-- 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 generic procedure
--      depends on library level procedure that is changed.
--
-- TEST DESCRIPTION:
--      This test compiles a procedure, a generic procedure that 
--      withs the first procedure and a main procedure that withs
--      the generic procedure.  Then, a new version of the  
--      procedure is compiled (in a separate file, simulating 
--      and editing modification to 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 LA140190 (and include the results in the
--            program library).
--         2) Compile the file LA140191 (and include the results in the
--            program library).
--         3) Compile the file LA140192 (and include the results in the
--            program library).
--         4) Compile the file LA140193 (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:
--         LA140190.A
--         LA140191.A
--      -> LA140192.AM
--         LA140193.A
--
-- PASS/FAIL CRITERIA:    
--      The test passes if a link time error message reports that 
--      LA140192 is missing or obsolete, or that LA14019_1 is 
--      missing or obsolete (optional) and no executable image
--      results.  The test also 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   LA5008P baseline version
--     23 JUN 95   SAIC        Initial version
--     29 JAN 96   SAIC        First revision after review
--     17 NOV 96   SAIC        Modified unit names and prologue to conform
--                             to coding conventions.
