I've seen optimization bugs in ifc also. '-O' works and '-O3' overwrites
the bounds of a memory section.

That would violate your Intel license I believe. But, remember that Athlon MP/XP
do in fact have SSE support. Not SSE2 however. If you were to use SSE instructions
from a non-Intel compiler, you would find the binaries do execute on the new
Athlons. (I have SSE ASM that I've run on them and it works just fine)
