We had a brief talk about this yesterday, but this time difference is a
problem, so we should probably revert to mail;)

The fact that gcj will keep duplicates of many of the gcc headers,
libraries and programs, is indeed an ugly technical problem. One thing
is that it eats disk space.

Another is the libraries now required by gcj-compiled packages. Will
they have rpaths pointing to /opt in them? If not, how do we know they
work with whatever version of gcc is in /usr? If they do indeed point to
/opt, and somebody uninstalls (or upgrades gcj to an ABI-incompatible
version), all gcj-compiled apps could break, right?
