-- 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.
