Oops. This is what I meant to say - what I get when I divide my attention. Pity, since I just recently installed a Gentoo system for the same processor. > '-athlon64' is not a valid CFLAG, also -sse/2 and -3dnow are all implied > by -march=athlon64 and I'm quite sure that -mfpmath=sse is also the default > on amd64.
