26 -- TEST OBJECTIVE:
27 -- Check that an extended type can be derived from an abstract type,
28 -- where the abstract type is defined in a package, and the type derived
29 -- from it is defined in a distinct library package.
30 --
31 -- TEST DESCRIPTION:
32 -- Declare an private (abstract) type; declare two primitive operations
33 -- of the type that are explicitly abstract.
34 -- Derive an extended type from the (private) abstract type, overriding
35 -- both of the primitive operations.
36 -- This test also checks to see that name overloading between abstract
37 -- and non-abstract functions is resolved correctly.
