memcasecmp change imported from gnulib

[Paul Eggert]

I installed this into coreutils.  Somehow I missed it in my previous
pass comparing gnulib to coreutils.

2005-03-21  Paul Eggert  <address@hidden>

        Another change imported from gnulib.
        * memcasecmp.m4 (gl_MEMCASECMP): Renamed from gl_FUNC_MEMCASECMP.
        All uses changed.  Require AC_HEADER_STDC instead of invoking it.
        Remove check for stddef.h, size_t, const, since we now assume
        C89 or better.
