This change bootstraps fine with current gcc trunk on x86_64-apple-darwin11. It
almost fixes the failures in the boehm-gc test suite. The -m32 results always
pass as...

        === boehm-gc Summary for unix/-m32 ===

# of expected passes        12
# of unsupported tests        1

but often the -m64 results show the failure...

Are there any other darwin related changes upstream?
