gcj is a gcc front-end, and while it can compile to bytecode it's not
very good at it.  In Fedora we use ecj, Eclipse's compiler, to compile
to bytecode.  We use gcj (indirectly, via aot-compile-rpm) to compile
that bytecode into native code.

There are none.  Classpath's class library exists within libgcj's rpm.
