-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained

-- this public release, the Government intends to confer upon all
-- recipients unlimited rights equal to those held by the Government.
-- These rights include rights to use, duplicate, release or disclose the

-- DISCLAIMER

--
-- TEST OBJECTIVE:
-- Check that an extended type can be derived from an abstract type,
-- where the abstract type is defined in a package, and the type derived
-- from it is defined in a distinct library package.
--
-- TEST DESCRIPTION:
-- Declare an private (abstract) type; declare two primitive operations
-- of the type that are explicitly abstract.
-- Derive an extended type from the (private) abstract type, overriding
-- both of the primitive operations.
-- This test also checks to see that name overloading between abstract
-- and non-abstract functions is resolved correctly.
