-- CHECK THAT DECLARED TASK OBJECTS ARE NOT ACTIVATED BEFORE
--   THE END OF THE DECLARATIVE PART.
-- SUBTESTS ARE:
--   (A)  A SIMPLE TASK OBJECT, IN A BLOCK.
--   (B)  AN ARRAY OF TASK OBJECT, IN A FUNCTION.
--   (C)  A RECORD OF TASK OBJECT, IN A PACKAGE SPECIFICATION.
--   (D)  A RECORD OF ARRAY OF TASK OBJECT, IN A PACKAGE BODY.
--   (E)  AN ARRAY OF RECORD OF TASK OBJECT, IN A TASK BODY.
 
-- THIS TEST ASSUMES THAT ACTIVATION IS A SEQUENTIAL STEP
--   IN THE FLOW OF CONTROL OF THE PARENT (AS IS REQUIRED BY THE
--   ADA RM).  IF AN IMPLEMENTATION (ILLEGALLY) ACTIVATES A
--   TASK IN PARALLEL WITH ITS PARENT, THIS TEST
--   IS NOT GUARANTEED TO DETECT THE VIOLATION, DUE TO A
--   RACE CONDITION.
 
-- JRK 9/23/81
-- SPS 11/1/82
-- SPS 11/21/82
-- R.WILLIAMS 10/8/86  ADDED CHECKS ON INITIALIZATIONS OF NON-TASK
--                     COMPONENTS OF RECORD TYPES.
-- PWN 11/30/94 REMOVED PRAGMA PRIORITY INSTANCES FOR ADA 9X.
