Unfortunately, I have to link to ada libraries given to us by a
contractor
that are done using Sun Ada 2.1 as well.  Despite that our contract
requires
that we use commercially supported software.  To top that off, I
personally
have nothing to do with software installation, choices, et al, but have
been
informed by our person in that area that GNAT is not an option. (Which
he
also regrets and says that if we had the option we would have already
jumped
on it)

Simply put, is it at all possible with the resources I have now (Sun Ada
2.1
and Sun C++ 3.0, upgrading soon to Sun Ada 3.0, and Sun C++ 4.0) to link
Ada and C++?
