This merges in changes that were made to Autoconf master
in April 2024. It causes ‘configure’ to prefer the C compiler to
enable C23 features if possible; otherwise, ‘configure’
behaves as before, using C11 if available and C99 if not.
* admin/merge-gnulib (GNULIB_MODULES): Add std-gnu23.
(AVOIDED_MODULES): Add (i.e., start avoiding) std-gnu11.
* m4/std-gnu11.m4: Remove.
* m4/std-gnu23.m4: Add.
See https://lists.gnu.org/archive/html/emacs-devel/2025-11/msg00145.html
for the related discussions.
* nt/mingw-cfg.site (ac_cv_func_acl_entries): Set to "yes" to
disable compilation of lib/acl_entries.c on MinGW.
* lib/acl_entries.c (acl_entries): Revert last change, as it is no
longer needed.
* lib/acl_entries.c (acl_entries): Make it no-op for MinGW, as it
was before. Without this, acl_entries doesn't compile on MinGW.
* nt/gnulib-cfg.mk (OMIT_GNULIB_MODULE_issymlink)
(OMIT_GNULIB_MODULE_issymlinkat): Disable these Gnulib modules.
* admin/merge-gnulib (GNULIB_MODULES): Add stringeq.
With current Gnulib it is already present as in indirect dependency;
listing it here because Emacs now depends on it directly.
* lib-src/ebrowse.c, lib-src/etags.c:
(streq): Remove, as Gnulib defines this now.
* lib/fseterr.c, lib/fseterr.h, lib/issymlink.c, lib/issymlink.h:
* lib/issymlinkat.c, lib/stdio-consolesafe.c, lib/string.c:
* m4/fseterr.m4, m4/gettext_h.m4, m4/stringeq.m4:
New files from Gnulib.
* src/conf_post.h (tzfree) [__ANDROID_API__ >= 35]: Remove.
The following changes were made by hand,
so that admin/merge-gnulib could succeed
instead of failing because the diff didn’t match.
* admin/gnulib-patches/lib/getloadavg.c.diff:
Remove, as it is no longer needed now that recent
Gnulib has been merged.
* admin/merge-gnulib (GNULIB_TOOL_FLAGS):
Remove the --local-dir="$src"admin/gnulib-patches option,
as it is no longer needed either.
* admin/gnulib-patches/lib/getloadavg.c.diff: New file.
* admin/merge-gnulib (GNULIB_TOOL_FLAGS): Set --local-dir to
admin/gnulib-patches.
* lib/gnulib.mk.in: Update from Gnulib.
* lib/stdalign.in.h: Remove. This file was already removed in
commit b429274c5b (2023-02-04)
but was brought back mistakenly by a merge from emacs-29 in
commit ecf08f0621 (2024-01-02).
* nt/inc/stdalign.h: Don’t mention removed file in comment.
Instead of worrying about whether malloc and realloc yield a
non-null pointer when given size 0 (the traditional behavior
recommended by Doug McIlroy, and the only behavior that makes
sense for Emacs), let Gnulib arrange for the traditional behavior.
* admin/merge-gnulib (GNULIB_MODULES): Add malloc-gnu (which we
were already depending on indirectly) and realloc-posix.
* lib/gnulib.mk.in, m4/gnulib-comp.m4:
Regenerate by running admin/merge-gnulib.
Gnulib moved the prototypes of 'sig2str' and 'str2sig' from
sig2str.h to signal.h, but MinGW does not use the Gnulib
signal.h header, and doesn't have these functions in its
own signal.h.
* lib/sig2str.h (SIG2STR_MAX, sig2str, str2sig): Define and
prototype if not already defined.

The change in boot-time.c imported from Gnulib broke the
MinGW build using mingw.org's MinGW. It is wrong to include
sysinfoapi.h, MS documentation says to include <windows.h>.
* lib/boot-time.c: Don't include sysinfoapi.h.
