Concerning the ahlon-xp- build, I guess (MMX+SSE+3DNOW required) means

CFLAGS="... -m3dnow -msse -mmmx"

or is it

CFLAGS="... -march=athlon-xp"

or is it (for nasm)

DHAVE_SSE DHAVE_MMX DHAVE_3DNOW

(as in the x264-Makefile, sorry, don't have one here now).

Maybe it is a bit of everything.
Most of these flags do not seem to make that much of a difference yet, the framerates seem to be not much higher or lower (on Linux again only).

I am just asking, because i want to build it on Linux, and therefor i am searching for Flags (C, nasm) where i can get optimal performance.

Maybe i test gcc-4.0-beta with x264.
