6ba3df05fe reallocarray: Fix compilation error in C++ mode (regr. 2024-11-04). 
* m4/reallocarray.m4 (gl_FUNC_REALLOCARRAY): Don't use
REPLACE_REALLOC_FOR_REALLOC_POSIX here. Use gl_cv_malloc_ptrdiff
instead.

d884e6fc4a realloc-posix: realloc (..., 0) now returns nonnull 
* lib/realloc.c (rpl_realloc): Simplify and tune by using
HAVE_REALLOC_0_NONNULL and HAVE_MALLOC_PTRDIFF, and
by having just one call to realloc instead of two.
* lib/reallocarray.c (reallocarray): Simplify and tune
by delegating the zero case to the revised realloc.
* m4/eealloc.m4 (_AC_FUNC_REALLOC_IF): Since only eealloc uses
this macro now, move its definition here ...
* m4/realloc.m4: ... from here.
(gl_FUNC_REALLOC_0_NONNULL): Also check that realloc (p, 0)
returns nonnull.  Require gl_FUNC_REALLOC_POSIX.
Define HAVE_REALLOC_0_NONNULL.
* m4/reallocarray.m4 (gl_FUNC_REALLOCARRAY):
Also replace reallocarray if it returns a null pointer for size zero.
* modules/eealloc (Files): Remove m4/realloc.m4.
* modules/realloc-posix (Depends-on): Add extensions-aix.
* modules/reallocarray (Files): Add m4/realloc.m4.

41a04c574d reallocarray: Fix compilation error in C++ mode on Android.
