It could be done with a chain of OpenJDK versions going back to
OpenJDK 6. Each release can build the previous one. You'd also
need a chain of old GCC releases, because old OpenJDK wasn't
necessarily compilable with a modern GCC.
But bear in mind that even GCJ needed precompiled binaries: the
class library could be recompiled from source, but it needed a
binary class library. So I'm not convinced that it's much of an
advantage to use GCJ, really.
Andrew.
