": Should a validated Ada95 compiler flag this usage?  I realize that GNAT
: is not validated."

You realize wrong! GNAT was the first general purpose Ada 95 compiler
to be validated. We validated on the floor at Tri-Ada 96, and are now
the proud owners of ACVC 2.0 validation certificates numbers 2, 3 and
4. These validations were for SGI machines, but we expect many othr
GNAT validations in the future.

Of course validation does not ensure 100% compliance, so it is by no
means amazing to find a bug, but in fact this particular bug is
certainly fixed now (I don't know when exactly it was fixed), and
we now get a nice error message.
