--*

--

-- OBJECTIVE:

--      Check that the specifications of the package Interfaces.C are

--      available for use.

--

-- TEST DESCRIPTION:

--      This test verifies that the types and subprograms specified for the

--      interface are present.  It just checks for the presence of

--      the subprograms.  Other tests are designed to exercise the interface.

--

-- APPLICABILITY CRITERIA:

--      If an implementation provides package Interfaces.C, this test

--      must compile, execute, and report "PASSED".

--

--

-- CHANGE HISTORY:

--      06 Dec 94   SAIC    ACVC 2.0

--      15 Nov 95   SAIC    Corrected To_C parameter list for ACVC 2.0.1.

--      28 Feb 96   SAIC    Added applicability criteria.
