Thanks!  Any complaints / suggestions on the interface (I'm not that 
happy with it).

We[gdb community] only have all the others.

I remember you asking the question, but when I went back I couldn't 
re-find it :-(

Language lookup_primative_type_by_name struck be as just wrong.  I even 
tried to eliminate it but stumbled into a minefield (something to do 
with how C & C++ are a hybrid, the details elude me).

My hunch is that Ada, and the other languages, should instead have 
per-osabi local data (see reggroups for how to do this without needing 
changes to the architecture vector) that contains the language specific 
primitive types that they really need.

With this in place, and having looked through the code, I think we've just:

-- strip out the #ifdef GNAT_GDB code
(I'll send you a better way to maintain local changes off-list)

-- enable Ada

left.
