-- 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).
