--     CHECK THAT A SUBPROGRAM OR ENTRY CAN BE RENAMED WITH:
--       A) DIFFERENT PARAMETER VALUE;
--       B) DIFFERENT DEFAULT VALUES;
--       C) DIFFERENT PARAMETERS HAVING DEFAULT VALUES;
--     AND THAT THE NEW NAMES/DEFAULTS ARE USED WHEN THE NEW NAME IS
--     USED IN A CALL.
--     CASE WHERE THE AGGREGATE CONTEXT IN A RENAMING DECLARATION COMES
--     FROM THE SUBTYPE INDICATIONS IN THE RENAMED SUBPROGRAM,
--     ESPECIALLY FOR A DEFAULT EXPRESSION.

-- HISTORY:
--     RFB 04/06/84
--     EG  05/30/84
--     DWC 10/02/87  SPLIT OUT FUNCTION BODY C1 TO
--                   B85013D.ADA.
--     PWN 10/24/95  REMOVED CHECKS WHERE ADA 95 HAS REMOVED
--                   RESTRICTIONS.
--     PWN 03/28/96  Restored checks in Ada 95 legal format.
