Now the others flag  mmx, mmx2, 3dnow, 3dnow2, etc you must be setting 
on USE clausule.

        I'm using "-O3 -march=pentium2 -mmmx -ffast-math -fomit-frame-pointer -pipe" 
as CFLAGS
(and CXXFLAGS), and I wonder if -mmmx may be omited. The actual question is, does
-march=xxx includes mmx, mmx2, 3dnow, 3dnow2, sse and sse2 for appropriate arch? And 
what
to use as CFLAGS for my Celeron 300A (Mendocino)? Thanx a lot. :o)
