26-- OBJECTIVE:
27--      Check that a compilation unit may not depend semantically
28--      on two different versions of the same compilation unit.
29--      Check the case where a unit depends on a package whose
30--      declaration is changed.
31--
32-- TEST DESCRIPTION:
33--      This test compiles the specification of a package containing
34--      the specification of a procedure.  Then it compiles the body
35--      of the package containing the body of the procedure and the
36--      main test procedure.  The main procedure withs the first
37--      package and calls the procedure in the first package.  Then,
38--      the withed package specification is changed and recompiled.
39--      Unless automatic recompilation is supported, this test should
40--      fail to link.  Otherwise, the test should recompile the package
41--      body and main procedure, link the correct versions of the unit,
42--      and report "PASSED" at execution time.
43--
44-- SPECIAL REQUIREMENTS:
45--      To build this test:
46--         1) Compile the file LA140020 (and include the results in the
47--            program library).
48--         2) Compile the file LA140021 (and include the results in the
49--            program library).
50--         3) Compile the file LA140022 (and include the results in the
51--            program library).
52--         4) Attempt to build an executable image.
53--         5) If an executable image results, run it.
54--
55-- TEST FILES:
56--      This test consists of the following files:
57--         LA140020.A
58--      -> LA140021.AM
59--         LA140022.A
60--
61-- PASS/FAIL CRITERIA:
62--      The test passes if a link time error message reports that
63--      LA140020_0 is missing or obsolete and no executable image
64--      results.  The test also passes if an executable image is produced
65--      and reports "PASSED" (in the case where the implementation supports
66--      automatic recompilation).

71--     08 MAY 95   SAIC        Initial version
72--     16 NOV 96   SAIC        Changed unit and file names to conform to
73--                             coding conventions.
74--     07 DEC 96   SAIC        Moved LA140020_0 to a separate file.
