Sorry, my apologies.

I did that. The latest was with gcc-3.0.1 CVS and it is slower. Gcc-3.1.x should deliver some speedup (catch up) but I haven't tested it, yet. Especially -mcpu=k6 and only -O (nothing) is needed. -mpreferred-stack-boundary=2 is second one. <flamewar mode> Wouldn't IBM sell some Athlon MP systems?
