Well, the gcc33 damage is already done. (Amazing what happens with emerge
when you're sleepy!) Anyway, it's benefited the group as that's the reason
we now have gentoo-sources-2.4.20-r7 which does build for me with gcc33.
(Those bugzilla guys are really great folks!)
So, since I do have gcc33, and vanilla-sources doesn't show the Athlon XP
option, I'll just enter an enhancement request. In the meantime I guess I
should just chose Athlon. It's running, although there are a lot of driver
things not working correctly yet, and I'm a bit nervous about fixing things
by using emerge.
QUESTION - If I'm running 2.4.22 and emerge -C alsa to fix it, does that
break Alsa when I boot back into 2.4.20? I hope not...
Cheers,
Mark
