-- OBJECTIVE:
--     CHECK THAT A SIZE SPECIFICATION FOR AN INTEGER TYPE OF THE
--     SMALLEST APPROPRIATE SIGNED SIZE CAN BE GIVEN:
--        IN THE VISIBLE OR PRIVATE PART OF A PACKAGE FOR A TYPE
--          DECLARED IN THE VISIBLE PART;
--        FOR A DERIVED INTEGER TYPE;
--        FOR A DERIVED PRIVATE TYPE WHOSE FULL DECLARATION IS AS
--          AN INTEGER TYPE;
--        FOR AN INTEGER TYPE IN A GENERIC UNIT.

-- HISTORY:
--     JET 08/12/87  CREATED ORIGINAL TEST.
--     DHH 04/11/89  CHANGED EXTENSION FROM '.DEP' TO '.ADA', CHANGED
--                   SIZE CLAUSE VALUE TO 7, CHANGED OPERATOR ON 'SIZE
--                   CHECKS, ADDED REPRESENTAION CLAUSE CHECK, AND
--                   ADDED CHECK ON INTEGER IN A GENERIC UNIT.
--     BCB 10/03/90  CHANGED FAILED MESSAGES FROM "SHOULD NOT BE GREATER
--                   THAN" TO "MUST BE EQUAL TO".
--     JRL 03/27/92  REMOVED TESTING OF NONOBJECTIVE TYPES.
