Well, I was thinking more of site-specific custom cuts a la this sort
of thing:

(which you wouldn't, probably, want to submit back upstream:-) but yes...

Multiarch isn't that bad -- it requires maintaining twinned repos for
the different archs, and I'm sure both rpm and fedora distros do this
pretty much transparently for i386 and x86_64 and less so (for no
terribly good reason but fewer users) for any of the other archs out
there.  But multiple compilers -- wow.  Never really thought of that
one.

Maybe I should ask an actual question on the yum list (which, after all,
I endure listening to on a daily basis) and see if there are any
suggestions for compiler management.  What do you do, install particular
compilers per system and then need packages to match, or install all the
per-compiler packages on all systems and select the one you link to some
other way?
