-- OBJECTIVE
-- Check the requirements of 10.1.5(4) and the modified 10.1.5(5)
-- from Technical Corrigendum 1. (Originally discussed as AI95-00136.)
-- Specifically:
-- Check that program unit pragma for a generic package are accepted
-- when given at the beginning of the package specification.
-- Check that a program unit pragma can be given for a generic
-- instantiation by placing the pragma immediately after the instantation.
--
-- TEST DESCRIPTION
-- This test checks the cases that are *not* forbidden by the RM,
-- and makes sure such legal cases actually work.
--
-- CHANGE HISTORY:
-- 29 JUN 1999 RAD Initial Version
-- 08 JUL 1999 RLB Cleaned up and added to test suite.
-- 27 AUG 1999 RLB Repaired errors introduced by me.
