for each problematic character C.

* lib/canonicalize.c: Include min-eloop-threshold.h.
(canonicalize_filename_mode_stk): Set errno to ELOOP and exit if we see
MIN_ELOOP_THRESHOLD links.
* modules/canonicalize (Depends-on): Add eloop-threshold.
* tests/test-canonicalize.c (main): Add a test case that would
previously loop until the system ran out of memory. Clean up the created
sylink.
* tests/test-malloc-posix.c (__has_feature): New macro.
(main): Skip the test if an address sanitizer is in use.
* tests/test-calloc-posix.c (__has_feature): New macro.
(main): Skip the test if an address sanitizer is in use.
* tests/test-reallocarray.c (__has_feature): New macro.
(main): Skip the test if an address sanitizer is in use.
* m4/wcrtomb.m4 (gl_FUNC_WCRTOMB): Require gl_MBRTOWC_C_LOCALE and, if
needed, set REPLACE_WCRTOMB and define MBRTOWC_IN_C_LOCALE_MAYBE_EILSEQ.
* lib/mbrtowc.c (rpl_mbrtowc) [MBRTOWC_IN_C_LOCALE_MAYBE_EILSEQ]: In the
C locale, map 0x80..0xFF to 0xDF80..0xDFFF instead of 0x0080..0x00FF.
* lib/wcrtomb.c: Include hard-locale.h, <locale.h>.
(wcrtomb) [MBRTOWC_IN_C_LOCALE_MAYBE_EILSEQ]: In the C locale, map
0xDF80..0xDFFF to 0x80..0xFF.
* modules/wcrtomb (Depends-on): Add hard-locale.
* tests/test-wcrtomb.c (main): Check that wcrtomb does the inverse of
mbrtowc in the C locale.
Suggested by Paul Eggert.
* m4/c32rtomb.m4 (gl_FUNC_C32RTOMB): Require gl_MBRTOC32_C_LOCALE,
gl_MBRTOC32_C_LOCALE_LIKE_ISO_8859. When mbrtoc32 gets overridden due to
the C locale, set also REPLACE_C32RTOMB to 1.
* lib/c32rtomb.c: Include hard-locale.h, <locale.h>.
(c32rtomb): On OpenBSD, NetBSD ≥ 11, glibc, Cygwin, mingw, MSVC, do
special handling of non-ASCII characters in the C locale.
* modules/c32rtomb (Depends-on): Add hard-locale.
* tests/test-c32rtomb.c (main): Check that c32rtomb does the inverse of
mbrtoc32 in the C locale.
I ran into some problems with GNU sed on NetBSD and
endeavored to fix some of them by altering the mbrtoc32 replacement,
so that in the C locale it always converts bytes with the top
bit set to 0xDFxx, instead of doing it only sometimes.
This patch also updates commentary to match current POSIX standards
and some newer OS releases.
* lib/mbrtoc32.c (mbrtoc32): Also convert (e.g.) 0xED to 0xDFED
when !GNULIB_defined_mbstate_t && HAVE_WORKING_MBRTOC32 &&
HAVE_WORKING_C32RTOMB && !MBRTOC32_MULTIBYTE_LOCALE_BUG &&
MBRTOC32_IN_C_LOCALE_MAYBE_EILSEQ.
* tests/test-mbrtoc16.c (main):
* tests/test-mbrtoc32.c (main):
Simplify, now that we always do that conversion.
On NetBSD 10.0 at least, since commit e4c911bb4, warn_() would
issue a warning like "local: set-up: bad variable name".
This is due to how its shell handles "local" with initialization.
* tests/init.sh: Avoid initializing on the same line as "local".
$ date-before -d '1-2-3' "+[%_D]"
[02/03/ 1]
$ date-after -d '1-2-3' "+[%_D]"
[02/03/01]
* lib/strftime.c: Only propagate flags to %F as that has the
year at the start so our current "yearish" based flag propagation
produces consistent results. Specifically this avoids glibc
'_' and '-' flags propagating to year sub specifiers of %D,
producing inconsistent year and month/date formatting.
* tests/test-nstrftime.h: Add test cases.
* tests/test-sd-dlopen.c: New file.
* tests/test-sd-dlopen-disabled.c: New file.
* tests/test-sd-dlopen.sh: New file.

* lib/gettext.h (textdomain, bindtextdomain, bind_textdomain_codeset)
[!ENABLE_NLS && __GNUC__ && !__clang__ && !__cplusplus]:
Define to no-ops in this case too.
Move the definition of _LIBGETTEXT_FUNCAST up one level of
ifdeffery so that it is defined for this case.
* tests/test-gettext-h.c (main) [!ENABLE_NLS]: Call textdomain,
reverting the previous change to this file.
* tests/test-wmemcpy.c (null_wmemcpy, main): Move the #if and comment
from null_wmemcpy to main to avoid invoking undefined behavior.
* tests/test-wmemmove.c (null_wmemmove, main): Likewise.

New macros.
(excluded_file_name): New function.
* tests/test-exclude.c (main): Test new function too.
All test scripts changed.
* tests/test-sameacls.c (main): AIX 7.3’s aclx_* APIs want char *

preprocessor-time check, not a potentially runtime check, to see

Include <limits.h> to get ULONG_MAX.
Test that the compiler doesn't optimize a NULL check away when it sees
the prototypes in the headers <string.h>, <wchar.h>, and <stdlib.h>.
The existing tests explicitly avoided the effects of the attributes
in the function prototypes.
Exclude GCC < 15 and glibc which are known to be problematic.
Use 2.99 as a placeholder for a fixed glibc version. It should
be updated once the glibc headers have been changed.
