GNAT has -gnat83 as well, but rejects, too, because there are
neither tagged nor abstract types in Ada 83.

Just out of curiosity, given

   type T is tagged ...;
   type D is new T with ...;
   type E is new D with ...;

what would E'Base be?

Assuming that D is privately tagged, would E'Base
have different effects depending on whether E's tag
is visible or not?
