Is there anything that is conditional when compiling GCC that maybe the Gentoo crossdev folks have changed over time, which could mask this behaviour? I don't imagine they were patching those headers. However, when I rebuild my cross GCC 4.7.3 with crossdev, it now fails, as you've noted. I am happy to test patchsets, and or even come up with them if you think this is something worth delegating. I have no experience in GCC's tree, but I can follow orders :)
