It doesn't realy fit with gcc's way of doing things.
For one thing, it would be inconsistent with compiling from
source if the source file defines multiple classes.  Basically,
each invocation of cc1java (the actual compiler) can only generate
a single .o file.

Why not just:

gcj -o baz.exe --main=org.foo.bar.Baz */*/*/*.class

or:

gcj -c -d . */*/*/*.class -o Baz.o
gcj -o baz.exe --main=org.foo.bar.Baz Baz.o

Faster compilation time; simple Makefile.
