i have an athlon xp 2.5, any suggestions for cflags? i have this atm: CFLAGS="-O3 -march=athlon-xp -fforce-addr -fmerge-all-constants -ffast-math -fprefetch-loop-arrays -fstrict-aliasing -falign-functions=64 -falign-labels=1 -falign-loops=16 -falign-jumps=16 -mfpmath=sse -mpreferred-stack-bound here's a hint. if your IRC client lops off part of your CFLAGS, you have a problem
