-- OBJECTIVE:
--     CHECK THAT CONSTRAINT_ERROR IS RAISED WHEN THE SUBTYPE
--     INDICATION IN A CONSTANT OBJECT DECLARATION SPECIFIES A
--     CONSTRAINED SUBTYPE WITH DISCRIMINANTS AND THE INITIALIZATION
--     VALUE DOES NOT BELONG TO THE SUBTYPE (I. E., THE DISCRIMINANT
--     VALUE DOES NOT MATCH THOSE SPECIFIED BY THE CONSTRAINT).
 
-- HISTORY:
--     RJW 08/25/86  CREATED ORIGINAL TEST
--     VCL 08/19/87  CHANGED THE RETURN TYPE OF FUNTION 'INIT' IN
--                   PACKAGE 'PRIV2' SO THAT 'INIT' IS UNCONSTRAINED,
--                   THUS NOT RAISING A CONSTRAINT ERROR ON RETURN FROM
--                   'INIT'.
