--
-- OBJECTIVE:
--      Check that a compilation unit may not depend semantically
--      on two different versions of the same compilation unit.
--      Check the case where a library level instance depends on
--      a library level generic function whose body is changed.
--
-- TEST DESCRIPTION:
--      This test compiles a generic function, an instance of a generic
--      function that withs the first function and a main procedure that 
--      withs the instance.  Then a new version of the first generic function
--      is compiled (in a separate file, simulating editing and modification
--      of the unit).  Unless automatic recompilation is supported, this
--      test should fail to link. Otherwise, the test should recompile and
--      link the correct version of the withed function and report "PASSED"
--      at execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140200 (and include the results in the
--            program library).
--         2) Compile the file LA140201 (and include the results in the
--            program library).
--         3) Compile the file LA140202 (and include the results in the
--            program library).
--         4) Compile the file LA140203 (and include the results in the
--            program library).
--         5) Attempt to build an executable image.
--         6) If an executable image results, run it.
--
-- TEST FILES:
--      This test consists of the following files:
--         LA140200.A
--         LA140201.A
--      -> LA140202.AM
--         LA140203.A
--
-- PASS/FAIL CRITERIA:    
--      The test passes if a link time error message reports that 
--      LA140202 is missing or obsolete, or that LA14020_3 or LA14020_4
--      is missing or obsolete (optional) and no executable image
--      results.  The test passes if an executable image is produced
--      and reports "PASSED" (in the case where the implementation
--      supports automatic recompilation).            
--
--
-- CHANGE HISTORY:
--     01 MAY 95   ACVC 1.12   LA5008Q baseline version
--     23 JUN 95   SAIC        Initial version
--     29 FEB 96   SAIC        First revision after review
--     12 DEC 96   SAIC        Reorganized to permit automatic recompilation.
--                             Reworded objective. Moved instance to
--                             library-level and redesigned to use generic
--                             formal function. Fixed arithmetic errors.
