WRONG!!! Please RTFM before making remarks like these.
As I've said earlier, GCC is actually a code-generating backend, which
calls the appropriate compiler to compile different languages. So, it calls
CC1.EXE for C compilations, and GNAT1.EXE for Ada compilations. There is no
intermediate C code, except for a very small (mostly < 20 lines) piece
of code which ensures that the linker will get some things right in glueing
all you Ada object code together. In the future this information might also
go in the .o files. As for the name, the AT of GNAT stands for Ada
Translator indeed, but that's essentially what a compiler is: a translator
from one language to another, for example from C to 370 assembly, or from
Ada to 80386 assembly.

Are you sure you have the latest release (v2.05)? Since the GNAT project
hasn't finished yet and especially tasking, real-time constructs and
distributed computing constructs (automatically generating/using RPC
interfaces, for example) are still under construction.

The completion of the implementation of the full Ada-95 language, including
all annexes concerning real-time systems, systems programming and
distributed computing for example, is scheduled for this summer. In March
the project was still on schedule (rather unique for a project this large),
and when looking at the rate at which the unimplemented features got
implemented, I'm confident Ada-95 will be out before Win-95 ;-) Which is
not too hard a goal, of course.

So, if you have an old version (even a .01 version difference), the newest
(2.05) version might provide everything you need. If anything you need
isn't there yet, please wait or ask about it in comp.lang.ada, or send mail
to gnat-request{at}cs.nyu.edu.
