--     CHECK THAT IF A SIZE SPECIFICATION INDICATING THE SMALLEST SIZE
--     APPROPRIATE FOR A SIGNED REPRESENTATION IS GIVEN FOR AN
--     ENUMERATION TYPE, THEN OPERATIONS ON VALUES OF SUCH A TYPE
--     ARE NOT AFFECTED BY THE REPRESENTATION CLAUSE.
 
-- HISTORY:
--     RJW 07/28/87 CREATED ORIGINAL TEST.
--     PWB 05/11/89 CHANGED EXTENSION FROM '.DEP' TO '.ADA'.
--     JRL 03/27/92 ELIMINATED REDUNDANT TESTING.
