-- OBJECTIVE:
--     CHECK THAT CONSTRAINT_ERROR IS RAISED BY PUT FOR ENUMERATION
--     TYPES WHEN THE VALUE OF WIDTH IS NEGATIVE, WHEN WIDTH IS
--     GREATER THAN FIELD'LAST, OR WHEN THE VALUE OF ITEM IS OUTSIDE
--     THE RANGE OF THE SUBTYPE USED TO INSTANTIATE ENUMERATION_IO.

-- HISTORY:
--     SPS 10/08/82
--     DWC 09/17/87  ADDED CASES FOR CONSTRAINT_ERROR.
--     JRL 06/07/96  Added call to Ident_Int in expressions involving
--                   Field'Last, to make the expressions non-static and
--                   prevent compile-time rejection.
