I had problems with the java part of java.lang and
gnu.java.awt.peer.gtk, and the awt part of java.awt and
gnu.java.awt.peer.gtk.  Using gnu.javaz.awtz.peer.gtk got me past the
namespace or class unknown error.  CLASSPATH came up with
gnu.java.awt.peer.gtk, so I'm stickly with it until I can get the
conversion to cni completed, then I'll think about shortening the
package name to something like Per suggested.

I'm hoping so, because I'm reasonably certain that it is a common
practice to have duplicate package names with different parent
packages in Java.

I'm learning namespaces for the first time, too.  Is there a good
reference on the internet for learning about namespaces?

I'm going to start by looking through the gcc source code.  I'll post
whatever I discover.
