Someone involved with GNAT will certainly answer for that offering.

Rational has a DEC OSF/1 (Digital Unix) product as well.

DEC offers an Ada 83 compiler called DEC Ada which corresponds to their
VMS product by the same name.  I have never had a problem with lots of
generic instantiation on VMS, although my use is lots of simple generics
rather than more complex generics.  Following in their VMS tradition,
DEC OSF/1 has two debuggers.  One of them supports Ada, but I am not
experienced to say how good it is.

I would be surprised if the DEC product had image size problems on
DEC OSF/1, since the OS is aimed at 64 bit addressing, but you sound
like you had problems with some compiler in this environment so perhaps
it was DEC Ada.

Personally, I would be interested in seeing a mention of such problems
posted such that those of us who may want to depend on a particular
compiler in the future can be forwarned.
