Thanks!  This is great!

I think we should check this in on the trunk as soon as the gcc 3.0
branch is made.  Hans, I've forgotten -- have you filed paperwork with
the FSF?

This is fairly easy to fix.  We can simply put -fhash-synchronization
into libgcj.spec.

I think what I'd like to do here is install a system-specific include
file called `gcjconfig.h'.  We'd have configure create this.  We'll
install it in some system-specific directory that is automatically
searched by g++.  Then we can simply have Object.h include this file.
