-- OBJECTIVE:
--     CHECK THAT CONSTRAINT_ERROR IS RAISED BY PREDEFINED
--     LONG_INTEGER "**" IF THE SECOND OPERAND HAS A NEGATIVE
--     VALUE.

-- APPLICABILITY CRITERIA:
--     IN ORDER FOR THIS TEST TO BE NOT-APPLICABLE THE COMPILER
--     MUST REJECT THE USE OF "LONG_INTEGER" AS AN UNDECLARED
--     IDENTIFIER.

-- HISTORY:
--     HT  10/07/86  CREATED ORIGINAL TEST.
--     JET 08/06/87  REMOVED BUG FROM FUNCTION IDENT (X).
