[Bug-gnulib] How do malloc.c and realloc.c get used?

[Gary V . Vaughan]

Hi,

I'm in the process of porting my adhoc portability files for GNU m4 
over to gnulib,
but while adding the xalloc module I noticed something odd: Despite the 
fact the modules/xalloc file declares reliance on both malloc.c and 
realloc.c, there doesn't appear to be anyway rpl_malloc or rpl_realloc 
can be called.

My guess is something like the following is missing?

malloc.m4 (jm_FUNC_MALLOC):
  if test X"$ac_cv_func_malloc_0_nonnull" = Xno || test 
X"$ac_cv_func_malloc_wo\
rks" = Xno; then
    gl_PREREQ_MALLOC
    AC_DEFINE(NEED_RPL_MALLOC, 1,
        [Define to 1 if system malloc cant handle 0 sized mallocations])
  fi

xalloc.h:
  #if NEED_RPL_MALLOC
  #  define malloc rpl_malloc
  #endif

Or am I missing something?

Cheers,
        Gary.
