Assuming that you have a copyright assignment for GCC, please send the 
gcj patches to java-patches@gcc.gnu.org.  I am going to work on GCJ next.

Currently gcj works well enough that a simple Hello world program works 
on n32.  There is a problem in boehm-gc that prevents n64 from working.  
Finding and fixing that will be my next project.
