gdb issues + how to upgrade gcj version for cross compilation

[Vladimir Leven <vladimirl at wrx-ca dot com>]

If I wish to upgrade to the latest version of GCJ, do I have to rebuild 
all of GCC, or only part of it? I have a cross compilation chain set up 
for my target platform. This chain uses GCC 3.2.3. Using GCJ 3.4.0 seems 
to solve with GDB, but to use it for the target platform, do I have to 
rebuild the entire gcc toolchain?
