+ bootstrap: avoid failure when there is no .gitmodules file
+ ": ${gnulib_path=gnulib}" fails to set $gnulib_path when that variable
+ has been assigned to, even when its value is the empty string.
+ * build-aux/bootstrap (gnulib_path): Test explicitly for an empty
+ "$gnulib_path", rather than using ${gnulib_path=gnulib}.
+ Reported by John W. Eaton <jwe@gnu.org>.

+ assume <ctype.h>, ..., <time.h> exist
+ For years gnulib has been assuming the existence of the headers
+ <ctime.h>, <errno.h>, <fcntl.h>, <locale.h>, <signal.h>,
+ <stdio.h>, <stdlib.h>, <string.h>, and <time.h>. Omit checks for
+ them, since they don't appear to be needed.
+ * README (Portability guidelines): Document this.
+ * lib/flock.c: Assume <fcntl.h> exists.
+ * lib/regex_internal.h: Assume <locale.h> exists.
+ * m4/ctype.m4 (gl_CTYPE_H): Assume <ctype.h> exists.
+ * m4/errno_h.m4 (gl_HEADER_ERRNO_H): Assume <errno.h> exists.
+ * m4/fcntl_h.m4 (gl_FCNTL_H): Assume <fcntl.h> exists.
+ * m4/flock.m4 (gl_PREREQ_FLOCK): Likewise.
+ * m4/locale_h.m4 (gl_LOCALE_H): Assume <locale.h> exists.
+ * m4/regex.m4 (gl_REGEX): Likewise.
+ * m4/signal_h.m4 (gl_SIGNAL_H): Assume <signal.h> exists.
+ * m4/stdio_h.m4 (gl_STDIO_H): Assume <stdio.h> exists.
+ * m4/stdlib_h.m4 (gl_STDLIB_H): Assume <stdlib.h> exists.
+ * m4/string_h.m4 (gl_STRING_H): Assume <string.h> exists.
+ * tests/test-argp.c: Likewise.
+ * m4/time_h.m4 (gl_HEADER_TIME_H_BODY): Assume <time.h> exists.
+
+ multiarch: remove AA_APPLE_UNIVERSAL_BUILD
+ * m4/multiarch.m4 (gl_MULTIARCH): Don't AC_DEFINE
+ AA_APPLE_UNIVERSAL_BUILD. See
+ <http://lists.gnu.org/archive/html/bug-gnulib/2011-01/msg00247.html>.
+ * NEWS: Document this.

+ c-stack: assume stack overflow if SA_SIGINFO unsupported
+ * lib/c-stack.c (SIGACTION_WORKS): Rename...
+ (SIGINFO_WORKS): ...since gnulib module guarantees that (most) of
+ sigaction will work.
+ (die): Assume stack overflow if siginfo doesn't work, to let Haiku
+ behavior match Linux.
+ * tests/test-c-stack.c (main): Prefer NULL for pointers.
+
+ stdbool-tests: accomodate Haiku
+ * tests/test-stdbool.c: Haiku's gcc 2.95 lacks native _Bool.
+
+ binary-io: fix O_TEXT on Haiku
+ * modules/binary-io (Depends-on): Add fcntl-h.
+ * lib/binary-io.h (O_TEXT): Rely on replacement <fcntl.h> rather
+ than blindly undefining O_TEXT.
+ Reported by Scott McCreary.

+
+ include_next: do not check for standard headers like stddef.h
+
+ I found this problem when modifying Emacs to use gnulib.
+ I noticed that it added HAVE_STDDEF_H to config.h, even though
+ gnulib always assumes <stddef.h> exists as per README and this
+ symbol is unnecessary.
+ * m4/include_next.m4 (gl_NEXT_HEADERS): New macro, which does not
+ use AC_CHECK_HEADERS_ONCE, but which otherwise contains what
+ gl_CHECK_NEXT_HEADERS used to contain. This makes 'configure' run
+ faster for headers like stddef.h that are known to exist.
+ (gl_CHECK_NEXT_HEADERS): Use it.
+ * m4/float_h.m4 (gl_FLOAT_H): For float.h, use gl_NEXT_HEADERS
+ rather than gl_CHECK_NEXT_HEADERS.
+ * m4/stdarg.m4 (gl_STDARG_H): Likewise, for stdarg.h.
+ * m4/stddef_h.m4 (gl_STDDEF_H): Likewise, for stddef.h.
