Torbjörn,
    I see the same problem without the patch. The stock Apple gcc 4.0.1
compiler doesn't understand the -mtune=core2 option so it ends up using
-mtune=k8. The Apple gcc-4.2.1 compiler does and configure ends up using
-mtune=core2. However both builds yield the same set of testsuite failures
(none of which exist in gmp 4.2.1). Do you have access to a Intel based
Mac to test gmp 4.3.0 directly?
