I'm not competent enough to answer this. Anything tightly integrated with

I think it also chooses some in

Correct. Of course, there's the experimental pgcc (http://www.goof.com/,
if anybody wants to look).
I'd like to pack this up and stuff it into experimental, if I had a

If I remember right, configuring for pentium leaves an executable
that might not run on 386 or
