This was fixed in gnulib by Paul Eggert:

2004-05-30  Paul Eggert  <address@hidden>

        * xmalloc.c (HAVE_MALLOC, HAVE_REALLOC): Do not require these
        macros to be defined.
        (xnmalloc_inline, xnrealloc_inline, xcalloc): Do not die if
        the allocator returns NULL because the requested size is zero.

You only need to use the new gnulib xmalloc.c instead of the one you found
in diffutils.
