-- OBJECTIVE:
--     FOR PREDEFINED TYPE INTEGER, CHECK THAT
--     CONSTRAINT_ERROR IS RAISED IF THE OPERAND VALUE OF A
--     CONVERSION LIES OUTSIDE OF THE RANGE OF THE TARGET TYPE'S BASE
--     TYPE. ALSO, CHECK THAT CONSTRAINT_ERROR IS RAISED IF THE
--     OPERAND VALUE LIES OUTSIDE OF THE RANGE OF THE TARGET TYPE'S
--     SUBTYPE BUT WITHIN THE RANGE OF THE BASE TYPE.
 
-- HISTORY:
--     RJW 09/08/86  CREATED ORIGINAL TEST.
--     RJW 11/13/87  ADDED CODE TO PREVENT DEAD VARIABLE OPTIMIZATION.
--     JET 12/30/87  ADDED MORE CODE TO PREVENT OPTIMIZATION.
--     MRM 03/30/93  REMOVED NUMERIC_ERROR FOR 9X COMPATIBILITY
--     JRL 12/08/96  Changed usages of System.Max_Int and System.Min_Int to
--                   Integer'Base'Last and Integer'Base'First in first two
--                   subtests.
