There's some regression in the latest gcc-3.3 snapshot concerning
mmx (or so I gather from a discussion on the list that's way over my
head). I can't build a working "mplayer" anymore with "-march=k6-2".
It was working a few weeks ago. No such problems (on
NetBSD-1.6.1/i386) with gcc-3.2.2, and I'm even running a kernel built
with COPTS="-O2 march=k6-2" (and DEFWARNINGS="no") by gcc-3_3-branch
from a couple weeks ago. Besides that, the most noticable thing about
the gcc3 compilers is that they take longer to compile anything.
