Just for the record (if someone needs this info in a few months...):

Let's test it. ;-)

I'm currently using "-Os -march=athlon-xp -mfpmath=sse
- -fomit-frame-pointer -pipe" on my not-up-to-date system with gcc-3.2.3,
after reading a bit of the gcc source. -mmmx and -msse are enabled
implicitly for athlon-xp, IIRC, so I had dropped them from my old
CFLAGS some months ago.
