I'd prefer sticking to gcc-4.1

So, this person has a pentium m, and /proc/cpu info says his processor belongs to family 6... as you can see, mine also belongs to family 6... so even though the wiki stages march=prescott, what do you guys think?

-march=pentium-m prefers x87 over sse scalar code, because pentium-m can decode sse at only half the rate of x87. You should see the speed advantage clearly on pentium-m, presumably not on Core Duo.
