[Numpy-discussion] Python and Numpy compiled on Athlon optimized gcc3.01

Just for kicks last night I installed gcc3.01 which claims to have
Athlon optimization, ie. -march=athlon.  I recompiled Python and Numpy,
and then ran a big simulation.  The new compiler ran 200 seconds slower
than the old gcc2.95 with plain -march=pentium.  I need to go to the gcc
website and see just what optimization they are claiming.  Maybe I
should have also used -02.      Rob.
