Problem reported by Karl Berry in:
https://lists.gnu.org/r/bug-gnulib/2022-11/msg00004.html
* build-aux/depcomp, doc/make-stds.texi, lib/malloc/scratch_buffer.h:
Autoupdate.
* build-aux/install-reloc (func_create_wrapper):
Omit removed file scratch_buffer_dupfree.c.
* config/srclist.txt: Remove lib/malloc/scratch_buffer_dupfree.c
* lib/canonicalize-lgpl.c: Merge changes from glibc through its
commit ef0700004bf0dccf493a5e8e21f71d9e7972ea9f dated 2022-07-05
11:04:45 +0200.
(__strdup) [!_LIBC]: New macro.
(struct realpath_bufs): New type.
(realpath_stk): Use it as the extra argument. All uses changed.
No longer any need for noinline or GCC_BOGUS_WRETURN_LOCAL_ADDR.
* lib/canonicalize.c (struct realpath_bufs)
(canonicalize_filename_mode_stk): Likewise.
* lib/malloc/scratch_buffer_dupfree.c:
Remove, since it was removed in glibc.
* lib/scratch_buffer.h (scratch_buffer_dupfree) [0]:
(__libc_scratch_buffer_dupfree): Remove decls.
* modules/relocatable-prog-wrapper (Files):
* modules/scratch_buffer (Files, lib_SOURCES):
Remove lib/malloc/scratch_buffer_dupfree.c.
This also helps document glibc’s direction in using GCC’s
memory-allocation checking.
* lib/cdefs.h: Omit comments that glibc rejected.
(__returns_nonnull, __attr_access_none, __attr_dealloc)
(__attr_dealloc_free): New macros.
* lib/libc-config.h: Undef the new macros that are defined
unconditionally.
* lib/malloc/dynarray_at_failure.c [_LIBC]: Do not include stdlib.h.
(__libc_dynarray_at_failure) [_LIBC]: Call __libc_fatal,
fixing a bad merge previously.
DragonFlyBSD defines __nonnull incompatibly with glibc,
so avoid the use of __nonnull in Gnulib code.

https://lists.gnu.org/r/bug-gnulib/2021-03/msg00066.html
* lib/cdefs.h (__attribute_nonnull__): Rename from __nonnull.
All uses in Gnulib changed. There should be no need to change
glibc code that is not shared with Gnulib.
(__nonnull): New macro, defined in terms of __attribute_nonnull__,
and which can be used in glibc code that is not shared with Gnulib.

https://lists.gnu.org/r/bug-gnulib/2021-02/msg00064.html
* config/srclist.txt: Comment out dynarray_finalize.c.
* lib/dynarray.h (__libc_dynarray_at_failure): Don’t include
libc-config.h here, as that’s the includer’s responsibility.
* lib/malloc/dynarray_at_failure.c:
* lib/malloc/dynarray_emplace_enlarge.c:
* lib/malloc/dynarray_finalize.c:
* lib/malloc/dynarray_resize.c:
* lib/malloc/dynarray_resize_clear.c:
If _LIBC is not defined, include libc-config.h.
* config/srclist.txt: Mention the new files.
* lib/cdefs.h (__attribute_maybe_unused__): New macro,
like Gnulib’s _GL_ATTRIBUTE_MAYBE_UNUSED but with glibc
naming conventions.
* lib/libc-config.h: Use it instead of __glibc_likely.
* lib/dynarray.h, modules/dynarray: New files.
* lib/malloc/dynarray-skeleton.c, lib/malloc/dynarray.h:
* lib/malloc/dynarray_at_failure.c:
* lib/malloc/dynarray_emplace_enlarge.c:
* lib/malloc/dynarray_finalize.c, lib/malloc/dynarray_resize.c:
* lib/malloc/dynarray_resize_clear.c, modules/dynarray:
New files, from glibc with the following changes needed for
portability to compilers that are not recent-enough GCC.
* lib/malloc/dynarray_at_failure.c: Include stdlib.h, for abort.
(__libc_dynarray_at_failure) [!_LIBC]: Simply abort.
* lib/malloc/dynarray_emplace_enlarge.c:
* lib/malloc/dynarray_resize.c:
Include intprops.h, and use INT_MULTIPLY_WRAPV instead
of __builtin_mul_overflow.
* lib/malloc/dynarray.h (__libc_dynarray_at_failure):
Use _Noreturn instead of __attribute__ ((noreturn)).
* lib/malloc/dynarray_resize_clear.c: Do not include stdlib.h;
it’s not needed.
(__libc_dynarray_resize_clear): Do not do arithmetic on void *.
* lib/malloc/dynarray-skeleton.c (struct DYNARRAY_STRUCT):
Do not use anonymous unions, as they are not in C99. All uses changed.
Use __nonnull (X) instead of __attribute__ ((nonnull X)),
and __attribute_maybe_unused__ instead of __attribute__ ((unused)).
