Hello Everyone,

I've just been playing with the -march flags and found a huge speed increase
when I used -march=pentuim.  If this works so good, why is there a push for a
pentium optimized gcc?	Doesn't -march=pentium make pentium optimized code? 
It does seem to speed things up alot.  I had tried PGCC and was a little
disappointed with the speed increases so I stayed with regular Djgpp.  Now it
seems that I had a pentium optimizing compiler all along.  I'm confused...

Does anyone know of any gotcha's with using -march=pentium flags?

Thanks,

Doug Eleveld
