* 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.
