Multiple GCC versions

Hi, just a couple of questions:

1. Is it cool to have multiple gcc versions (that come from RPM
packages), by doing the usual rpm -ivh <foo>? 

Rawhide has gcc32 and gcc4, but I'd like to have gcc 2.95, and gcc 3.3
to be honest (3.3, mainly for some qemu stuff)

2. Where do I get rpms for these? Can I just use old gcc3.3 rpms from
FC-2? I tried to rebuild it out of cvs (dist-fc2) and gcc3.3 didn't
build with gcc4 ;-)

Any ideas would be appreciated, thanks
