26-- OBJECTIVE:
27--      Check that a type derived in a client of a public child inherits
28--      primitive operations from parent.
29--
30-- TEST DESCRIPTION:
31--      Declare a root record type with discriminant in a package
32--      specification. Declare a primitive subprogram for the type
33--      (foundation code).
34--
35--      Add a public child to the above package.  Derive a new type
36--      with constraint to the discriminant record type from the parent
37--      package.  Declare a new primitive subprogram to write to the child
38--      derived type.
39--
40--      In the main program, "with" the child.  Derive a new type using the
41--      record type from the child package.  Access the inherited operations
42--      from both parent and child packages.
43--
44-- TEST FILES:
45--      This test depends on the following foundation code:
