25--
26-- OBJECTIVE:
27--      Check that the specifications of the package Interfaces.C are
28--      available for use.
29--
30-- TEST DESCRIPTION:
31--      This test verifies that the types and subprograms specified for the
32--      interface are present.  It just checks for the presence of
33--      the subprograms.  Other tests are designed to exercise the interface.
34--
35-- APPLICABILITY CRITERIA:
36--      If an implementation provides package Interfaces.C, this test
37--      must compile, execute, and report "PASSED".
38--
39--
40-- CHANGE HISTORY:
41--      06 Dec 94   SAIC    ACVC 2.0
42--      15 Nov 95   SAIC    Corrected To_C parameter list for ACVC 2.0.1.
43--      28 Feb 96   SAIC    Added applicability criteria.
