-- OBJECTIVE:
--     CHECK THAT A DERIVED TYPE DECLARATION IN A GENERIC
--     UNIT MAY DERIVE TWO OR MORE SUBPROGRAM HOMOGRAPHS.
--     CHECK THE CASES WHERE:
--          1) THE DERIVED SUBPROGRAMS BECOME HOMOGRAPHS BECAUSE OF THE
--             SUBSTITUTION OF THE DERIVED TYPE FOR THE PARENT TYPE IN
--             THE IMPLICIT SUBPROGRAM SPECIFICATIONS.
--          2) THE PARENT TYPE IS DECLARED IN A GENERIC INSTANCE AND
--             THE INSTANCE INCLUDES TWO OR MORE DERIVABLE SUBPROGRAMS
--             THAT ARE HOMOGRAPHS AS A RESULT OF THE ARGUMENTS GIVEN
--             FOR THE GENERIC FORMAL-TYPE PARAMETERS.
--     TEST CASES WHERE THE DERIVED TYPE DECLARATIONS ARE GIVEN IN:
--          . THE VISIBLE PART OF A GENERIC PACKAGE SPECIFICATION,
--          . THE PRIVATE PART OF A GENERIC PACKAGE SPECIFICATION,
--          . A GENERIC PACKAGE BODY,
--          . A GENERIC SUBPROGRAM BODY.
