-- OBJECTIVE:
--     CHECK THAT WHEN A VARIABLE OR CONSTANT HAVING A CONSTRAINED TYPE
--     WITH DISCRIMINANTS IS DECLARED WITH AN INITIAL VALUE,
--     CONSTRAINT_ERROR IS RAISED IF THE CORRESPONDING DISCRIMINANTS OF
--     THE INITIAL VALUE AND THE SUBTYPE DO NOT HAVE THE SAME VALUE.

-- HISTORY:
--     RJW 07/20/86
--     DWC 06/22/87  ADDED SUBTYPE PRIVAS.  ADDED CODE TO PREVENT DEAD
--                   VARIABLE OPTIMIZATION.
