-- CHECK THAT WHEN A VARIABLE OR CONSTANT HAVING AN ENUMERATION,
--    INTEGER, FLOAT OR FIXED TYPE IS DECLARED WITH AN INITIAL VALUE,
--    CONSTRAINT_ERROR IS RAISED IF THE INITIAL VALUE LIES OUTSIDE THE
--    RANGE OF THE SUBTYPE.

-- HISTORY:
--    RJW 07/20/86  CREATED ORIGINAL TEST.
--    JET 08/04/87  IMPROVED DEFEAT OF COMPILER OPTIMIZATION.
