Can you add a suitable main() to the test case to make it executable?  I'd like
to check it on two strict-alignment platforms (ARMv5 and SPARC).  A cursory
inspection of the generated assembly code hints that gcc-4.6-20110923 and
gcc-4.7-20110924 keep the memcpy() calls when targeting armv5tel-linux-gnueabi.
