-- OBJECTIVE:
--     CHECK THAT THE SIZE OF A DERIVED TYPE IS INHERITED FROM THE
--     PARENT IF THE SIZE OF THE PARENT WAS DETERMINED BY A SIZE
--     CLAUSE.

-- HISTORY:
--     JET  09/16/87 CREATED ORIGINAL TEST.
--     DHH  03/30/89 CHANGED SPECIFIED_SIZE TO 5, ADDED CHECK ON
--                   REPRESENTATION CLAUSES, AND CHANGED THE TEST
--                   EXTENSION FROM '.DEP' TO '.ADA'.
