Bruno Haible <bruno@clisp.org>
Make the module 'realloc-gnu' work again on AIX and OSF/1.
* m4/realloc.m4 (gl_FUNC_REALLOC_GNU): Define HAVE_REALLOC_GNU instead
of HAVE_REALLOC.
* lib/realloc.c (NEED_REALLOC_GNU): Enable behaviour also when
GNULIB_REALLOC_GNU && !HAVE_REALLOC_GNU.
(SYSTEM_MALLOC_GLIBC_COMPATIBLE): Adjust definition.
* modules/realloc-gnu (configure.ac): Use gl_MODULE_INDICATOR.
