That was actually easy:

 if FOUND_GCJ
 JAVAC = $(GCJ) -C -d . @classes

So the actual jikes command that is run from lib during the build is:

/usr/bin/jikes +F -bootclasspath '' -extdirs '' -sourcepath ''
-classpath ..:../vm/current:.: -d . @classes

If I followed the gcj mailinglist correctly then the next version of gcj
will also know about these flags. And I believe the latest kjc also
handles them so we might want to do this for all compilers in the
future.

(Note to Debian loving people: Jikes Version 1.15b(CVS) - 9 Feb 2002
just entered unstable!)

I also added the following stub to Socket.java so java.util.logging can
actually compile:

And this small reversal of a Class.java change that made it impossible
to use it with Orp 1.0.9.
