--
-- OBJECTIVE:
-- Check that the specifications of the package Interfaces.C.Pointers
-- are available for use.
--
-- TEST DESCRIPTION:
-- This test verifies that the types and subprograms specified for the
-- interface are present
--
-- APPLICABILITY CRITERIA:
-- If an implementation provides package Interfaces.C.Pointers, this
-- test must compile, execute, and report "PASSED".
--
--
-- CHANGE HISTORY:
-- 06 Dec 94 SAIC ACVC 2.0
-- 28 Feb 96 SAIC Added applicability criteria.
