 I was able to build again the java bits (compiler and RT) today on a
 RHS box.

 Wierd. I don't see that happening. Here's what I get:

 OK. I have two questions:
 
   - Can you do a `p ((tree)0x82aeb4c)->common.type' and a 
     `p debug_tree (0x82b1268)' and send me the result?
   - Is it an up-to-date java/ source tree that you patched?

 Absolutely. I was going to post a revised patch. Sorry.
