-- OBJECTIVE:
--     CHECK THAT A DECLARATION IN A DECLARATIVE REGION FOR A GENERIC
--     PACKAGE HIDES AN OUTER DECLARATION OF A HOMOGRAPH. ALSO CHECK
--     THAT THE OUTER DECLARATION IS DIRECTLY VISIBLE IN BOTH
--     DECLARATIVE REGIONS BEFORE THE DECLARATION OF THE INNER HOMOGRAPH
--     AND THE OUTER DECLARATION IS VISIBLE BY SELECTION AFTER THE INNER
--     HOMOGRAH DECLARATION.

-- HISTORY:
--     BCB 08/30/88  CREATED ORIGINAL TEST.
