gcc.apple/default-x86_64-sse3.c has:
  #include <pmmintrin.h>
Clang's pmmintrin.h has:
  #include <emmintrin.h>
Clang's emmintrin.h has:
  #include <xmmintrin.h>
Clang's xmmintrin.h has:
  #include <mm_malloc.h>

gcc's mm_malloc.h has:
  #include <stdlib.h>

After r119343, Clang's mm_malloc.h has:
  #include <stddef.h>

The test case contains a (spurious) call to exit().  Cue clang warning about exit() not being declared and dejagnu complaining about extra "errors".

Not sure how best to resolve this one.  Maybe the test suite should suppress this warning like it does several others?  Maybe we should never change what's included by the builtin headers?  Anyway, not it.
