  25 -- OBJECTIVE:
  26 --     FOR PREDEFINED TYPE INTEGER, CHECK THAT
  27 --     CONSTRAINT_ERROR IS RAISED IF THE OPERAND VALUE OF A
  28 --     CONVERSION LIES OUTSIDE OF THE RANGE OF THE TARGET TYPE'S BASE
  29 --     TYPE. ALSO, CHECK THAT CONSTRAINT_ERROR IS RAISED IF THE
  30 --     OPERAND VALUE LIES OUTSIDE OF THE RANGE OF THE TARGET TYPE'S
  31 --     SUBTYPE BUT WITHIN THE RANGE OF THE BASE TYPE.
  32
  33 -- HISTORY:
  34 --     RJW 09/08/86  CREATED ORIGINAL TEST.
  35 --     RJW 11/13/87  ADDED CODE TO PREVENT DEAD VARIABLE OPTIMIZATION.
  36 --     JET 12/30/87  ADDED MORE CODE TO PREVENT OPTIMIZATION.
  37 --     MRM 03/30/93  REMOVED NUMERIC_ERROR FOR 9X COMPATIBILITY
  38 --     JRL 12/08/96  Changed usages of System.Max_Int and System.Min_Int to
  39 --                   Integer'Base'Last and Integer'Base'First in first two
  40 --                   subtests.
