Apologies for replying to my own post, but I made a silly oversight:

Oops, kinda bleemed over this line.

Hmm. Maybe instead you should get your manager or system administrator
to call SGI and have a word with them ... :-)

You can e-mail stebbins@engr.sgi.com (Michael Stebbins) to request a beta
tester license for gnat 3.05

I did talk to SGI, eventually (1 week for response).
By that time I found a work-around.
Problem encountered with a for use at.
Code notionally was:
X : float := 0;
for X use at memory_manager.next_address( X'size, "SUBSYSTEM.X" );
We use memory_manager to map things to ScramNet.
Gnat insisted that the at value had to be a prior define constant.
So changed the code to:
X_ADDRESS : constant system.address :=
memory_manager.next_address( X'size, "SUBSYSTEM.X" );
X : float := 0;
for X use at X_ADDRESS;
This worked until in one unit I reversed the order of the first two
lines of code.
X : float := 0;
X_ADDRESS : constant system.address :=
memory_manager.next_address( X'size, "SUBSYSTEM.X" );
for X use at X_ADDRESS;
Found what the problem was when attempted to make this change in a spec
where gnat still insisted that the at value had to be a prior defined
constant.
In a body, got the Gigi abort 116 instead. Unsure whether it was
the fact that it was in the body, or whether the new declaritive
block inside the body had anything to do with the error.
But reversing the first two lines of code got rid of the abort code.
Hope this helps someone else.

Yes, after my first post, I noticed that I'd missed the fact that you'd
already put in a call to them, but that they were slow to respond. A
whole week? Wow, not a good sign. A few months ago, working a project
that used SGI's compiler, I recall that we got pretty good response from
them. Then again, a week is really not all that bad, if you compare it
to the geological slowness of some Ada vendors (who shall remain
nameless) during the 1980's. :-)
Giving SGI the benefit of the doubt, maybe the 1-800 number isn't the
best avenue for getting quick help from them. You might want to look
into becoming a beta site for SGI (or get your higher-ups to look into
it). That way, you can get interim updates of the compiler and talk
with SGI's engineers directly. Anyway, a little bird tells me that SGI
may be coming out with an official update of their GNAT port fairly
soon. I defer to any SGI folks who might want to chime in at this point
