--
-- OBJECTIVE:
--      Check that a compilation unit may not depend semantically
--      on two different versions of the same compilation unit.
--      Check the case where a generic function depends on a 
--      library level package.
--
-- TEST DESCRIPTION:
--      This test compiles a package specification, then a generic 
--      function specification and body that withs the package, 
--      followed by a procedure that makes a call to an instance of
--      the generic function.  Then, the package specification is
--      recompiled, making the body of function LA14004_1 obsolete.
--      Unless automatic recompilation is supported this test should fail
--      to link.  Otherwise, the test should recompile and link 
--      the correct version of the withed package and report
--      "PASSED" at execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140040 (and include the results in the
--            program library).
--         2) Compile the file LA140041 (and include the results in the
--            program library).
--         3) Compile the file LA140042 (and include the results in the
--            program library).
--         4) Attempt to build an executable image.
--         5) If an executable image results, run it.
--
-- TEST FILES:
--      This test consists of the following files:
--         LA140040.A
--      -> LA140041.AM
--         LA140042.A
--
-- PASS/FAIL CRITERIA:                
--      Expect a link-time error message that the body of generic 
--      function LA14004_1 is missing or obsolete.  If automatic
--      recompilation is supported, and an executable image is 
--      built, expect a "PASSED" message from execution.
--
-- CHANGE HISTORY:
--     09 MAY 95   SAIC    Initial version
--     10 DEC 96   SAIC    Reorganized to permit automatic recompilation.
