Furthermore, --march=i686 is included, which it definitely should not be given that I am on an athlon.

I'm more concerned with your CFLAGS... Try this: CFLAGS="-O2 -march=athlon -pipe" Then slowly raise until it breaks. jonner@teegra.net 2004-12-05 23:10:10 0000 I'm pretty sure Dirk's Athlon doesn't support SSE, though it does do MMX.
