--*

-- 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.
