[pspp] / lib / ChangeLog

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.

2004-03-30  Bruno Haible  <bruno@clisp.org>

        * 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.

        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.

        * 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>

        (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>

        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,

        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.

            Bruno Haible  <bruno@clisp.org>

        * printf-parse.h: Don't include sys/types.h.

        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>

        (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.

        (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

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

2003-09-25  Jim Meyering  <jim@meyering.net>
            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>

        * fatal-signal.h: New file, from GNU gettext.
        * fatal-signal.c: New file, from GNU gettext.

2003-10-04  Karl Berry  <karl@gnu.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.

2003-09-26  Jim Meyering  <jim@meyering.net>

        * error.c (error_tail): Move some declarations
        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.

2003-09-25  Bruno Haible  <bruno@clisp.org>

        * version-etc-2.h: New file, from version-etc.h with modifications.
        * version-etc-2.c: New file, from version-etc.c with modifications.

2003-09-25  Simon Josefsson  <jas@extundo.com>

        * xgetdomainname.h: New file.

            Bruno Haible  <bruno@clisp.org>

        * getdomainname.h: New file.
        * getdomainname.c: New file.

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

        * linebuffer.c (freebuffer): Don't free the argument, just
        the buffer associated with the argument.  Bug reported by
        Simon Josefsson.

2003-09-19  Karl Berry  <karl@gnu.org>

        * 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.
        * fwriteerror.c: New file.

2003-09-14  Jim Meyering  <jim@meyering.net>

        * getloadavg.c: Correct cpp indentation.
        * strdup.c: Likewise.
        * vasnprintf.c: Likewise.

2003-09-12  Paul Eggert  <eggert@twinsun.com>

        * argmatch.c, fatal.c, xgethostname.c, xmalloc.c: Include exit.h.
        * obstack.c [!defined _LIBC]: Likewise.
        * argmatch.c (EXIT_FAILURE): Remove; now done by exit.h
        * exitfail.c, fatal.c, xgethostname.c, xmalloc.c: Likewise.
        * exitfail.c: Don't include stdlib.h; no longer needed.

        More changes to assume C89 or better.

        * error.c (error_tail): Assume vprintf.

2003-08-19  Bruno Haible  <bruno@clisp.org>

        * xstrdup.c: Assume <string.h> exists.

2003-08-18  Jim Meyering  <jim@meyering.net>

        * regex.h, strdup.c, strtoll.c, strtoul.c: Do not normalize white
        space, undoing this 2003-08-12 change:
        <http://mail.gnu.org/archive/html/bug-gnulib/2003-08/msg00080.html>

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
        for credits and details.  Thanks to Kaveh Ghazi for helping

        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.

        (IN_CTYPE_DOMAIN): New macro.
        (is_space): New fn.
        (add_exclude_file): If LINE_END is a space, ignore trailing spaces
        and empty lines.

        * argp-help.c, argp-parse.c, config.charset, getopt.h:
        Undo previous (whitespace-only) change.

2003-08-12  Paul Eggert  <eggert@twinsun.com>

        * argp-help.c, argp-parse.c, config.charset, getopt.h:
        Normalize leading white space and remove trailing white space.

        * euidaccess.c: Include it.
        * .cppi-disable: Add printf-args.h, printf-parse.h, stdbool_.h,
        vasnprintf.h, vasprintf.h.  Remove strdup.c, gettext.h.
        * regex.h, strdup.c, strtoll.c, strtoul.c: Normalize white space.

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

        * vasnprintf.c (local_wcslen): New function, for Solaris 2.5.1.
        (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>

        GNU coding style.

        Merge from coreutils.
        * error.c [!USE_IN_LIBIO]: Omit this case; assume USE_IN_LIBIO is 1.
        From glibc.
        * getdate.y (date): Also accept dates like May-23-2003; suggestion
        from Karl Berry, implemented by Jim Meyering.
        * getgroups.c: Include "xalloc.h" instead of declaring xalloc fns;
        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.
        (xalloc_die): Use exit_failure instead of xalloc_exit_failure.
        * xmemcoll.h (xmemcoll_exit_failure): Remove.
        * xmemcoll.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.

2003-07-18  Bruno Haible  <bruno@clisp.org>

        * getndelim2.h: New file.
        * getndelim2.c: Make into a module of its own. Include config.h,
        getndelim2.h.
        (getndelim2): Make non-static. Change return type to ssize_t.
        * getline.h: Change argument names.
        * getline.c: Include getndelim2.h instead of getndelim2.c.
        * getnline.c: Include getndelim2.h.

        * getnline.h: New file.
        * getnline.c: New file.
        * getndelim2.c: New file, extracted from getline.c.
        (getndelim2): Renamed from getdelim2, with added nmax argument.
        * getline.c: Include getndelim2.c.

2003-07-15  Jim Meyering  <jim@meyering.net>

        * makepath.c (make_path): Enclose diagnostic in _(...).

2003-07-14  Paul Eggert  <eggert@twinsun.com>

        * asnprintf.c, asprintf.c, config.charset, gettext.h,
        localcharset.c, localcharset.h, mkdtemp.c, printf-args.c,
        printf-args.h, printf-parse.c, printf-parse.h, ref-add.sin,
        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.

2003-07-14  Paul Eggert  <eggert@twinsun.com>

        * ceill.c, expl.c, floorl.c, frexpl.c, ldexpl.c, mathl.h,
        sincosl.c, sqrtl.c, trigl.c, trigl.h, poll.c, poll_.h, mkstemp.c,
        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>

        Assume C89, so PARAMS isn't needed.
        * unicodeio.h (PARAMS): Remove.
        * unicodeio.c: Don't use PARAMS.

2003-06-18  Jim Meyering  <jim@meyering.net>

2003-06-17  Paul Eggert  <eggert@twinsun.com>

        Assume C89, so PARAMS isn't needed.
        * backupfile.h (PARAMS): Remove.  All uses removed.
        * closeout.h, dirname.h, filemode.h, fsusage.h, getdate.h, getline.h,
        group-member.h, hard-locale.h, hash.h, linebuffer.h, long-options.h,

        unistd-safer.h, version-etc.h, xalloc.h, xreadlink.h, xstrtod.h,
        xstrtol.h: Likewise.
        * 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.

2003-06-11  Simon Josefsson  <jas@extundo.com>

        * sysexit_.h: New file.

2003-05-20  Derek Price  <derek@ximbiot.com>

        * readtokens.h: Put `Free Software Foundation, Inc.'
        in place of my name in the copyright comment.
        Remove definition and uses of __P.

        From coreutils.
        * stat.c: Don't declare xmalloc explicitly.
        Instead, include "xalloc.h".
        * readtokens.c (readtokens): Remove anachronistic casts of xmalloc,
        xrealloc, and xcalloc return values.
        * xgetcwd.c (xgetcwd): Include "xgetcwd.h".
        Improve comment.
        * xgetcwd.h: Remove definition/uses of PARAMS.

2003-06-06  Jim Meyering  <jim@meyering.net>

        * stdbool_.h: Renamed from stdbool.h.in.

2003-06-06  Jim Meyering  <jim@meyering.net>

        Merge from coreutils.
        * same.c: (same_name): Declare *_basename locals to be `const'.
        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.
        * fsusage.c: Remove declaration of statfs.
        It conflicted with one from OSF/1 5.1 in <sys/mount.h>.

        * posixtm.c: Include <stdbool.h> unconditionally.

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.
        (__P): Remove; not used.
        (CHAR_BIT, INT_MIN, INT_MAX): Remove; <limits.h> defines them.
        (mktime, not_equal_tm, print_tm, check_result,
        main): Use prototypes.  Use const * where appropriate.
        (main): Fix typo in testing code that uncovered by above changes.
        (Local Variables): Remove -DHAVE_LIMITS_H from compile-command.

2003-06-04  Paul Eggert  <eggert@twinsun.com>

        * mktime.c: Fix Debian bug 177940
        <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.
        Include human.h immediately after config.h.
        <sys/types.h>, <stdio.h>: Do not include; no longer needed.
        <limits.h>: Do not include, since human.h does.
        (SIZE_MAX, UINTMAX_MAX): New macros.
        <strings.h>: Include if HAVE_STRINGS_H, not if !HAVE_STRING_H.
        <locale.h>: Include if HAVE_LOCALE_H and HAVE_LOCALECONV.
        (HUMAN_READABLE_SUFFIX_LENGTH_MAX): New macro.
        (power_letter): Renamed from suffixes.
        (generate_suffix_backwards): Remove.
        (adjust_value): Now takes int style (because of human.h changes)
        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.
        * localcharset.h: Likewise.
        * localcharset.c: Likewise.

2003-05-28  Paul Eggert  <eggert@twinsun.com>

        Assume the headers required for C89 freestanding compilers.
        * addext.c, backupfile.c, fsusage.c, human.c, pathmax.h,
        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
        the space-padded-by-default conversion specifiers, %e, %k, %l.

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

        Upgrade to Unicode-4.0.
        * linebreak.c (nonspacing_table_data): Change width of U+00AD,
        U+0350..U+0357, U+035D..U+035F, U+0600..U+0603, U+0610..U+0615,

        U+17DD, U+1920..U+1922, U+1927..U+192B, U+1932, U+1939..U+193B
        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.

2003-04-25  Jim Meyering  <jim@meyering.net>

        * copy-file.c (copy_file_preserving): Declare buf_size to be
        of type size_t, not int.

        Merge changes from Coreutils.

        2003-03-22  Jim Meyering  <jim@meyering.net>

        * strftime.c (widen): Cast alloca return value to proper type.

        2003-01-19  Ulrich Drepper  <drepper@redhat.com>

        From GNU libc.
        * strftime.c (my_strftime): Handle very large width
        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.

        Add test-cases for DOS filenames. Declare program_name.

        * 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.

        From Volker Borchert.

2002-06-11  Paul Eggert  <eggert@twinsun.com>

        * fnmatch.c, fnmatch_loop.c (WIDE_CHAR_SUPPORT):
        New macro.  Use it uniformly instead of
        (defined HAVE_WCTYPE_H && defined HAVE_WCHAR_H).
        It also uses HAVE_BTOWC, to fix a porting bug on Solaris 2.5.1
        reported by Vin Shelton.

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * fnmatch.c (ISASCII, ISPRINT): Undefine, to avoid warning about
        redefinition due to Solaris 2.6's definition in /usr/include/sys/euc.h.

2002-06-22  Paul Eggert  <eggert@twinsun.com>

        * c-stack.h (segv_handler, c_stack_action) [! defined SA_SIGINFO]:
        Do not assume SA_SIGINFO behavior.
        Bug reported by Jim Meyering on NetBSD 1.5.2.

2002-06-22  Jim Meyering  <meyering@lucent.com>

        * c-stack.c, c-stack.h: New files, from diffutils-2.8.2.

        * exitfail.c, exitfail.h: Likewise.
        * Makefile.am (libfetish_a_SOURCES): Add exitfail.c and exitfail.h.

        * fnmatch.h: Remove file.

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.

        * 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>

2002-04-12  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.

2002-02-24  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.

        (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.

        All callers changed.
        (quoting_options_from_style): 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.

        have nothing pending.

2001-12-18  Paul Eggert  <eggert@twinsun.com>

        See the big note in ../ChangeLog.

        (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,

        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.

        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.

        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.

        * 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.
        * Makefile.am (libfetish_a_SOURCES): Add dirfd.h.

        * hash.c (hash_print) [TESTING]: Clean up.

2001-10-22  Paul Eggert  <eggert@twinsun.com>

        * hard-locale.c (alloca): Define to __builtin_alloca if __GNUC__,
        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.
        * gtod.h: New file.
        * Makefile.am (libfetish_a_SOURCES): Add gtod.h.

2001-08-04  Jim Meyering  <meyering@lucent.com>

        * error.h (__attribute__): Remove `|| __STRICT_ANSI__' from #if stmt,
        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.

        recommendation.
        (libfetish_a_SOURCES): Put all .h files here instead.
        Remove a thus-exposed (better checks in automake) duplicate and
        two unnecessary .h files.

2001-06-11  Jim Meyering  <meyering@lucent.com>

        * regex.c: Update from GNU libc.

2001-05-27  Jim Meyering  <meyering@lucent.com>

2001-05-24  Jim Meyering  <meyering@lucent.com>

        * argmatch.c: Include "quote.h".
        (argmatch_invalid): Remove explicit `' quotes.  Instead, use the
        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>

        * Makefile.am (libfetish_a_SOURCES):
        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
        ut_argument, ut_argument_spec, ut_argument_spec_iso, respectively.

        (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.

        * 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.

2001-03-13  Jim Meyering  <meyering@lucent.com>

        * path-concat.c (path_concat) [FILESYSTEM_ACCEPTS_DRIVE_LETTER_PREFIX]:
        Don't insert a backslash when concatenating e.g., `C:' and `foo'.
        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.

        support for DOS/DJGPP.

2001-02-28  Paul Eggert  <eggert@twinsun.com>

        * Makefile.am (libfetish_a_SOURCES):
        Add dup-safer.c, fopen-safer.c.

2001-02-25  Paul Eggert  <eggert@twinsun.com>

        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.

        * tempname.c (<config.h>): Include if HAVE_CONFIG_H.
        (<stddef.h>, <stdint.h>, <string.h>):
        Include only if STDC_HEADERS || _LIBC.
        (<fcntl.h>): Include only if HAVE_FCNTL_H || _LIBC.
        (<unistd.h>): Include only if HAVE_UNISTD_H || _LIBC.
        (<sys/time.h>): Include only if HAVE_SYS_TIME_H || _LIBC.
        (__set_errno): Define this macro if <errno.h> doesn't.
        (P_tmpdir, TMP_MAX, __GT_FILE, __GT_BIGFILE, __GT_DIR, __GT_NOCREATE):
        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.
        (stat64, __getpid, __gettimeofday, __mkdir, __open, __open64, lxstat64,
        __xstat64): Define if not _LIBC.
        (__secure_getenv): Define if ! (HAVE___SECURE_GETENV || _LIBC).
        (__gen_tempname): Invoke gettimeofday only if
        HAVE_GETTIMEOFDAY || _LIBC;
        otherwise, fall back on plain "time".
        Use macros like S_IRUSR | S_IWUSR rather than octal values like 0600.

        * mkstemp.c (__GT_FILE): Define to zero if not defined.

        * mkstemp.c, tempname.c: New files, taken from glibc 2.2.2.

        around included file name.

        * strnlen.c (__strnlen): Merge in a change from GNU libc.

        * strftime.c: Update from GNU libc (the only changes were to comments).

2001-02-13  Bruno Haible  <haible@clisp.cons.org>

        * mbswidth.h (mbswidth): Also define as macro, to avoid prototype clash.

2001-02-17  Paul Eggert  <eggert@twinsun.com>

        * mbswidth.c, quotearg.c (mbrtowc, mbsinit):
        Remove workaround macros for hosts that have mbrtowc but not
        mbstate_t, as we now insist on proper declarations for both
        before using mbrtowc.

2001-02-17  Jim Meyering  <meyering@lucent.com>

        * regex.c: Update from libc.

2001-02-16  Paul Eggert  <eggert@twinsun.com>

        * alloca.c (malloc): Undef before defining, since stdlib.h
        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>

        [HAVE_DONE_WORKING_REALLOC_CHECK]: Likewise.
        Reported by Axel Kittenberger.

2001-01-15  Bruno Haible  <haible@clisp.cons.org>

        * unicodeio.c (print_unicode_char): Cast the second iconv() arg,

2001-01-16  Jim Meyering  <meyering@lucent.com>

        * basename.c: Include <stdio.h>, needed by assert on SunOS 4.
        From Bruno Haible.

2001-01-14  Jim Meyering  <meyering@lucent.com>

        Include stdlib.h, string.h or strings.h, and xalloc.h.
        Use strip_trailing_slashes rather than open-coding it.

2001-01-03  Paul Eggert  <eggert@twinsun.com>

        * strftime.c: Sync with glibc time/strftime.c 1.81.

        * unicodeio.c (print_unicode_char): Remove `const' from declaration of
        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>

        * dirname.c (dir_name_r): Add `const' in a few local declarations.

2000-12-04  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>

        * memrchr.c: Include <config.h> before any system include file.

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>

2000-11-06  Paul Eggert  <eggert@twinsun.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>

        * xstat.in: Fix grammar in comment.

2000-10-28  Jim Meyering  <meyering@lucent.com>

        Adjust for portability:
        [HAVE_STDLIB_H]: Include stdlib.h.
        [HAVE_BP_SYM_H || _LIBC]: Guard inclusion of bp-sym.h.
        Undef __memchr, too.

        * regex.c: Update from libc.
        * regex.h: Likewise.
        * getopt1.c: Likewise.
        * memcmp.c: Likewise.

        * getusershell.c (setusershell) [HAVE_FSEEKO]: Use fseeko.
        Avoid using fseek, when possible -- it's broken by design.
        Patch by Ulrich Drepper.

2000-10-26  Jim Meyering  <meyering@lucent.com>

        * strftime.c: Update from libc.

2000-10-25  Jim Meyering  <meyering@lucent.com>

        * obstack.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.
        [CYCLIC]: Remove now-unused definition.

        * save-cwd.c (O_DIRECTORY): Define, if needed.
        (save_cwd) [HAVE_FCHDIR]: Use O_DIRECTORY when opening ".".
        Suggestion from Ulrich Drepper.

        * dirname.c (memrchr): Declare if necessary.
        (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>

        * quote.h (PARAMS): Define and use.

2000-09-25  Jim Meyering  <meyering@lucent.com>

        * md5.h (rol): Define (from GnuPG).

        * sha.c: Give credit (GnuPG) where due.
        (M): Use rol rather than open-coding it.
        Add a FIXME comment.

2000-09-21  Jim Meyering  <meyering@lucent.com>

        * userspec.c (parse_user_spec): Remove debugging printf I'd added.

        * Makefile.am (libfetish_a_SOURCES): Add sha.c.
        (noinst_HEADERS): Add sha.h.
        Based on code from Scott G. Miller and from GnuPG.

2000-09-15  Jim Meyering  <meyering@lucent.com>

2000-09-10  Jim Meyering  <meyering@lucent.com>

        * getopt.c (_getopt_internal): Update from glibc.

2000-09-09  Jim Meyering  <meyering@lucent.com>

        * quotearg.c: Rename ISASCII to IN_CTYPE_DOMAIN, so people don't
        think it should be used as a general replacement for isascii.
        * fnmatch.c: Likewise.
        * mbswidth.c: Likewise
        * regex.c: Likewise.

        Don't use atoi.
        * userspec.c: Include sys/param.h and limits.h.

        (CHAR_BIT, TYPE_SIGNED, TYPE_MINIMUM, TYPE_MAXIMUM): Define.
        (UID_T_MAX, GID_T_MAX, MAXUID, MAXGID): Define.

        * Makefile.am (noinst_HEADERS): Add __fpending.h.
        * __fpending.c: New file.
        * __fpending.h: New file.

2000-08-07  Paul Eggert  <eggert@twinsun.com>

        Standardize on "memory exhausted" instead of "Memory exhausted"
        or "virtual memory exhausted".
        * obstack.c (print_and_abort): Use "memory exhausted", not
        "virtual memory exhausted".
        * same.c (same_name): Invoke xalloc_die instead of printing
        our own message.
        * userspec.c (parse_user_spec): Likewise.
        * bumpalloc.h: comment fix
        * same.c, userspec.c: Include xalloc.h.

        * xalloc.h (xalloc_msg_memory_exhausted): Now char const[],

2000-08-03  Greg McGary  <greg@mcgary.org>

        * regex.c (SET_HIGH_BOUND, MOVE_BUFFER_POINTER,
        ELSE_EXTEND_BUFFER_HIGH_BOUND): New macros.
        (EXTEND_BUFFER): Use them.

2000-08-01  Jim Meyering  <meyering@lucent.com>

        * dirname.c (ISSLASH): Define.
        (BACKSLASH_IS_PATH_SEPARATOR): Define.
        (dir_name) [BACKSLASH_IS_PATH_SEPARATOR]: Handle the case in which
        both `\' and `/' may be use as path separators.
        Based on a patch from Prashant TR.

2000-07-31  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c (quotearg_n_options): Don't make the initial
        slot vector a constant, since it might get modified.

2000-07-31  Jim Meyering  <meyering@lucent.com>

        * xmalloc.c: Use `virtual memory exhausted', not `Memory exhausted'.
        * obstack.c (print_and_abort): Likewise.

2000-07-30  Paul Eggert  <eggert@twinsun.com>

        * quotearg.c (quotearg_n_options): Preallocate a slot 0
        buffer, so that the caller can always quote one small
        component of a "memory exhausted" message in slot 0.
        From a suggestion by Jim Meyering.

2000-07-30  Jim Meyering  <meyering@lucent.com>

        (STATIC_BUF_SIZE): Define.
        (quotearg_n_options): Use only statically allocated storage when
        N < N_STATIC_SLOTVECS and the length of the quoted result is smaller
        than STATIC_BUF_SIZE.

2000-07-29  Jim Meyering  <meyering@lucent.com>

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.

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>

        and IRIX 6.

2000-07-15  Jim Meyering  <meyering@lucent.com>

        * 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.

2000-07-03  Jim Meyering  <meyering@lucent.com>

        * strndup.c: [!HAVE_DECL_STRNLEN]: Declare strnlen.
        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>

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        (read_filesystem_list): Ignore symbolic links.

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.

        * savedir.c (<unistd.h>): Do not include; there's no need.
        (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
        address, not strdup.  Include <stdlib.h> and don't declare free().

2000-06-17  Bruno Haible  <haible@clisp.cons.org>

        * path-concat.c (path_concat): Don't access dir[-1] if dir is

        the following changes: new parameter, delim2; both delim[12]
        parameters have type `int', not `char'.  The latter would lose
        with 8-bit delimiters.
        * 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.

        * strnlen.c: Include memory.h, string.h, and/or strings.h as needed.
        (this snippet comes from src/system.h).

2000-06-15  Paul Eggert  <eggert@twinsun.com>

        * human.c (adjust_value): New function.
        (human_readable_inexact): Apply rounding style even when

        * human.c (human_readable_inexact): Allow an input block
        size that is not a multiple of the output block size, and vice versa.

        on glibc-2.1 or newer.

2000-06-02  Jim Meyering  <meyering@lucent.com>

        member using the same `ignore'-testing code.
        * mountlist.h (ME_DUMMY): Add `autofs' to the list of ignored

2000-05-18  Jim Meyering  <meyering@lucent.com>

        * hash.c (hash_rehash): Fix a nasty bug: copy the free entry list
        back, too, since it may have been modified by allocate_entry.
        (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:
        <sys/stat.h>, <sys/types.h>, <unistd.h>, (STDOUT_FILENO):
        Remove; no longer needed.
        "quotearg.h": Add include.
        (file_name): Do not bother to explicitly initialize to NULL; it's less
        efficient on some hosts.
        (close_stdout_status): Remove test as to whether stdout was already
        closed; it breaks for the case "echo x | sort >&-".
        Quote file name colons.

2000-05-15  Jim Meyering  <meyering@lucent.com>

        Use `C' to denote so-called `contiguous' files, the same way

        strftime, not ourselves, when invoking the underlying strftime.

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

2000-02-27  Jim Meyering  <meyering@lucent.com>

        * 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

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.

        Remove prototype from declaration of nanosleep.

        (rpl_nanosleep): Rename from nanosleep.

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.

        Reported by Tom Tromey.

2000-01-30  Jim Meyering  <meyering@lucent.com>

        * readutmp.c (extract_trimmed_name): Use UT_USER instead of hard-coding

        where only utmpx.ut_user is declared.

        * readutmp.h (UT_USER): Define.

2000-01-23  Jim Meyering  <meyering@lucent.com>

        (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>

        alert, backslash, formfeed, and vertical tab unnecessarily in
        shell quoting style.
