Let me add, that anyone that wants to do multi-translation unit work 
should check out the compile server.  In it, we have all units in the 
symbol table simultaneously for C++, so if one wanted, they can do all 
sorts of things export, ODR checking, linting...  I plan on unification 
of IMA (IMI) with that code.

I'd be happy to entertain questions if people are interested.
