*Well*, if you find any package that is not current RPMed, you can make an
RPM as you install it and then post to for all
of us to use.

All of these are at

You may have to rebuild from source (rpm --rebuild blah.srpm), because
some might be compiled for redhat 4.x. Not that you don't have to install
packages that aren't currently installed (loadlin, especially, and unless
you use NFS you can probably avoid that), and pcmcia-cs is best rebuilt
from the latest sources at

Yes. All these packages are backward-compatible.

Yes. 'man lilo'.

gcc is going back into active development by (at least) three different
groups, who make efforts to keep most of their codebases synchronized, but
have different goals. <wandering into dangerous territory> Most people
should stick with gcc for the moment. <running back out>

[Note to linux-kernel: before you comment on the above statement, consider
the context of the original question. I *do know* all the various reasons
for gcc/pgcc/egcs/etc and what they're working on and what they do, but
gcc is undoubtedly best for Mr. McGillick at the moment.]
