First of all, note that I am aware of gcj's bytecode compilation modus
operandi, but with 'compiling with gcj' I generally intend to say
native compilation. Bytecode vs native compilation may be the reason
why it works in rhug and doesn't work for me.

Also I didn't try that hard to get Xalan running, so my statement may
have been a little rash. I have only tried to add xalan.jar to the gcj
command line, and to use Xalan bytecode via a ClassLoader from a gcj-
compiled executable, both of which failed.

But meanwhile I learned that gcj generally doesn't work well when fed
jars, and generally _does_ work well when fed only .java source codes.
This may be key. And maybe I can also learn something from the rhug
Makefiles.

Can you point me to more information on gcj's handling of sources,
classes and jars specified on the command line? The gcc docs are a
little sparse on Java-specific details.
