--     OR PRIVATE PART OF A PACKAGE FOR A RECORD TYPE DECLARED IN
--     THE VISIBLE PART OF THE SAME PACKAGE.

-- HISTORY:
--     PWB 03/25/89  MODIFIED METHOD OF CHECKING OBJECT SIZE AGAINST
--                   TYPE SIZE; CHANGED EXTENSION FROM '.ADA' TO '.DEP'.
--     VCL  10/07/87  CREATED ORIGINAL TEST.
