Gcc 3.0 do suport Athlon optimization. The Athlon XP core is from most points
of view same to Athlon's (instruction latencies, functional units, overall design),
so the settings should work well. It is enabled by -march=athlon
Development versions of GCC 3.1 have support for SSE float arithmetic that can
speed up considerably single precision floating operations. (enabled by -msse)
