Ok, fair question.  I checked sources.redhat.com's usual repository
and didn't find anything else (assuming "gcc" covers its entire
repository).

However, I'd like to think about this for a bit, and come up with a
migration plan, rather than just letting people randomly migrate files
they're interested in.
