I checked out 7.0 using tag REL7_0_PATCHES, and I see this in configure.in:

AC_FUNC_MEMCMP

and this in configure:

echo "$ac_t""$ac_cv_func_memcmp_clean" 1>&6
test $ac_cv_func_memcmp_clean = no && LIBOBJS="$LIBOBJS memcmp.${ac_objext}"

However, I don't see any memcmp.c file, nor in 6.5 either. I wonder if
this was removed from configure.in because it was no longer being used.

The big question is whether we can backpatch in the memcmp code and have
it working cleanly in 7.2.
