26-- OBJECTIVE:
27--      Check that a compilation unit may not depend semantically on two
28--      different versions of the same compilation unit.  Check the case
29--      where a generic package body depends on a generic package
30--      specification.
31--
32-- TEST DESCRIPTION:
33--      This test compiles a generic package specification and body,
34--      followed by a procedure that makes a call to a procedure
35--      contained inside the generic package.  Then, the generic package
36--      specification is recompiled, making the body of the generic
37--      package obsolete.  Unless automatic recompilation is
38--      supported this test should fail to link.  Otherwise, the test should
39--      recompile and link the correct version of the units and report
40--      "PASSED" at execution time.
41--
42-- SPECIAL REQUIREMENTS:
43--      To build this test:
44--         1) Compile the file LA140050 (and include the results in the
45--            program library).
46--         2) Compile the file LA140051 (and include the results in the
47--            program library).
48--         3) Compile the file LA140052 (and include the results in the
49--            program library).
50--         4) Compile the file LA140053 (and include the results in the
51--            program library).
52--         5) Attempt to build an executable image.
53--         6) If an executable image results, run it.
54--
55-- TEST FILES:
56--      This test consists of the following files:
57--         LA140050.A
58--         LA140051.A
59--      -> LA140052.AM
60--         LA140053.A
61--
62-- PASS/FAIL CRITERIA:
63--      Expect a link-time error message that the body of generic
64--      package LA14005_1 is missing or obsolete.  If automatic
65--      recompilation is supported, and an executable image is
66--      built, expect a "PASSED" message from execution.
