I'm planing this. Some work is done locally already. Will submit 
patches part by part.

I tried compiling classpath with
  jikes 1.18,
  gcj trunk,
  gcj 3.2.3 20030221 (Debian prerelease).

With jikes and trunk all is okay. With 3.2.3 I got the following 
error:

/usr/bin/gcj-3.2 --bootclasspath '' -classpath 
/home/mkoch/src/classpath-work:/home/mkoch/src/classpath-work/external/jaxp/source:../vm/current:.: 
- -C -d . @classes
/home/mkoch/src/classpath-work/java/awt/font/TextAttribute.java:43: 
Superclass `AttributedCharacterIterator.Attribute' of class 
`java.awt.font.TextAttribute' not found.
   public final class TextAttribute extends 
AttributedCharacterIterator.Attribute

At least this means the bug is fixed in trunk. I couldnt test with 3.3 
branch.

I hope this helps a little bit.
