Yes, this is a total swamp. I suggest you read this:

  http://autopackage.org/docs/devguide/ch07.html

It's a little out of date, doesn't cover all the issues, is inaccurate in
places etc but AFAIK it's the only documentation on this stuff that exists.

The issue is likely to be not so much gcc4 as glibc, though gcc can cause
occasional issues as well. If you only want to go back one revision of
Fedora though you should not encounter any of them.

You can use the apbuild tool to automatically fix many of these problems.
