eggert@twinsun.com>

        from Dmitry V. Levin.
        Remove anachronistic cast of xrealloc.
        * fnmatch_.h (__const): Remove.  Use 'const'.
        * fnmatch_loop.c (NEW_PATTERN): Cast alloca return value to proper
        type. Otherwise, it wouldn't compile with at least /bin/cc on
        ymp-cray-unicos9.0.2.X.
        Combine two mostly-identical uses of alloca into one.
        Thanks to the Cray-Cyber project for access to a Cray Y-MP.

2003-08-04  Dave Love <d.love@dl.ac.uk>

        [From Emacs.]

        * getloadavg.c: Check `__unix' as well as `unix'.  Use #ifdef, not
        #if.  Check HAVE_LIBKSTAT as well as LOAD_AVE_TYPE.  Check
        F_SETFD, not FD_SETFD.  Use HAVE_STRUCT_NLIST_N_UN_N_NAME, not
        obsolete NLIST_NAME_UNION.
        [__GNU__]: Undef BSD and FSCALE.
        [!NLIST_STRUCT]: Remove conditional definition of NLIST_STRUCT.

2003-08-03  Paul Eggert  <eggert@twinsun.com>

        * stdbool_.h (_Bool): Make it signed char, instead of
        an enum type, so that it's guaranteed to promote to int.  See:
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-07/msg00124.html>

2003-07-31  Paul Eggert  <eggert@twinsun.com>

        * strerror.c: Include config.h, limits.h.  Declare sprintf.
        (strerror): Don't assume that a printable int fits in 14 bytes.

2003-07-24  Derek Robert Price  <derek@ximbiot.com>
            Bruno Haible  <bruno@clisp.org>

        * getline.h (getline, getdelim): Change return type to ssize_t.
        * getline.c (getline, getdelim): Likewise.
        Remove _GNU_SOURCE define; now it's defined in config.h through
        m4/getline.m4.

2003-07-22  Paul Eggert  <eggert@twinsun.com>

        * xalloc.h (XCALLOC, XREALLOC, CCLONE): Fix under- and
        over-parenthesization in macros.

        Sync with coreutils.

        * xalloc.h (XMALLOC, XCALLOC, XREALLOC): Remove casts not
        required by C99.

        Use `exit_failure' for xalloc and xmemcoll instead of their own
        private exit-failure variables.
        * xalloc.h (xalloc_exit_failure): Remove.
        * xmalloc.c: Likewise.  Include exitfail.h.

        (xmemcoll): Use exit_failure instead of xalloc_exit_failure.

2003-07-18  Paul Eggert  <eggert@twinsun.com>

        * closeout.h (close_stdout_set_status, close_stdout_status): Remove.
        * closeout.c: Likewise.  Include "closeout.h" right after config.h,
        to test that it can stand by itself.  Include "exitfail.h".
        Clients should set exit_failure instead.
        (EXIT_FAILURE): Remove; no longer needed.  Do not include <stdlib.h>.

2003-07-18  Andreas Schwab  <schwab@suse.de>

        * memcoll.c (memcoll) [!HAVE_STRCOLL]: Clear errno.

        (getndelim2): Make non-static. Change return type to ssize_t.
        * getline.h: Change argument names.

        ref-del.sin, setenv.c, unsetenv.c, vasnprintf.c, vasnprintf.h,
        vasprintf.c, vasprintf.h: Regenerate.  These files are now being
        updated automatically by ../config/srclist-update.  This changes
        their license from LPGL to GPL.

2003-07-14  Jim Meyering  <jim@meyering.net>

        Don't emit diagnostics.  Let callers do that.
        * save-cwd.c: Don't include "error.h".
        (save_cwd): Don't call error.  Ensure that errno is valid
        when returning nonzero.

        * save-cwd.h (restore_cwd): Update prototype.
        * save-cwd.c (restore_cwd): Remove two parameters.
        Simplify.  Don't call error upon failure.  Let callers do that.
        (save_cwd): Mention that Irix 5.3 has the same problem as SunOS 4
        when auditing is enabled.  But don't bother updating the #if.

2003-07-14  Simon Josefsson  <jas@extundo.com>

        * mempcpy.h: New file.
        * mempcpy.c: New file.

        unicodeio.c, unicodeio.h, unlocked-io.h:
        Switch from LGPL to GPL.

2003-07-11  Alexandre Duret-Lutz  <adl@gnu.org>

        * obstack.h (__INT_TO_PTR): Revert change of 2003-03-13;
        it breaks C++ compilation.
        [!__GNUC__ || !__STDC__] (obstack_finish): Cast result to void*.

2003-07-10  Jim Meyering  <jim@meyering.net>

        * vasnprintf.c: Remove trailing blanks.
        Make cpp indentation consistent.

2003-07-09  Paul Eggert  <eggert@twinsun.com>

        * alloca_.h, euidaccess.c, getpass.c, memrchr.c, obstack.h,
        posixver.c, strftime.c, strnlen.c, strverscmp.c:
        Switch from LGPL to GPL.

2003-07-07  Paul Eggert  <eggert@twinsun.com>

        * mktime.c: Fix some boundary cases and remove need for floating point.

        Issue a compile-time diagnostic if time_t is floating point, or if
        two's complement arithmetic is not in effect, or if arithmetic
        right shift does not propagate the sign.  These assumptions were
        all in the original code but they weren't checked.

        (TIME_T_MIDPOINT, verify): New macros.
        (__isleap): Remove; it has integer overflow problems.
        (leapyear): New function, without those problems.
        (ydhms_tm_diff): Remove; splitting into two parts.
        (ydhms_diff): New function, containing the arithmetic part of
        the old ydhms_tm_diff function.  Issue a compile-time
        diagnostic if we are not using C99 integer division.
        Avoid casts when possible.
        (guess_time_tm): New function, containing the checking part of
        the old ydhms_tm_diff function.  Return the new value, rather than
        the difference between it and the old.  Accept a new argument T
        so that *T specifies the old value.  Check for overflow in the result.

        (__mktime_internal): Use a time_t offset, not a long int offset.
        This undoes the 2003-06-04 change, which is no longer needed now
        that we have better overflow checking.
        (localtime_offset): Likewise.

        (__mktime_internal): Avoid harmful overflow on hosts where time_t
        and long are 64-bit but int is only 32-bit.
        (ydhms_diff): Use long int to store year1 and yday1.
        Issue a compile-time diagnostic if long int is not wide enough.

        (__mktime_internal): Use long int to store adjusted year and yday.
        Use plain C rather than preprocessor commands, if that doesn't
        affect efficiency.
        Check for overflow (and try to repair) after each probe
        rather than checking only at the very end.  This avoids some bugs
        (e.g., southern hemisphere, behind GMT, and GMT offset at minimum time
        does not equal GMT offset at maximum time).
        Use integer to check for overflow rather than floating point; this
        is more portable to non-IEEE hosts, and is a tad faster.
        When we detect that we are oscillating between two values,
        don't check whether tm_isdst has the requested value, since
        we already know the answer.  When tm_isdst has the wrong value,
        use a different heuristic to find the right one, based on the
        extreme values actually observed in practice in tz2003a,
        rather than the (overly optimistic) "previous 3 calendar quarters".

        (not_equal_tm, print_tm, check_result): Use "const T" rather than
        "T const" to accommodate glibc style.
        (check_result): Use less-confusing report format.  "long" -> "long int.
        (main): Likewise.
        Don't loop if the iteration overflows time_t.
        Allow a negative step in the iteration.

2003-07-01  Paul Eggert  <eggert@twinsun.com>

        * xreadlink.c: Include <sys/types.h> unconditionally, instead of
        having it depend on HAVE_SYS_TYPES_H.

2003-06-25  Bruno Haible  <bruno@clisp.org>

        * readlink.c: New file.

2003-06-20  Bruno Haible  <bruno@clisp.org>

        * filemode.h, hard-locale.h, memcoll.h, modechange.h, physmem.h,
        same.h, strverscmp.h: Do not include config.h; no longer needed.
        Anyway, config.h should always be included before any other file.

        in place of my name in the copyright comment.
        Remove definition and uses of __P.

        From coreutils.
        * stat.c: Don't declare xmalloc explicitly.

        Consolidate declarations and initializations of *_base* locals.

        Merge from coreutils.
        This avoids a core dump on systems without GNU putenv,
        when running `env -u SOME_ALREADY_UNSET_VARIABLE'.
        * putenv.c (__set_errno, LOCK, UNLOCK): Define.
        (unsetenv): New static function, from GNU libc.
        (rpl_putenv): Use it.

        * modechange.c: Remove trailing blanks.

        Merge from coreutils.

2003-06-05  Paul Eggert  <eggert@twinsun.com>

        * mktime.c (__mktime_internal): When resolving a tm_isdst
        mismatch, look in future quarters as well as past.  This fixes a
        bug when processing fall-backwards gaps immediately after a long
        period of daylight-saving time.

        * mktime.c: Assume freestanding C89 or better.
        (HAVE_LIMITS_H): Remove.  Assume it's 1.

        <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=177940>.
        (localtime_offset): Now long int, not time_t, because we want it
        to be guaranteed to be signed.  All uses changed.
        (__mktime_internal): If overflow would occur when adding offset,
        don't add it.

        Merge 'human' changes from coreutils.  Rewrite to support
        locale-specific notations like thousands separators.
        * human.c: Simplify authorship notice.

        and long double value (for greater precision on some platforms).
        (group_number): New function.
        (human_readable): Use it.  Use integer options, not enum.
        Put the options before the sizes in the arg list.
        Support all the new options.
        The old human_readable function has been removed;
        use inttostr.h instead.
        (human_readable, default_block_size, humblock):
        Use uintmax_t, not int, for block sizes.
        (human_readable_inexact, block_size_types): Remove.
        (block_size_opts): New constant.
        (human_options): Renamed from human_block_size, with new signature
        that allows block sizes up to UINTMAX_MAX.  All callers changed.
        * human.h: Add copyright and authorship notice.
        Include <limits.h> and <stdbool.h> unconditionally.
        (PARAMS): Remove.  All uses removed.
        (LONGEST_HUMAN_READABLE): Add support for thousands separator.
        (enum human_inexact_style): Remove tag; now a nameless enum.
        (human_floor, human_ceiling, human_round_to_even): Now have
        values 2, 0, 1 rather than -1, 1, 0.
        (human_group_digits, human_suppress_point_zero, human_autoscale,
        human_base_1024, human_SI, human_B): New constants.
        (human_readable_inexact, human_block_size): Remove.
        (human_readable): Size args are now uintmax_t, not int.
        (human_options): New decl.

        * exclude.c: (new_exclude, add_exclude): Remove casts that are
        unnecessary now that we assume C89 or better.  This change
        imported from coreutils.

        * mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.  This is the same patch as 2003-05-28, but it got lost
        in the 2003-05-30 sync from glibc.

        .h files should stand alone, but we shouldn't include <sys/types.h>
        if we can get away with just <stddef.h>.

        * __fpending.h, addext.c, backupfile.c, exclude.c, getline.c,
        malloc.c, putenv.c, realloc.c, strcasecmp.c: Include <stddef.h>
        rather than <sys/types.h>, as we merely need size_t.
        * dirname.h, memcoll.h, xalloc.h, xmemcoll.h: Include <stddef.h>,
        to get size_t.
        * hash.h, linebuffer.h, readtokens.h, stdio-safer.h, version-etc.h:
        Include <stdio.h>, to get FILE.
        * memcasecmp.c: Don't include <sys/types.h>, as we can assume
        memcasecmp.h has included <stddef.h> and all we need is size_t.
        * memcoll.c: Include "memcoll.h", which gets us size_t and checks
        our interface, instead of including <sys/types.h>

2003-06-02  Paul Eggert  <eggert@twinsun.com>

        [from coreutils]
        Fix some minor time-related bugs with POSIX time arguments.
        Some valid time stamps were being rejected (notably -1, and
        time stamps before 1900 on 64-bit hosts).  And some invalid
        time stamps were being accepted, e.g. September 31.

        * posixtm.h (posixtime): Return bool instead of time_t, so
        that we can return (time_t) -1 successfully.
        * posixtm.c: Likewise.
        [HAVE_STDBOOL_H]: Include <stdbool.h>.
        (bool, false, true) [!HAVE_STDBOOL_H]: New type.
        (t): Remove static var.
        (year, posix_time_parse): Now takes struct tm * arg to modify, instead
        of static var.  All uses changed.
        (year): Do not reject years before 1900; they can occur with
        64-bit time_t.
        (posix_time_parse): Do not check for out-of-range components;
        that is now the caller's responsibility, since our checks were
        only approximations.
        (posixtime): Use mktime to check for out-of-range components,
        since it knows them exactly.
        If mktime returns (time_t) -1, check whether an error actually occurred
        by invoking localtime on -1.
        (main) [TEST_POSIXTIME]: Check for input data errors, and report
        posixtime failures better.
        Improve the test data (in comments only).

2003-05-30    <karl@gnu.org>

        * mktime.c: update from libc.

2003-05-30  Bruno Haible  <bruno@clisp.org>

        * config.charset: Upgrade to gettext-0.12.1 and libiconv-1.9.1.

        rpmatch.c, userspec.c, xreadlink.c, xstrtol.c: Include <limits.h>
        without checking for HAVE_LIMITS_H.
        * backupfile.c, fsusage.c, hash.c, human.c, safe-read.c, userspec.c,
        xstrtol.c (CHAR_BIT) : Don't define, since <limits.h> is guaranteed
        to do that.
        * fatal.c: Include <stdarg.h> without checking for __STDC__.
        * exclude.c: Include <stdbool.h> unconditionally.
        * tempname.c: Include <stddef.h> unconditionally.
        * hash.c: Include <limits.h>, since we no longer define CHAR_BIT.
        * modechange.c, rpmatch.c (NULL): Don't define, since
        <stddef.h> does that.
        * quote.c: Dont include <stddef.h> or <sys/types.h>; not needed.
        * safe-read.c (INT_MAX): Don't define, since <limits.h> does that.
        * safe-read.c (TYPE_MINIMUM, TYPE_MAXIMUM): Remove; no longer needed.
        * xstrtol.c: Likewise.
        * safe-read.c: Remove TYPE_SIGNED; no longer needed.
        * savedir.c: Include <stddef.h> instead of defining NULL.

        * addext.c (addext): Use assignment rather than cast, to avoid
        warnings on some platforms.

        * mktime.c (__mktime_internal): Do not reject negative timestamps
        arbitrarily.

2003-05-10  Bruno Haible  <bruno@clisp.org>

        * linebreak.c (iconv_string_length): Don't return -1 just because the
        string is longer than 4 KB.

2003-05-12  Jim Meyering  <jim@meyering.net>

        * strftime.c (my_strftime): Let the `-' (no-pad) flag affect

2003-05-03  Bruno Haible  <bruno@clisp.org>

        Upgrade to Unicode-4.0.

        from 1 to 0. Change width of U+0CBF, U+0CC6, U+180E from 0 to 1.
        (uc_width): Change width of U+4DC0..U+4DFF from 2 to 1. Change width
        of U+2A6D7..U+2F7FF, U+2FA1E..U+2FFFD, U+30000..U+3FFFD from 1 to 2.
        Change width of U+E0100..U+E01EF from 1 to 0.

2003-04-25  Bruno Haible  <bruno@clisp.org>

        * copy-file.c: Include <stddef.h>, for size_t.

        of type size_t, not int.

        Merge changes from Coreutils.

        2003-03-22  Jim Meyering  <jim@meyering.net>

        2003-01-19  Ulrich Drepper  <drepper@redhat.com>

        From GNU libc.

        specifications for numeric values correctly.  Improve checks for
        overflow.

        2003-01-19  Jim Meyering  <jim@meyering.net>

        * strftime.c (widen) [COMPILE_WIDE]: Merge nearly-identical definitions.
        (nl_get_alt_digit) [! defined my_strftime]: Define.
        (my_strftime) [_NL_CURRENT]: Merge nearly-identical uses of
        _nl_get_alt_digit and _nl_get_walt_digit.

        * strftime.c (my_strftime): Merge in locale-related changes from libc.
        These changes have no effect outside of _LIBC.

        * mountlist.c (read_filesystem_list) [MOUNTED_VMOUNT]: Detect any
        error from mntctl.
        Use mntctl's return value to drive the entry-processing loop, since
        we can't rely on the value of the vmt_length member in the last
        entry.  On some systems doing so could result in exhausting
        virtual memory.  Based in part on a patch from Mike Jetzer.

        when compiling Bison 1.875's `bitset bset = obstack_alloc
        (bobstack, bytes);'.  Problem reported by Nelson H. F. Beebe.

        * getstr.h, getstr.c: Remove.

        (getline, getdelim): Adjust to renaming of getstr -> getdelim2.

        * linebuffer.c (readlinebuffer): Renamed from readline.

        * .cppi-disable: re-add strdup.c

2002-11-25    <karl@gnu.org>

2002-11-22  Paul Eggert  <eggert@twinsun.com>

        hint that one should use `if (! x) abort ();' rather than `assert
        (x);', and anyway it's one less thing to worry about configuring.
        (hash_lookup, hash_get_first, hash_get_next, hash_find_entry,
        hash_rehash, hash_insert): Use abort rather than assert.

        (UINTMAX_MAX) [!defined UINTMAX_MAX]: New macro.

2002-06-18  Paul Eggert  <eggert@twinsun.com>

        * file-type.h: Report an error if neither S_ISREG nor
        S_IFREG is defined, instead of using a test specific to glibc
        2.2.  This should be safe, since POSIX requires S_ISREG and
        Unix Version 7 had S_IFREG.  We don't need to check for
        <sys/types.h> since we don't use any symbols that it defines.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        * file-type.h (FILE_TYPE_H): Guard entire contents with #ifndef.
        For GNU libc 2.2 and newer, ensure that <sys/types.h> and <sys/stat.h>
        have been included before this file.

2002-06-13  Richard Dawe  <richdawe@bigfoot.com>

        * Makefile.am (lstat.c, stat.c, .sin.sed): Use t-$@, rather than $@-t,
        so that each temporary file name is unique and valid in the first
        8 characters, for operation under DOS.

2002-06-15  Jim Meyering  <meyering@lucent.com>

        Work even with DJGPP 2.03, which lacks support for symlinks.
        From Richard Dawe.
        * xstat.in (S_ISLNK): Define to 0 if neither S_ISLNK nor S_IFLNK
        is defined.
        * lchown.c (S_ISLNK): Likewise.

2002-06-14  Jim Meyering  <meyering@lucent.com>

        * file-type.h: Use the version from diffutils-2.8.2.
        * file-type.c: Likewise.

2002-05-27  Jim Meyering  <meyering@lucent.com>

        Fix a problem seen only on nonconforming systems whereby ls.c's
        use of localtime, and then of gettimeofday would cause trouble:
        the localtime call used to initialize rpl_gettimeofday's save
        mechanism would clobber ls's current local time information so
        that in any long listing the first file would always be listed
        with date 1970-01-01.  Analysis by Volker Borchert.

        * gettimeofday.c (localtime): Undefine.
        (rpl_localtime): New function.

2002-04-29  Paul Eggert  <eggert@twinsun.com>

        * hard-locale.c: Upgrade to version used in GNU Diffutils 2.8.1.

2002-04-28  Paul Eggert  <eggert@twinsun.com>

        * sig2str.h (SIGNUM_BOUND): Do not use WTERMSIG, to avoid
        depending on <sys/wait.h> and WTERMSIG.  Default to 64 instead
        of 127, since 64 is the largest conceivable number for ancient
        nonstandard hosts.
        * sig2str.c: Do not include <sys/wait.h>; no longer needed.

2002-04-28  Jim Meyering  <meyering@lucent.com>

        * sig2str.c (WTERMSIG): Remove definition (unused).

2002-04-28  Paul Eggert  <eggert@twinsun.com>

2002-04-16  Jim Meyering  <meyering@lucent.com>

        * readutmp.h (UT_TYPE): Remove definition (now in who.c).
        (HAVE_STRUCT_XTMP_UT_EXIT, HAVE_STRUCT_XTMP_UT_ID): Define.
        (HAVE_STRUCT_XTMP_UT_PID, HAVE_STRUCT_XTMP_UT_TYPE): Define.

2002-04-12  Jim Meyering  <meyering@lucent.com>

        * dirfd.h (dirfd): Elide prototype if dirfd is a macro.

2002-03-10  Jim Meyering  <meyering@lucent.com>

        * makepath.c (make_path): Remove a comma from a diagnostic.
        Suggestion from Santiago Vila.

2002-03-08  Jim Meyering  <meyering@lucent.com>

        * rename.c: Mention that this wrapper is needed also on
        mips-dec-ultrix4.4 systems.

2002-03-02  Jim Meyering  <meyering@lucent.com>

        * gettime.c (gettime): Test HAVE_CLOCK_GETTIME,
        not HAVE_CLOCK_SETTIME.

2002-02-27  Paul Eggert  <eggert@twinsun.com>

        * nanosleep.h: Rename to....
        * timespec.h: New name for nanosleep.h.  All uses changed.

        * gettime.c: New file.

        * acl.c, acl.h: New files.
        * Makefile.am (libfetish_a_SOURCES): Add acl.h, acl.c.

2002-02-24  Jim Meyering  <meyering@lucent.com>

        * strnlen.c (strnlen): Define-away/undef so that an inconsistent
        prototype in string.h (on at least AIX4.3.2.0 w/gcc-2.95.3) doesn't
        cause trouble.  Reported by Nelson Beebe.

2002-02-23  Paul Eggert  <eggert@twinsun.com>

        * path-concat.c (xpath_concat): Reorder code to pacify
        compilers that don't know that xalloc_die never returns.

2002-02-20  Jim Meyering  <meyering@lucent.com>

        * getdate.c: Regenerate using bison-1.33.

2002-02-15  Paul Eggert  <eggert@twinsun.com>

        (fwrite_success_callback): New declaration.
        * unicodeio.c (unicode_to_mb): New function, extracted from
        print_unicode_char. Call failure callback instead of error.
        (fwrite_success_callback): New function.
        (exit_failure_callback): New function.
        (fallback_failure_callback): New function.
        (print_unicode_char): Call unicode_to_mb.

2002-01-26  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (getdate$U.o): Depend on unlocked-io.h.

2002-01-22  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (Makefile): Don't depend on $(BUILT_SOURCES).
        Otherwise, some versions of automake would omit the rule that makes
        Makefile from Makefile.in.

2001-01-21  Paul Eggert  <eggert@twinsun.com>

        * xmemcoll.h, xmemcoll.c: New files.

        * quotearg.c (quotearg_buffer_restyled):
        Fix bug with quoting buffers containing NUL when backslashing escapes.
        This bug was exposed by the other changes in this patch.

        All callers changed.
        (quoting_options_from_style): New function.

        (quotearg_n_style_mem): New function.

        * quotearg.h (quotearg_n_style_mem): New function.

2002-01-16  Jim Meyering  <meyering@lucent.com>

        * getdate.y: Add three semicolons, each just before a closing brace.
        Bison (as of version 1.31) no longer papers over that mistake.

2002-02-14  Paul Eggert  <eggert@twinsun.com>

        * backupfile.c (ISDIGIT): Comment fix.
        * getdate.y (ISDIGIT): Likewise.
        * posixtm.c (ISDIGIT, year): Likewise.
        * strverscmp.c (ISDIGIT): Likewise.
        * userspec.c (ISDIGIT): Likewise.

        have nothing pending.

2001-12-18  Paul Eggert  <eggert@twinsun.com>

        See the big note in ../ChangeLog.
        * human.c (suffixes): Prefer K to k for 1024.
        (generate_suffix_backwards): New function.
        (human_readable_inexact): Use it.
        * xstrtol.c (__xstrtol): If there is no number but there
        is a valid suffix, assume 1.  "MB" now means decimal, "MiB" binary.
        Accept 'K' as well as 'k'.

2001-12-15  Jim Meyering  <meyering@lucent.com>

        * regex.h (__restrict_arr): Update from libc.

        * mountlist.h (ME_REMOTE): Recognize file systems of type smbfs
        as `remote' if the name starts with `//'.  Suggested by Michael Stone.
        (STREQ): Define.

2001-12-10  Jim Meyering  <meyering@lucent.com>

        * linebuffer.c: Remove explicit declarations of xmalloc and xrealloc,
        Instead, include "xalloc.h".
        (initbuffer): Don't cast xmalloc return value to char*.
        (readline): Reword comment.
        Don't cast xrealloc return value to char*
        Return NULL, not 0.

2001-12-09  Jim Meyering  <meyering@lucent.com>

        * modechange.c (mode_compile): Add cast to avoid pedantic warning about
        `signed and unsigned type in conditional expression'.
        * posixtm.c (posix_time_parse): Likewise.

        * xreadlink.c (xreadlink): Add cast to avoid a pedantic warning.

        * readtokens.c (readtoken): Declare an index to be of type unsigned
        to avoid a pedantic warning.

        * getstr.c: Don't include assert.h.
        (getstr): Remove warning-evoking assertions.
        Return -1 if offset parameter is out of bounds.
        Change the type of a local from int to size_t.

        * strftime.c (my_strftime_localtime_r): Include this function
        definition in the `#if ! HAVE_TM_GMTOFF' block.

        * xgethostname.c: Remove declarations of xmalloc and xrealloc.
        Include xalloc.h instead.

2001-12-02  Jim Meyering  <meyering@lucent.com>

        * tempname.c: Don't declare getenv, thus reverting the change of
        2001-11-18.  It's no longer necessary, now that stdlib.h is always
        included.

        * regex.c [!__BOUNDED_POINTERS__]: Define away __bounded,
        __unbounded, and __ptrvalue.  Reported by Uwe H. Steinfeld.

2001-11-30  Akim Demaille  <akim@epita.fr>

        * xstrdup.c: Include xalloc.h, so that xstrdup is declared
        before being defined.

2001-11-27  Paul Eggert  <eggert@twinsun.com>

        * quotearg.h (quotearg_n, quotearg_n_style):
        First arg is int, not unsigned.
        * quotearg.c (quotearg_n, quotearg_n_style): Likewise.
        (SIZE_MAX, UINT_MAX): New macros.
        (quotearg_n_options): Abort if N is negative.
        Avoid overflow check on hosts where size_t is 64 bits and int
        is 32 bits, as overflow is impossible there.
        Fix off-by-one typo that caused unnecessary reallocation.

2001-11-27  Jim Meyering  <meyering@lucent.com>

        * tempname.c: Merge with version from libc.
        * regex.c: Likewise.

        * tempname.c: Include stdlib.h unconditionally.  On some old systems
        for which STDC_HEADERS is 0, it was not included, resulting in a
        warning about an integer-to-pointer conversion problem with getenv.
        Reported by Volker Borchert.

2001-11-26  Jim Meyering  <meyering@lucent.com>

        * gtod.h: Remove file.
        * Makefile.am (libfetish_a_SOURCES): Remove gtod.h.
        * gettimeofday.c: Don't include gtod.h.
        (GTOD_init): Remove function.
        (rpl_gettimeofday): Do its job here instead, rather than aborting.
        Suggestion from Volker Borchert.

2001-11-23  Jim Meyering  <meyering@lucent.com>

        * hash.h (struct hash_table): Don't define here.  Merely declare it.
        * hash.c (struct hash_table): Define it here instead.

2001-11-22  Jim Meyering  <meyering@lucent.com>

        * hash.h: Bracket contents of file with #ifndef HASH_H_ ... #endif.

2001-11-18  Paul Eggert  <eggert@twinsun.com>

        * tempname.c (TMP_MAX): Remove; no longer needed.
        (TEMPORARIES): New macro.
        (__gen_tempname): Use TEMPORARIES rather than TMP_MAX.  This
        removes an artificial limitation (e.g. HP-UX 10.20, where
        TMP_MAX is 17576).

2001-11-18  Jim Meyering  <meyering@lucent.com>

        * tempname.c [!HAVE_DECL_GETENV]: Declare getenv to avoid warning
        on SunOS 4.

        * Makefile.am (Makefile): Depend on $(BUILT_SOURCES), so those
        files will be created before anything else.

2001-11-17  Jim Meyering  <meyering@lucent.com>

        * modechange.c (mode_adjust): Fix error introduced on 1999-04-26
        that made e.g., `chmod a=,o=w,g=o F' cause F to be group readable
        rather than group writable.  Patch by Juan F. Codagnone.

        * readtokens.c: Remove explicit declarations of xmalloc and xrealloc,
        Instead, include "xalloc.h".

        * mountlist.c: Include unlocked-io.h after all system headers.
        Remove explicit declarations of xmalloc, xrealloc,
        and xstrdup.  Instead, include "xalloc.h".

        * argmatch.c, closeout.c, error.c, exclude.c: Include unlocked-io.h.
        * fatal.c, getdate.y, getpass.c, getstr.c, getusershell.c: Likewise.
        * mountlist.c, posixtm.c, readtokens.c, readutmp.c: Likewise.

        * regex.c, sha.c, version-etc.c, yesno.c: Likewise.
        Reported by Padraig Brady.

        * mkstemp.c: #undef mkstemp.
        Include config.h.
        (rpl_mkstemp): Rename from mkstemp.
        Protoize.

2001-11-16  Jim Meyering  <meyering@lucent.com>

        * physmem.c [HAVE_SYS_PSTAT_H]: Include <sys/pstat.h>.
        (physmem_total) [HAVE_PSTAT_GETSTATIC]: If sysconf couldn't be used to
        determine the amount of total physical memory, use pstat_getstatic.
        HPUX-11 doesn't define _SC_PHYS_PAGES.
        (physmem_available) [HAVE_PSTAT_GETSTATIC && HAVE_PSTAT_GETDYNAMIC]:
        If sysconf couldn't be used to determine the amount of available
        physical memory, use both pstat_getstatic and pstat_getdynamic.
        Based on a patch from Bob Proulx.

2001-11-05  Jim Meyering  <meyering@lucent.com>

        * xstat.in (slash_aware_lstat): Correct a misleading comment.

2001-11-03  Jim Meyering  <meyering@lucent.com>

        * argmatch.h (ARGMATCH_TO_ARGUMENT): Remove casts of first two args
        in argmatch_to_argument call.

        * dirfd.c (dirfd): Reflect the fact that DIR_TO_FD now takes an
        argument.

        * hash.c (hash_clear): Fix a bug that could lead to an infloop or
        e.g., a fault due to an attempt to free a NULL pointer.

2001-11-01  Jim Meyering  <meyering@lucent.com>

        * dirfd.c, dirfd.h: New files.

        to avoid a warning if -Wall.

2001-10-21  Paul Eggert  <eggert@twinsun.com>

        * regex.c (uintptr_t): Remove macro and decl; it's config.h's job.

2001-10-21  Jim Meyering  <meyering@lucent.com>

        * obstack.c (_): Honor the setting of ENABLE_NLS.  Otherwise,
        this code would end up calling gettext even in packages built
        with --disable-nls.
        * getopt.c (_): Likewise.
        * regex.c (_): Likewise.

2001-10-20  Paul Eggert  <eggert@twinsun.com>

        * error.c (strerror_r): Do not declare unless !_LIBC.
        Do not check for HAVE_DECL_STRERROR_R missing unless STRERROR_R_CHAR_P.
        Use strerror_r that is only a macro, even if it is not a function.
        (strerror): Check for HAVE_DECL_STRERROR before declaring.
        (private_strerror): Use prototypes, not old-style function definition.
        (print_errno_message): New function.
        Support the POSIX 'int'-flavored strerror_r, as well as the traditional
        char*-flavored one.
        (error_tail, error, error_at_line): Use it.

2001-10-11  Jim Meyering  <meyering@lucent.com>

        * argmatch.c (argmatch_invalid): Use quotearg_n_style (0, ...
        and quote_n (1, ... to avoid clobbering a buffer.

2001-10-05  Jim Meyering  <meyering@lucent.com>

        * Makefile.am: (libfetish_a_SOURCES): Add hash-pjw.c and hash-pjw.h.
        * hash-pjw.c: New file (factored out of fileutils' remove.c).
        * hash-pjw.h: New file.

2001-09-30  Jim Meyering  <meyering@lucent.com>

        * mountlist.c [MOUNTED_GETFSSTAT]:
        Include <sys/ucred.h>, for Apple Darwin.
        Include sys/mount.h and sys/fs_types.h only if available.
        (FS_TYPE): Define.
        (read_filesystem_list): Use FS_TYPE.

2001-09-29  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (excluded_filename): 0 -> false, since it's
        a boolean context.

2001-09-28  Paul Eggert  <eggert@twinsun.com>

        Fix bug reported by Petter Reinholdtsen for HP-UX 10.20, which
        #defines strtoimax.  Also treat the other strto* functions
        like strtoimax.

        * xstrtol.c (strtol): Do not declare if HAVE_DECL_STRTOL.
        (strtoul): Do not declare if HAVE_DECL_STRTOUL.
        (strtoimax, strtoumax): Do not declare if already defined as a macro.

2001-09-26  Jim Meyering  <meyering@lucent.com>

        Most macros in unlocked-io.h had the wrong number of arguments.
        * gen-uio: New script.
        (USE_UNLOCKED_IO): Define to 1 if not already defined.
        * unlocked-io.hin: Remove file.
        * Makefile.am (unlocked-io.h): Rewrite to use a separate script,
        rather than trying to embed it here.
        (EXTRA_DIST): Add gen-uio.  Remove unlocked-io.hin
        Reported by Padraig Brady.

2001-09-25  Volker Borchert  <bt@teknon.de>

        * gettimeofday.c (rpl_gettimeofday): Declare local variable `result'.

2001-09-23  Jim Meyering  <meyering@lucent.com>

        * mountlist.c: Remove useless parentheses in #if directives.
        (MOUNTED) [!defined MOUNTED]: Define to _PATH_MOUNTED, for when
        the deprecated MOUNTED symbol is no longer defined in mntent.h.

2001-09-22  Jim Meyering  <meyering@lucent.com>

        * localcharset.c: Update from latest gettext.
        * config.charset: Likewise.

2001-09-20  Jim Meyering  <meyering@lucent.com>

        * xstrtol.c (strtoimax): Guard declaration with
        `#if !HAVE_DECL_STRTOIMAX', rather than just `#ifndef strtoimax'.
        The latter fails because some systems (at least rs6000-ibm-aix4.3.3.0)
        have their own, conflicting declaration of strtoimax in sys/inttypes.h.
        (strtoumax): Likewise, for completeness (it wasn't necessary).

2001-09-06  Paul Eggert  <eggert@twinsun.com>

        * strtoimax.c (HAVE_LONG_LONG):
        Redefine to HAVE_UNSIGNED_LONG_LONG if unsigned.
        (strtoimax): Use sizeof (long), not sizeof strtol (ptr, endptr, base),
        to work around bug in IBM C compiler.

2001-09-16  Jim Meyering  <meyering@lucent.com>

        * mkdir.c: New file.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Revert some of the previous change; intead,
        fix the HAVE_GETCWD_NULL code to behave more like the
        !HAVE_GETCWD_NULL code used to.

        Include "xalloc.h".
        (xgetcwd): Do not return NULL when memory is exhausted; instead,
        invoke xalloc_die.

2001-09-04  Paul Eggert  <eggert@twinsun.com>

        * xreadlink.c (xreadlink): Omit size_t* arg.  All uses changed.
        Use ssize_t, not int, to store result of readlink.
        Check for ssize_t overflow as well as size_t overflow,
        as POSIX says the result of readlink is implementation-defined
        when ssize_t overflows.
        Remove unnecessary cast to char*.
        Use free+malloc instead of realloc, as the storage doesn't need
        to be preserved and it's clearer and can be more efficient that way.
        (SIZE_MAX, SSIZE_MAX): New macros, if <limits.h> doesn't declare.
        * xreadlink.h (xreadlink): Update prototype.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (fnmatch_no_wildcards): Fix confusion between
        usage of FNM_CASEFOLD and FNM_LEADING_DIR.  The bug was
        spotted by Jim Meyering.

2001-09-03  Jim Meyering  <meyering@lucent.com>

        * xreadlink.c (xreadlink): Preserve errno around `free' during failure.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Fix the !HAVE_GETCWD_NULL code to behave more
        like the HAVE_GETCWD_NULL code.
        Include pathmax.h if not HAVE_GETCWD.
        Do not include xalloc.h.
        (INITIAL_BUFFER_SIZE): New symbol.
        Do not use xmalloc / xrealloc, since the caller is responsible for
        handling errors.  Preserve errno around `free' during failure.
        Do not overrun buffer when using getwd.

2001-09-03  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c (xgetcwd): Use HAVE_GETCWD_NULL, not (defined
        __GLIBC__ && __GLIBC__ >= 2), to decide whether to use getcwd (NULL, 0).

2001-09-02  Jim Meyering  <meyering@lucent.com>

        * error.c: Update from GNU libc.

2001-09-01  Jim Meyering  <meyering@lucent.com>

        * xreadlink.c: New file.
        * xreadlink.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add xreadlink.c and xreadlink.h.

        * regex.c (uintptr_t) [!_LIBC]: Define to private_uintptr_t, so it
        doesn't conflict with sparc Solaris 7's definition in
        /usr/include/sys/int_types.h.

        * exclude.c: Use `""', not `<>' to #include non-system header files.
        (fnmatch_no_wildcards): Rewrite not to use function names, strcasecmp
        and strncasecmp as r-values.  Unixware didn't have declarations.

2001-08-31  Jim Meyering  <meyering@lucent.com>

        * xgetcwd.c (xgetcwd): Reorganize to avoid some duplication.
        Use an initial, malloc'd, buffer of length 128 rather than
        a statically allocated one of length 1024.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * xgetcwd.c: Don't include pathmax.h.
        Include stdlib.h and unistd.h if available.
        Include xalloc.h.
        (xmalloc, xstrdup, free): Remove decls.
        (xgetcwd): Don't assume sizes fit in unsigned.
        Check for overflow when computing sizes.
        Simplify reallocation code.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (libfetish_a_SOURCES): Remove strtoxmax.c.

        * strtoimax.c: Renamed from strtoxmax.c, removing the
        old strtoimax.c.

        Also, make the following further changes to make this file's
        configuration more similar to that of strtol.c:
        (UNSIGNED): Renamed from STRTOUXMAX_UNSIGNED.  All uses changed.
        (strtoumax, uintmax_t, strtoull, strtol): Remove.
        (intmax_t, strtoimax, strtol, strtoll): New macros, if UNSIGNED.
        (strtoimax): Renamed from strtoumax.  All uses of unsigned values
        changed to signed values.

        And make the following changes as well:
        Fix copyright notice, as 1999 was missing.
        (verify): New macro.
        (strtoimax): Check sizes at compile-time, not run-time.
        Prefer strtol to strtoll if both work.
        (main): Remove; it was not that useful and was a pain to maintain.

        * strtoumax.c: Include strtoimax.c, not strtouxmax.c.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * savedir.c (savedir): Remove size parameter, as POSIX says that
        a directory's st_size can have an arbitrary value, so the old
        usage could waste an arbitrary amount of memory.  All uses
        changed.
        * savedir.h: Update prototype.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * xstrtol.c (strtoimax): New decl.

2001-08-28  Paul Eggert  <eggert@twinsun.com>

        * xstrtol.h: Add copyright notice.
        (_DECLARE_XSTRTOL): Improve quality of diagnostic for
        LONGINT_INVALID_SUFFIX_CHAR.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c: BSD/OS 4.1 wchar.h requires FILE and struct
        tm to be declared.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * hash.c: Remove '2001' from copyright notice.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * full-write.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add full-write.h.
        * full-write.c: Correct credits, as cccp.c no longer
        exists and anyway it was so heavily changed from the old cccp
        code as to be unrecognizable.  Include full-write.h.
        (full_write) Return size_t, with short writes meaning failure.
        All callers changed.  This fixes a bug with large buffers
        on 64-bit hosts.
        * utime.c: Include full-write.h.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        Merge 'exclude' changes from tar 1.13.22.
        This fixes one or two unlikely storage allocation overflow bugs,
        but doesn't change user-visible behavior otherwise.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * exclude.c (bool): Declare, perhaps by including stdbool.h.
        (<sys/types.h>): Include only if HAVE_SYS_TYPES_H.
        (<stdlib.h>, <string.h>, <strings.h>, <inttypes.h>, <stdint.h>):
        Include if available.
        (<xalloc.h>): Include
        (SIZE_MAX): Define if <stdint.h> or <inttypes.h> doesn't.
        (verify): New macro.  Use it to verify that EXCLUDE macros do not
        collide with FNM macros.
        (struct patopts): New struct.
        (struct exclude): Use it, as exclude patterns now come with options.
        (new_exclude): Support above changes.
        (new_exclude, add_exclude_file):
        Initial size must now be a power of two to simplify overflow checking.
        (free_exclude, fnmatch_no_wildcards): New function.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.
        (excluded_filename, add_exclude):
        Add support for the fancy new exclusion options.
        (add_exclude, add_exclude_file): Now takes int options arg.
        Check for arithmetic overflow when computing sizes.
        (add_exclude_file): xrealloc might modify errno, so don't
        realloc until after errno might be used.

        * exclude.h (EXCLUDE_ANCHORED, EXCLUDE_INCLUDE,EXCLUDE_WILDCARDS):
        New macros.
        (free_exclude): New decl.
        (add_exclude, add_exclude_file): Now takes int options arg.
        (excluded_filename): No longer requires options arg, as the options
        are determined by add_exclude.  Now returns bool, not int.

2001-08-30  Paul Eggert  <eggert@twinsun.com>

        * alloca.c (alloca): Arg is of type size_t, not unsigned.

2001-08-27  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (libfetish_a_SOURCES): Add strtoxmax.c

        * version-etc.c (N_): Remove definition.
        Revert most of last change.
        Instead, simply don't mark the `Copyright...' string for translation.
        Based on advice from Paul Eggert.

        * strtoxmax.c: Tweak comment.

2001-08-26  Jim Meyering  <meyering@lucent.com>

        * version-etc.c (version_etc_copyright_fmt): Replace literal year
        of copyright with `%s' so translators don't get an untranslated
        message in 2002.
        (COPYRIGHT_YEAR): Define.
        (version_etc): Use fprintf rather than fputs.
        Suggestion from Ulrich Drepper.

        * Makefile.am (libfetish_a_SOURCES): Add xstrtoimax.c.

        * strtoll.c: New file, from GNU libc.
        * xstrtoimax.c: New file.

        * xstrtol.h: Add xstrtoimax.
        * strtoumax.c: New file.  Simply include "strtoumax.c".
        * strtoimax.c: New file.  Likewise, but first define STRTOUXMAX_SIGNED.

        * strtoumax.c: Factor to work both for unsigned and signed types, ...
        * strtoxmax.c: ... then renamed to this.

2001-08-13  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (unlocked-io.h): Do not append "_unlocked" twice.
        Port to Solaris 8, where 'sed' requires a space after the 'r'
        command, and where sh dislikes "$/".  Clean up the spacing a bit.
        Redirect output to $tmp just once.

2001-08-12  Paul Eggert  <eggert@sic.twinsun.com>

        * addext.c (<errno.h>): Include.
        (errno): Declare if not defined.
        (addext): Work correctly when pathconf returns -1 and leaves
        errno alone because there is no limit.  Also, work even if
        pathconf returns a value greater than SIZE_MAX.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        * xgetcwd.c (xgetcwd) [defined __GLIBC__ && __GLIBC__ >= 2]:
        Simply `return getcwd (NULL, 0);'.
        [! (defined __GLIBC__ && __GLIBC__ >= 2)]:
        Use 1300 as initial value for length, not PATH_MAX.

        * pathmax.h: Clean up cpp syntax.

2001-08-12  Jim Meyering  <meyering@lucent.com>

        * gettimeofday.c: New file.

        to get in sync with glibc.

2001-08-03  Paul Eggert  <eggert@twinsun.com>

        The following changes are from gettext 0.10.39 as maintained by
        Bruno Haible.

        * mbswidth.h (MBSW_REJECT_UNPRINTABLE, MBSW_REJECT_INVALID):
        Renamed from MBSW_ACCEPT_UNPRINTABLE and MBSW_ACCEPT_INVALID
        with inverted sense.  All uses changed.

        * mbswidth.c: Don't include <limits.h>.
        Include <stdlib.h> and <string.h> unconditionally.
        (iswcntrl, mbsinit, ISCNTRL): New macros.
        (mbsnwidth): Use K&R style function declarations.
        Don't bother checking for MB_LEN_MAX == 1, since the compiler
        can optimize it when MB_CUR_MAX == 1.
        The width of control characters is zero, not 1.

2001-07-15  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (EXTRA_DIST): Add unlocked-io.hin.
        (BUILT_SOURCES): Add unlocked-io.h.

        quote function.  Reported by Göran Uddeborg.

2001-05-20  Alexandre Duret-Lutz  <duret_g@epita.fr>

        * dirname.c (dir_name): Compute append_dot using path, not newpath
        which is not yet declared.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        Add strftime.c, since we now compile it on all hosts.

        * strftime.c (my_strftime):
        Define to nstrftime if emacs, but only if my_strftime is not defined.
        (extra_args, extra_args_spec, extra_args_spec_iso): Rename from

        (ns): New macro.
        (my_strftime function): Add %N format.
        (emacs_strftimeu): Renamed from emacs_strftime,
        with extra ut argument.

2001-05-11  Paul Eggert  <eggert@twinsun.com>

        dirname code cleanup.  base_name now behaves more compatibly
        with POSIX basename when given file names that have trailing
        slashes, and similarly for dir_name.  Add new primitives
        base_len and dir_len.  Put the directory-name-related decls
        into dirname.h.

        * addext.c (ISSLASH, base_name): Remove; now in dirname.h.
        * backupfile.c (base_name): Likewise.
        * basename.c (FILESYSTEM_PREFIX_LEN, PARAMS, ISSLASH): Likewise.
        * dirname.c (FILESYSTEM_PREFIX_LEN, ISSLASH): Likewise.
        * makepath.c (strip_trailing_slashes): Likewise.
        * path-concat.c (DIRECTORY_SEPARATOR, FILESYSTEM_PREFIX_LEN, ISSLASH):
        Likewise.
        * rename.c (strip_trailing_slashes): Likewise.
        * same.c (base_name): Likewise.
        * stripslash.c (ISSLASH): Likewise.

        * addext.c: Include <dirname.h> after size_t is defined.
        * backupfile.c: Likewise.

        * addext.c (addext): Use base_len to trim redundant
        trailing slashes instead of doing it ourselves.
        But do not trim the last slash if it is not redundant.

        * backupfile.c (find_backup_file_name,
        max_backup_version): Use base_len instead of rolling it ourselves.
        Handle the case of "" and (on DOS) "C:" correctly.

        * basename.c: Do not include <stdio.h>, <assert.h>; no longer needed.
        Include <string.h>, <dirname.h>.
        (base_name): Allow file names ending in slashes, other than names
        that are all slashes.  In this case, return the basename followed
        by the slashes.  This is more general, and can be used in places
        where the original base_name purposely had an assertion failure.
        (base_len): New function.

        * dirname.c: Include <string.h> instead of <stdlib.h>.
        Do not include <assert.h>; no longer needed.
        Include xalloc.h.
        (memrchr): Remove decl.
        (dir_name_r): Remove.
        (dir_len): Renamed from dirlen.  All callers changed.
        Rewrite in terms of base_name, for simplicity and consistency.
        (dir_name): Never return NULL.  All callers changed.
        Do not include <stdlib.h> in test program; no longer needed.
        return 0; is fine for test program.

        * dirname.h (DIRECTORY_SEPARATOR, ISSLASH, FILESYSTEM_PREFIX_LEN):
        New macros.
        (base_name, base_len, dir_len, strip_trailing_slashes): New decls.

        * path-concat.c (path_concat): Use base_len to compute
        base length, not strlen; this means we cannot rely on memcpy
        to null-terminate.

        * same.c (STREQ): Remove.
        (same_name): Handle the case where the basename ends in trailing '/'.

        * stripslash.c (strip_trailing_slashes): Return nonzero if
        a slash was stripped.  Do not strip the last slash after a
        file system prefix.

2001-04-08  Jim Meyering  <meyering@lucent.com>

        * getdate.y (get_date): Set tm_isdst to -1 to ensure that it is
        recomputed; that's necessary when the offset spans a DST transition.
        Patch by David J. MacKenzie.  Reported by Hon-Yin Kok.

2001-04-02  Jim Meyering  <meyering@lucent.com>

        * regex.h, regex.c: Update from GNU libc.

        * tempname.c (uint64_t): Define to uintmax_t if
        not defined, and if UINT64_MAX is not defined.
        Required at least for Vax Ultrix4.3, which doesn't define uint64_t.
        Reported by John David Anglin.

2001-03-10  Bruno Haible  <haible@clisp.cons.org>

        * localcharset.c (locale_charset): Allow wildcard syntax. Also resolve
        alias if codeset is empty.
        * config.charset (BeOS): Use wildcard syntax.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * path-concat.c (path_concat) [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]:

        From Bruno Haible.

2001-03-06  Bruno Haible  <haible@clisp.cons.org>

        * localcharset.c (locale_charset): Don't use setlocale(LC_CTYPE,NULL).
        Don't return NULL.

        The mkstemp replacement is taken from glibc 2.2.2, with some
        portability fixes for use outside glibc, as follows:

        * tempname.c (struct_stat64): New macro.
        (direxists, __gen_tempname): Use it.
        This avoids a portability problem with Solaris 8.

        Define these macros if <stdio.h> doesn't.
        (S_ISDIR, S_IRUSR, S_IWUSR, S_IXUSR):
        Define these macros if <sys/stat.h>
        doesn't.  Ignore <sys/stat.h> S_ISDIR if STAT_MACROS_BROKEN.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * mbswidth.c, quotearg.c (mbrtowc, mbsinit):
        Remove workaround macros for hosts that have mbrtowc but not

        * regex.c: Update from libc.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

        may have defined it.  Needed for Encore Umax-3.0.9.16b systems.
        Reported by Mark Hounschell via Paul Eggert.

2001-01-30  Bruno Haible  <haible@clisp.cons.org>

        Reported by Axel Kittenberger.

2001-01-15  Bruno Haible  <haible@clisp.cons.org>

        local `inptr' to avoid warning with some system declarations of iconv.

2000-12-29  Paul Eggert  <eggert@twinsun.com>

        * modechange.c: Do not assume that mode_t uses the
        traditional octal encoding.  E.g. "chmod 1 FOO" should set
        the other-execute bit of FOO even if S_IXOTH != 1.

        (SUID, SGID, SVTX, RUSR, WUSR, XUSR, RGRP, WGRP, XGRP, ROTH,
        WOTH, XOTH, ALLM): New macros.
        (S_ISUID, S_ISGID, S_ISVTX, S_IRUSR, S_IWUSR, S_IXUSR,
         S_IRGRP, S_IWGRP, S_IXGRP, S_IROTH, S_IWOTH, S_IXOTH):
        Use them.
        (S_ISGID): Fix typo; it was defaulting to the same value as S_ISUID.
        (S_IRWXU, S_IRWXG, S_IRWXO): Specify defaults in terms of the above.
        (mode_compile):
        No need to use uintmax_t; unsigned long is long enough.
        Don't bother to get suffix since we don't use it.

2000-12-24  Jim Meyering  <meyering@lucent.com>

        * hash.c (is_prime): Return explicit boolean values.
        (hash_get_first): Return NULL to appease Irix5.6's 89.
        Reported by Nelson Beebe.

2000-10-31  Bruno Haible  <haible@clisp.cons.org>

        Based mostly on a patch from Prashant TR.

2000-12-16  Jim Meyering  <meyering@lucent.com>

        This bug had a serious impact on chown: `chown N:M FILE' (for integer
        N and M) would have treated it like `chown N:N FILE'.

        * userspec.c (parse_user_spec): Fix typo: s/u/g/.

2000-10-31  Bruno Haible  <haible@clisp.cons.org>

        * config.charset: Add ISO-8859-3, BIG5HKSCS, GB18030, JOHAB, VISCII,
        CP874, CP949, CP950, CP1250, CP1253, CP1254, CP1255, CP1256, CP1257
        to the list of canonical encodings. Rename EUC-CN to GB2312.

2000-12-08  Andreas Schwab  <schwab@suse.de>

        * mbswidth.c (mbsnwidth): Don't loop endlessly when called with an
        invalid mulitbyte sequence and with the MBSW_ACCEPT_INVALID flag set.

2000-12-07  Jim Meyering  <meyering@lucent.com>

        * stripslash.c (ISSLASH): Define.
        (strip_trailing_slashes): Use ISSLASH rather than comparing against `/'.
        From Prashant TR.

        * dirname.c (FILESYSTEM_PREFIX_LEN): Define.
        (dir_name_r): Declare this function as static.
        [BACKSLASH_IS_PATH_SEPARATOR]: Fix a bug that'd
        manifest itself on a name containing a mix of slashes and
        backslashes.
        Make this function work with names starting with a DOS-style
        drive letter and colon prefix.
        (dir_name): Append `.' if necessary.
        Based mostly on patches from Prashant TR and Eli Zaretskii.

        * dirname.h (dir_name_r): Remove prototype.

2000-12-05  Jim Meyering  <meyering@lucent.com>

        Also include memory.h, stdlib.h, unistd.h if appropriate.
        Reported by Andreas Jaeger (conflicting declaration of malloc).

2000-12-02  Jim Meyering  <meyering@lucent.com>

        * closeout.h: Make idempotent, to avoid some obscure warnings.

2000-12-01  Paul Eggert  <eggert@twinsun.com>

2000-11-29  Paul Eggert  <eggert@twinsun.com>

        * dirname.c (dir_name_r): Fix typo: int -> size_t.

2000-11-26  Jim Meyering  <meyering@lucent.com>

        * memcoll.c: Include sys/types.h.  From Werner Almesberger.

2000-11-22  Paul Eggert  <eggert@twinsun.com>

        * strftime.c (my_strftime): Do not invoke mbrlen with a
        size of (size_t) -1; it's not portable.

2000-11-17  Akim Demaille  <akim@epita.fr>

        * obstack.h: Formatting changes.
        (obstack_grow, obstack_grow0): Don't cast WHERE at all: that would
        prevent type checking.
        (obstack_ptr_grow, obstack_ptr_grow_fast): When assigning, don't
        cast the value to (void *): assigning a `foo *' to a `void *'
        variable is valid.
        (obstack_int_grow, obstack_int_grow_fast): Don't cast AINT to int.

2000-11-17  Jim Meyering  <meyering@lucent.com>

        * getusershell.c (setusershell): Use rewind rather than
        fseek/fseeko, to avoid configuration hassles with fseeko.
        Don't bother opening SHELLS_FILE if shellstream is NULL;
        it's not necessary.

2000-11-05  Jim Meyering  <meyering@lucent.com>

        * makepath.h (make_dir): Declare.
        * makepath.c (make_dir): Remove `static' attribute.

        last one in a bucket, advance to the next bucket.

2000-11-02  Vesselin Atanasov  <vesselin@bgnet.bg>

        * fnmatch.c: Do not comment out all the code if we are using
        the GNU C library, because in some cases we are replacing buggy
        code in the GNU C library itself.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * error.h, getline.h, modechange.h:
        Remove "2000" from Copyright line, as the file hasn't been
        changed this year other than in the copyright notice.

        * xalloc.h: Add "2000" to Copyright line, as this file
        was changed this year.

2000-10-30  Paul Eggert  <eggert@twinsun.com>

        * fnmatch.c (FOLD): Do not assume that characters are unsigned.
        (fnmatch): Fix some FNM_FILE_NAME and FNM_LEADING_DIR bugs,
        e.g. fnmatch("d*/*1", "d/s/1", FNM_FILE_NAME) incorrectly yielded zero.

2000-10-29  Greg Louis  <glouis@dynamicro.on.ca>

        * regex.h (__restrict_arr): Move definition out of #ifndef block.
        Required because egcs-2.91.66 (aka 1.1.2) defines __restrict, but
        doesn't define __restrict_arr.

2000-10-29  Jim Meyering  <meyering@lucent.com>

        * memcmp.c: Likewise.

        * getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.

        Patch by Ulrich Drepper.

2000-10-26  Jim Meyering  <meyering@lucent.com>

        * strftime.c: Update from libc.

2000-10-23  Jim Meyering  <meyering@lucent.com>

        * hard-locale.c (hard_locale): Revert last change -- it was simply
        wrong.  That set_locale call must not have any side effects.
        From Paul Eggert.

2000-10-22  Jim Meyering  <meyering@lucent.com>

        * md5.c (md5_process_block) [OP]: Use `rol', not CYCLIC.

        (dir_name): Remove the restriction that there be no
        trailing slashes.  Now, this code skips past them, effectively
        ignoring them.
        [TEST_DIRNAME] (main): New unit tests.

        * memrchr.c: New file from GNU libc.
        Undef __memrchr, too.
        [!weak_alias]: Define __memrchr to memrchr.
        Guard weak_alias use with `#ifdef weak_alias'.

2000-10-17  Jim Meyering  <meyering@lucent.com>

        * mbswidth.c: Likewise
        * regex.c: Likewise.

        (xrealloc): Comment fix.

        * userspec.c (parse_user_spec):
        Don't translate a message until just before returning,
        to avoid unnecessary translation.

        From a suggestion by Jim Meyering.

        * dirname.c (dir_name) [MSDOS]: Declare `lim' to be const.
        (dir_name): Assert that there are no trailing slashes.

2000-07-18  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h (mbswidth): Add a flags argument.
        (mbswidth): New declaration.
        (MBSW_ACCEPT_INVALID, MBSW_ACCEPT_UNPRINTABLE): New macros.
        * mbswidth.c (mbswidth): Add a flags argument.
        (mbsnwidth): New function.

2000-07-24  Jim Meyering  <meyering@lucent.com>

        * mbswidth.c: Remove useless #else.  From Bruno Haible.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * mbswidth.c (_XOPEN_SOURCE):
        Don't define; this causes problems on Solaris 7.
        (wcwidth) [!HAVE_DECL_WCWIDTH]: Declare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c:
        Include <wchar.h> even if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX),
        so that mbstate_t is always defined.

        Do not inspect MB_LEN_MAX, since it's incorrectly defined to
        be 1 in at least one GCC installation, and this configuration
        error is likely to be common.  Ignoring MB_LEN_MAX hurts
        performance on hosts that have mbrtowc but have only unibyte
        locales, but I assume these hosts are rare.

2000-07-23  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c: Streamline by invoking multibyte code only if needed.
        <wchar.h>: Include only if HAVE_MBRTOWC && 1 < MB_LEN_MAX.
        (MB_CUR_MAX): Redefine to 1 if ! (HAVE_MBRTOWC && 1 < MB_LEN_MAX).
        (quotearg_buffer_restyled): If a unibyte locale, don't bother to
        invoke multibyte primitives.

2000-07-23  Jim Meyering  <meyering@lucent.com>

        * basename.c (base_name): Add an assertion.

2000-07-15  Bruno Haible  <clisp.cons.org>

        * quotearg.c: When the system forces us to redefine mbstate_t,
        shadow its mbsinit function.

2000-07-16  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h: New file.
        * mbswidth.c: New file.
        * Makefile.am (libfetish_a_SOURCES): Add mbswidth.c.
        (noinst_HEADERS): Add mbswidth.h.

2000-07-17  Bruno Haible  <haible@clisp.cons.org>

        * config.charset: Add support for FreeBSD. Improve support for HP-UX
        and IRIX 6.

        * makepath.c: Include quote.h.
        (make_path): Convert "`%s'" in format strings to "%s", and wrap each
        corresponding argument in a `quote (...)' call.
        Give better diagnostics.

        * Makefile.am (libfetish_a_SOURCES): Add quote.c.
        (noinst_HEADERS): Add quote.h.

        * quote.c (quote, quote_n): New file.  Two functions taken verbatim
        from tar's src/misc.c.
        * quote.h: New file.  Prototypes for same.

2000-07-10  Paul Eggert  <eggert@twinsun.com>

        From a suggestion by Bruno Haible.
        * quotearg.c (mbrtowc): Do not use HAVE_WCHAR_H in the definition.
        Use defined mbstate_t, not HAVE_MBSTATE_T_OBJECT,
        to decide whether to define the BeOS workaround macro;
        this adjusts to the change to AC_MBSTATE_T.

2000-07-13  Paul Eggert  <eggert@twinsun.com>

        * quotearg.h (enum quoting style): New enum clocale_quoting_style.

        * quotearg.c (quoting_style_args, quoting_style_vals,
        quotearg_buffer_restyled): Add support for
        clocale_quoting_style.  Undo previous change to
        locale_quoting_style behavior, and undo the "{LEFT QUOTATION MARK}"
        and "{RIGHT QUOTATION MARK}" msgids.

2000-07-05  Paul Eggert  <eggert@twinsun.com>

        The old behavior of quoting `like this' doesn't look good with
        newer, ISO-style fonts.  See:
        http://www.cl.cam.ac.uk/~mgk25/ucs/quotes.html

        Instead, quote "like this" by default.  Let the translator
        tailor the locale-specific quoting behavior by providing
        translations for {LEFT QUOTATION MARK} and {RIGHT QUOTATION MARK}.

        * quotearg.c (N_): New macro.
        (gettext_default): New function.
        (quotearg_buffer_restyled): Use
        gettext_default ("{LEFT QUOTATION MARK}", "\"") for left quote, and
        gettext_default ("{RIGHT QUOTATION MARK}", "\"") for right quote.

2000-07-09  Jim Meyering  <meyering@lucent.com>

        * Most files: Update copyright dates to include 2000.

2000-07-08  Jim Meyering  <meyering@lucent.com>

        * xgethostname.c (ENAMETOOLONG): Define to an unlikely value
        if not defined.
        (xgethostname): Remove now-unnecessary #ifdef.
        Move declaration of `err' into loop where it's used.

2000-07-05  Bruno Haible  <haible@clisp.cons.org>

        * xgethostname.c (xgethostname): Protect against the SunOS 5.5 bug
        by allocating a larger buffer. Test the gethostname return value for
        being >= 0, not == 0, for BeOS.  Don't exhaust memory if gethostname
        returns an error and ENAMETOOLONG isn't defined.

2000-07-05  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        dimension.

        Reported by Bruno Haible.

2000-07-04  Jim Meyering  <meyering@lucent.com>

        * quotearg.c: Make inclusion of <wchar.h> independent of whether
        HAVE_MBRTOWC is set.  Required at least for irix-5.6, which
        lacks mbrtowc.

2000-07-03  Paul Eggert  <eggert@twinsun.com>
        and Bruno Haible  <haible@clisp.cons.org>

        * quotearg.c (mbrtowc):
        Assign to *pwc, and return 1 only if result is nonzero.
        (iswprint): Use ISPRINT when substituting our own mbrtowc.

2000-07-03  Jim Meyering  <meyering@lucent.com>

        * readutmp.h: [HAVE_UTMPX_H]: Include <utmp.h> if HAVE_UTMP_H.
        This is necessary to get a definition of e.g., UTMP_FILE on HP-UX 10.20.
        From Bob Proulx.

2000-07-02  Jim Meyering  <meyering@lucent.com>

        * quotearg.c (mbstate_t): Don't define here.

2000-07-02  Jim Meyering  <meyering@lucent.com>

2000-06-29  Jim Meyering  <meyering@lucent.com>

        * same.c: Include <string.h> or <strings.h>, as appropriate,
        for declaration of strcmp.

        * long-options.c: Include <stdlib.h>, for declaration of exit.

        * mountlist.c (fsp_to_string) [HAVE_F_FSTYPENAME_IN_STATFS]:
        Avoid warning by casting result to `char *' to remove `const'.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * Makefile.am (libfetish_a_SOURCES): Remove readutmp.c.

2000-06-26  Paul Eggert  <eggert@twinsun.com>

        savedir now sets errno on failure and invokes xmalloc to get memory.
        Fix a couple of other minor bugs while we're at it.

        (NAMLEN): Remove macro.
        (malloc, realloc): Remove decls.
        (stpcpy): Likewise.
        ("xalloc.h"): Include.
        (NAME_SIZE_DEFAULT): New macro.
        (savedir): Use xmalloc / xrealloc to allocate memory.
        Use NAME_SIZE_DEFAULT if name_size is negative or overflows to zero.
        Skip "" directory entries.
        Use strlen to calculate directory entry length, since the old method
        is rarely used these days and isn't worth supporting.
        Don't use a pointer after freeing it.
        Check for integer overflow when calculating allocation size.
        Use memcpy to copy entries, instead of stpcpy.
        Set errno properly when returning NULL.
        Check for readdir error.

2000-06-26  Jim Meyering  <meyering@lucent.com>

        * xgetcwd.c (xgetcwd): If the required pathname length is smaller
        than 1024, return a memory chunk of least possible size, instead
        of size PATH_MAX + 2. In the loop, increment the size proportionally.
        Use free/xmalloc instead of xrealloc to avoid copying for very long
        paths.

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * canon-host.c (canon_host): Use malloc and memcpy to copy an

        * getstr.c (getstr): New file, extracted from getline.c, with
        the following changes: new parameter, delim2; both delim[12]

        * getstr.h: New file.

2000-06-19  Jim Meyering  <meyering@lucent.com>

        * getloadavg.c [HAVE_NLIST_H] (NLIST_STRUCT): Define.

2000-06-18  Jim Meyering  <meyering@lucent.com>

        * mkdir.c: Remove file, due mainly to copyright incompatibility.
        Besides, these days every porting target provides a mkdir function.

        (hash_delete): Rewrite to use neither the assignment operator
        nor the comma operator in an if-expression.

2000-05-15  Paul Eggert  <eggert@twinsun.com>

        * closeout.c:

        Remove; no longer needed.
        "quotearg.h": Add include.

        efficient on some hosts.
        (close_stdout_status): Remove test as to whether stdout was already
        closed; it breaks for the case "echo x | sort >&-".

        the definition of it to rpl_strftime also defined-away the system's
        declaration.

2000-04-15  Jim Meyering  <meyering@lucent.com>

        Use `C' to denote so-called `contiguous' files, the same way

2000-03-07  Paul Eggert  <eggert@twinsun.com>

        * savedir.c (savedir): Work even if directory size is

2000-03-06  Jim Meyering  <meyering@lucent.com>

        * localcharset.c (get_charset_aliases): Don't try to free file_name
        if it's NULL (because we ran out of memory).  From Bruno Haible.

        concatenation.

        * unicodeio.h (PARAMS): Define.
        Use it to guard prototype.

        * Makefile.am (install-exec-local): Create $(libdir) before installing
        into it.
        (uninstall-local): Uncomment this rule so `make distcheck' works

        (quotearg_buffer_restyled): Use it.

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * strtoumax.c: Fix typo in decl of strtoul: s/long long/long/.
        Guard declaration of strtoull also with `&& HAVE_UNSIGNED_LONG_LONG'.

        * backupfile.c: Guard inclusion of stdlib.h with `#if HAVE_STDLIB_H',
        not `#if STDC_HEADERS'.
        Declare malloc if needed.

        * backupfile.c: Use `#if !HAVE_DECL...' instead of `#ifndef HAVE_DECL..'
        now that autoconf always defines the HAVE_DECL_ symbols.
        * human.c: Likewise.
        * same.c: Likewise.
        * strtoumax.c: Likewise.

        * backupfile.c: Arrange for cpp to fail if the configure-time

        (tSNUMBER, tUNUMBER): Now of type <textintval>.
        (date, number, to_year): Use width of number in digits, not its value,
        to determine whether it's a 2-digit year, or a 2-digit time.

        Reported by John Kendall.

        (parser_control): Changed from struct parser_control to typedef (for

2000-02-14  Paul Eggert  <eggert@twinsun.com>

        adapted from changes to grep getpagesize.h by Martin P.J. Zinser.

2000-02-12  Jim Meyering  <meyering@lucent.com>

        * userspec.c (ISDIGIT): Define it.
        (isdigit): Remove definition.
        (is_number): Use ISDIGIT, not isdigit.
        <libintl.h>: Include.
        (_ and N_): Define.
        (parse_user_spec): Mark translatable strings.

2000-02-10  Jim Meyering  <meyering@lucent.com>

        With these changes, nanosleep.[ch] are finally enough like the other
        lib/* replacement files to compile on a few more losing systems.

        * nanosleep.h: Don't include config.h.
        Remove prototype from declaration of nanosleep.
        (PARAMS): Remove now-unneeded definition.
        * nanosleep.c: #undef nanosleep.
        (rpl_nanosleep): Rename from nanosleep.

2000-02-03  Jim Meyering  <meyering@lucent.com>

        * readutmp.c (read_utmp): Guard with `#ifdef UTMP_NAME_FUNCTION',
        rather than with `#if HAVE_UTMPNAME'.

2000-02-01  Jim Meyering  <meyering@lucent.com>

        * readutmp.h (UT_USER): Add parens.  From Andreas Schwab.

2000-01-31  Jim Meyering  <meyering@lucent.com>

        * nanosleep.h (nanosleep): Guard declaration with
        `#if ! HAVE_DECL_NANOSLEEP'.
        Without this, OFS gets a redeclaration error for rpl_nanosleep, due to
        the declaration in that vendor's sys/timers.h.
        Reported by Christian Krackowizer.

        * quotearg.c (ISASCII): Add #undef and move definition to follow
        inclusion of wctype.h to work around Solaris 2.6 namespace pollution.
        (ISPRINT): Likewise.
        Reported by Tom Tromey.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding
        uses of ->ut_name.  The latter doesn't work with new Linux header files
        where only utmpx.ut_user is declared.

        * readutmp.h (UT_USER): Define.

2000-01-23  Jim Meyering  <meyering@lucent.com>

        * Makefile.am (libfetish_a_SOURCES): Remove explicit mention of
        obstack.c.

2000-01-22  Jim Meyering  <meyering@lucent.com>

        * strtoumax.c: [! HAVE_DECL_STRTOUL]: Declare strtoul.
        [! HAVE_DECL_STRTOULL]: Declare strtoull.
        Required for some AIX systems.  Reported by Christian Krackowizer.

        * dirname.c (dir_name): Support for DOS-style file names with drive
        letters.

        * quotearg.c [HAVE_WCTYPE_H]: Include <wctype.h> for decl of iswprint.

        * strverscmp.c (ISDIGIT): Define.
        (strverscmp): Use ISDIGIT, not isdigit.

2000-01-17  Paul Eggert  <eggert@twinsun.com>

        * nanosleep.c (nanosleep):
        Don't use SA_INTERRUPT to decide whether to call sigaction, as
        POSIX.1 doesn't require SA_INTERRUPT and some systems
        (e.g. Solaris 7) don't define it.  Use SA_NOCLDSTOP instead;
        it's been part of POSIX.1 since day 1 (in 1988).

2000-01-17  Jim Meyering  <meyering@lucent.com>

        * interlock: Remove unused file.  Reported by François Pinard.

2000-01-16  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c (quotearg_buffer_restyled): Do not quote
        alert, backslash, formfeed, and vertical tab unnecessarily in
        shell quoting style.
