-- OBJECTIVE:

--     CHECK THAT CONSTRAINT_ERROR IS RAISED BY

--     "+" AND "-" FOR PREDEFINED LONG_INTEGER WHEN THE RESULT IS

--     OUTSIDE THE RANGE OF THE BASE TYPE.

-- APPLICABILITY CRITERIA:

--     THIS TEST IS APPLICABLE IF THE IMPLEMENTATION HAS A

--     PREDEFINED TYPE LONG_INTEGER.

--     IF LONG_INTEGER IS NOT SUPPORTED, THEN THE DECLARATION OF

--     "TEST_VAR" MUST BE REJECTED.

-- *** NOTE: This test has been modified since ACVC version 1.11 to    -- 9X

-- ***       remove incompatibilities associated with the transition   -- 9X

-- ***       to Ada 9X.                                                -- 9X

-- HISTORY:

--     TBN 10/07/86  CREATED ORIGINAL TEST.

--     JET 12/30/87  ADDED CODE TO PREVENT OPTIMIZATION.

--     JRL 03/30/93 REMOVED NUMERIC_ERROR FROM TEST.
