\| \| \| \| \| \| \| \| \|	Problem reported by Bruno Haible in: https://lists.gnu.org/r/bug-gnulib/2023-02/msg00098.html * doc/gnulib.texi (nullptr): Document limitations better. * m4/nullptr.m4 (gl_NULLPTR): Check for incompatibility of macOS clang 14.0.0 (clang-1400.0.29.202), where <stddef.h> defines a non-working nullptr macro.
*	Fix compilation errors in C++ mode on macOS 12.5.	Bruno Haible	2023-02-09	1	-2/+2
\| \| \| \| \| \|	* m4/gnulib-common.m4 (gl_COMMON_BODY): Don't define _GL_ATTRIBUTE_MAYBE_UNUSED to [[__maybe_unused__]] if the compiler is an Apple variant of clang.
*	limits-h: Work around a clang 15 bug.	Bruno Haible	2023-02-09	1	-0/+1
\| \| \| \| \|	* m4/limits-h.m4 (gl_LIMITS_H): Test also for BOOL_MAX. * doc/posix-headers/limits.texi: Mention the clang bug.

\| \| \| \| \|	* m4/assert_h.m4 (gl_ASSERT_H): Ensure that on IRIX, including <assert.h> after <config.h> actually defines the assert macro.
*	nullptr: test for compilers at autoconf-time	Paul Eggert	2023-02-07	1	-9/+19
\| \| \| \| \| \| \|	* m4/nullptr.m4 (gl_NULLPTR): Test for C and C++ compiler usage at autoconf-time. This should work better than testing at configure-time. Also, push and pop languages so we check the proper compiler.

\| \| \| \| \| \|	* m4/nullptr.m4 (gl_NULLPTR): Test for C++ support for nullptr at configure-time, as we already do for C support. This should be more reliable than maintaining #ifdefs by hand.
*	nullptr: rename from c-nullptr	Paul Eggert	2023-02-07	1	-1/+1
\| \| \| \| \| \| \| \| \| \|	* NEWS, doc/gnulib.texi: Mention this. * m4/nullptr.m4: Rename from m4/c-nullptr.m4.

\| \| \| \| \| \| \| \| \|	Reported by Bjarni Ingi Gislason <bjarniig@simnet.is> in <https://lists.gnu.org/archive/html/bug-gnulib/2023-02/msg00030.html>. * m4/c-nullptr.m4 (gl_C_NULLPTR): Don't define nullptr if it is already defined. In C++ mode, ignore the result of the configure test and don't define it when we know that the C++ compiler already supports it.
*	c-nullptr: new module	Paul Eggert	2023-02-05	1	-0/+30

*	Avoid clang warnings regarding [[__maybe_unused__]].	Bruno Haible	2023-01-28	1	-3/+9
\| \| \| \| \| \| \|	* m4/gnulib-common.m4 (gl_COMMON_BODY): For clang versions ≥ 6, < 10, in C++ mode, ignore the __has_c_attribute value and define _GL_ATTRIBUTE_MAYBE_UNUSED to __attribute__ ((__unused__)), not [[__maybe_unused__]].
*	alignasof: Ensure a correct _Alignof (regression 2023-01-15).	Bruno Haible	2023-01-28	1	-25/+30
\| \| \| \| \|	* m4/stdalign.m4 (gl_ALIGNASOF): Apply the workaround for wrong _Alignof in GCC < 4.9 and clang < 8.0.0 also when the system has <stdalign.h>.

\| \| \| \| \| \| \| \| \|	* lib/stdalign.in.h: Include the system's <stdalign.h> when it exists. * m4/stdalign.m4 (gl_ALIGNASOF): Invoke gl_CHECK_NEXT_HEADERS. Set HAVE_STDALIGN_H. * modules/stdalign (Makefile.am): Substitute GUARD_PREFIX, HAVE_STDALIGN_H, INCLUDE_NEXT, PRAGMA_SYSTEM_HEADER, PRAGMA_COLUMNS, NEXT_STDALIGN_H.

\| \| \| \| \|	* m4/stddef_h.m4 (gl_STDDEF_H): When testing for good max_align_t, use an ISO C compliant definition of _Alignof.
*	Keep config.h idempotent.	Bruno Haible	2023-01-25	1	-129/+181
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	* m4/gnulib-common.m4 (gl_COMMON_BODY): Add double-inclusion guards to the definitions of the macros _GL_ATTRIBUTE_ALLOC_SIZE, _GL_ATTRIBUTE_ALWAYS_INLINE, _GL_ATTRIBUTE_ARTIFICIAL, _GL_ATTRIBUTE_COLD, _GL_ATTRIBUTE_CONST, _GL_ATTRIBUTE_DEALLOC, _GL_ATTRIBUTE_DEPRECATED, _GL_ATTRIBUTE_ERROR, _GL_ATTRIBUTE_WARNING, _GL_ATTRIBUTE_EXTERNALLY_VISIBLE, _GL_ATTRIBUTE_FALLTHROUGH, _GL_ATTRIBUTE_FORMAT, _GL_ATTRIBUTE_LEAF, _GL_ATTRIBUTE_MALLOC, _GL_ATTRIBUTE_MAY_ALIAS, _GL_ATTRIBUTE_MAYBE_UNUSED, _GL_ATTRIBUTE_NODISCARD, _GL_ATTRIBUTE_NOINLINE, _GL_ATTRIBUTE_NONNULL, _GL_ATTRIBUTE_NONSTRING, _GL_ATTRIBUTE_NOTHROW, _GL_ATTRIBUTE_PACKED, _GL_ATTRIBUTE_PURE, _GL_ATTRIBUTE_RETURNS_NONNULL, _GL_ATTRIBUTE_SENTINEL, _GL_ATTRIBUTE_UNUSED, _GL_UNUSED_LABEL.
