And neither me... Maybe it's not necessary to work hard on this: Apple prefers Clang and LLVM GCC 4.2 over GCC 4.5, 4.6, 4.7,... These produce files unexmacosx can handle.
Here is a slightly different failure when I use GCC 4.7.0:

To most people solutions mean finding the answers. But to chemists solutions
are things that are still all mixed up.
