With this we can use this check in coreutils to find configure issues:
grep -E '(program exited with status 1$|core dumped)' config.log
* m4/mbrtowc.m4 (gl_MBRTOWC_C_LOCALE): Don't return 1
from the test program as this often indicates an
unhandled case in the test program.
(gl_MBRTOWC_INCOMPLETE_STATE): Likewise.
(gl_MBRTOWC_SANITYCHECK): Likewise.
(gl_MBRTOWC_NULL_ARG2): Likewise.
(gl_MBRTOWC_NUL_RETVAL): Likewise.
Fix mbrtowc so that it never returns -1 in the C locale,
as this conflicts with a future version of POSIX
http://austingroupbugs.net/view.php?id=663#c2738
and causes problems with GNU grep: http://bugs.gnu.org/23234

This is a fix for test breakage introduced by commit 45228d96; the
equality expression must be parenthesized when negated with '!',
otherwise we always get:
test-mbrtowc.c:49: assertion 'ret == (size_t)(-2)' failed
* m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): Negate the entire expression.
* m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): Likewise.
* m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): Don't return 1
from the test program as this is non standard and often
indicates an unhandled case in the test program.
* m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): Likewise.
Otherwise, Emacs might do the wrong thing if run in an
he_IL.ISO-8859-8 locale, which an Emacs developer does on occasion.
Problem reported by Eli Zaretskii in:
http://lists.gnu.org/archive/html/emacs-devel/2015-09/msg00966.html
Don't bother with test files, as they aren't copied to the Emacs
source directory. If this problem affects test files in some other
GNU project, we can add coding cookies to the non-ASCII test files
later.
* lib/mbrtowc.c (rpl_mbrtowc) [MBRTOWC_EMPTY_INPUT_BUG]: Fix the bug.
* m4/mbrlen.m4 (gl_MBRLEN_EMPTY_INPUT): New macro. It's not used,
so this is mainly for documentation.
* m4/mbrtowc.m4 (gl_MBRTOWC_EMPTY_INPUT): New macro.
(gl_FUNC_MBRTOWC): Use it.
* tests/test-mbrtowc.c (main): Test for the bug.
* m4/mbsinit.m4 (gl_FUNC_MBSINIT): If mbsinit is declared but not
defined, set REPLACE_MBSINIT.
* m4/mbrtowc.m4 (gl_FUNC_MBRTOWC): If mbrtowc is declared but not
defined, set REPLACE_MBRTOWC.
* m4/mbrlen.m4 (gl_FUNC_MBRLEN): If mbrlen is declared but not defined,
set REPLACE_MBRLEN.
* m4/mbsrtowcs.m4 (gl_FUNC_MBSRTOWCS): If mbsrtowcs is declared but not
defined, set REPLACE_MBSRTOWCS.
* m4/wcrtomb.m4 (gl_FUNC_WCRTOMB): If wcrtomb is declared but not
defined, set REPLACE_WCRTOMB.
* m4/wcsrtombs.m4 (gl_FUNC_WCSRTOMBS): If wcsrtombs is declared but not
defined, set REPLACE_WCSRTOMBS.
* m4/mbrtowc.m4 (gl_MBRTOWC_RETVAL): Detect native Windows bug. Use the
guess when no suitable locale for testing was found.
* doc/posix-functions/mbrtowc.texi: Mention the native Windows bug.
* m4/mbrtowc.m4 (gl_MBRTOWC_NULL_ARG1): New macro.
(gl_MBRTOWC_NULL_ARG2): Renamed from gl_MBRTOWC_NULL_ARG.
(gl_FUNC_MBRTOWC): Update. Define MBRTOWC_NULL_ARG2_BUG instead of
MBRTOWC_NULL_ARG_BUG. Invoke gl_MBRTOWC_NULL_ARG1 and define
MBRTOWC_NULL_ARG1_BUG.
* lib/mbrtowc.c (rpl_mbrtowc): Use MBRTOWC_NULL_ARG2_BUG instead of
MBRTOWC_NULL_ARG_BUG. Handle MBRTOWC_NULL_ARG1_BUG.
* tests/test-mbrtowc.c (main): Test support of a NULL first argument.
* doc/posix-functions/mbrtowc.texi: Mention the Solaris 7 bug.
99% of this change was performed by running the following commands:
git ls-files | grep '\.m4$' | xargs perl -pi \
-e 's/(AC_\w+\()([^[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){1})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){2})([^,[()]+?)([,)])/$1\[$2]$3/g;' \
-e 's/(AC_\w+\((?:\[[^,]+?\], ){3})([^,[()]+?)([,)])/$1\[$2]$3/g'
perl -pi -e 's/\[\.\.\.\]/.../' m4/onceonly.m4
The remainder were to add Copyright dates, increment serial numbers,
undo some changes in comments, exclude m4/intl.m4, and add quotes
around the "1" in ",1" where the unusual spacing prohibited the
above regexps from doing the job. For more details, see
<http://thread.gmane.org/gmane.comp.lib.gnulib.bugs/16175>.
