This approach sounds good to me. For libgcj, we'd have something like:

libgcj.so.2 -> libgcj-3.0.0.so

Where the interface number (starting at "2" to differentiate from the redhat
release) gets bumped for each major release when incompatible ABI changes are
made, and the "3.0.0" tracks the actual package version.

Incidentally libstdc++ doesn't seem to be doing this kind of thing any more:

libstdc++.so -> libstdc++.so.3.0.0

I guess thats because they're confident in not making any more incompatible
changes?
