-- OBJECTIVE:
--     CHECK THAT A TASK THAT IS DECLARED IN A NON-LIBRARY PACKAGE
--     (SPECIFICATION OR BODY) DOES NOT "DEPEND" ON THE PACKAGE,
--     BUT ON THE INNERMOST ENCLOSING BLOCK, SUBPROGRAM BODY,
--     OR TASK BODY.
--     SUBTESTS ARE:
--       (A)  A SIMPLE TASK OBJECT, IN A VISIBLE PART, IN A BLOCK.
--       (B)  AN ARRAY OF TASK OBJECT, IN A PRIVATE PART, IN A FUNCTION.
--       (C)  AN ARRAY OF RECORD OF TASK OBJECT, IN A PACKAGE BODY,
--            IN A TASK BODY.
 
-- HISTORY:
--     JRK 10/13/81
--     SPS 11/21/82
--     DHH 09/07/88 REVISED HEADER, ADDED EXCEPTION HANDLERS ON OUTER
--                  BLOCKS, AND ADDED CASE TO INSURE THAT LEAVING A
--                  PACKAGE VIA AN EXCEPTION WOULD NOT ABORT TASKS.
--     PWN 01/31/95 REMOVED PRAGMA PRIORITY FOR ADA 9X.
