This release is being made mainly to cater to recent glibc changes in
light of the C23 language standard. However, it also includes fixes
for some corner-case bugs in eval and when using the defn macro on
builtins.
Fixes m4-native builds on hosts with glibc-2.43 like:
./stdlib.h:827:20: error: expected identifier or '(' before '_Generic'
./string.h:777:20: error: expected identifier or '(' before '_Generic'
Remove 0001-gettext-h-Avoid-gcc-Wformat-security-warnings-with-d.patch
which is included in gnulib revision used by m4 since:
https://gitweb.git.savannah.gnu.org/gitweb/?p=m4.git;a=commit;h=beee8d26382460010338c37f9dd9f823aa9f4ee8
LIC_FILES_CHKSUM was updated for barem4.m4 and testbarem4.m4 from:
https://gitweb.git.savannah.gnu.org/gitweb/?p=m4.git;a=blobdiff;f=examples/COPYING;h=e623b2b9394cbd1784a4964bbac105050296f33b;hp=7e73a1219b542fa035facc47cdb3dd81132e6373;hb=900a90f624cee4a8c1c02c4d6a61ef1ed26a17d1;hpb=c7b96d682958532c4eb2d5c2d81bb6ac342fd410

-Subject: [PATCH] gettext-h: Avoid gcc -Wformat-security warnings with
- --disable-nls.
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit

-Reported by Holger Hoffstätte <[email protected]> in
-<https://lists.gnu.org/archive/html/bug-gnulib/2025-05/msg00225.html>.
-
-* lib/gettext.h (gettext, dgettext, dcgettext): With gcc in C mode,
-define these as inline functions.
-* lib/sigpipe-die.c (sigpipe_die): Use translated string as a format
-string, relying on the format string checking done by 'msgfmt -c'.
-* lib/xmemcoll.c (collate_error): Revert commit from 2025-01-17.
-* lib/xprintf.c (xvprintf, xvfprintf): Likewise.
-* lib/openat-die.c (openat_save_fail, openat_restore_fail): Revert
-commit from 2024-12-10.
-
-Upstream-Status: Backport
