-- OBJECTIVE:
--      Check that a compilation unit may not depend semantically
--      on two different versions of the same compilation unit.
--      Check the case where a separate procedure depends
--      on a withed generic package that is changed.
--
-- TEST DESCRIPTION:
--      This test declares a package which contains a generic procedure GP,
--      the body of which is a subunit. The package also contains a procedure
--      P which instantiates GP and calls the instance. The instance itself
--      calls a procedure which is declared within the instance of a generic
--      package X. The test compiles each of these compilation units and the
--      main procedure, then compiles a new version of the generic package X
--      (in a separate file, simulating an 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 generic package X and report "PASSED" at execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140160 (and include the results in the
--            program library).
--         2) Compile the file LA140161 (and include the results in the
--            program library).
--         3) Compile the file LA140162 (and include the results in the
--            program library).
--         4) Compile the file LA140163 (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:
--         LA140160.A
--         LA140161.A
--      -> LA140162.AM
--         LA140163.A
--
-- PASS/FAIL CRITERIA:    
--      The test passes if a link time error message reports that 
--      LA14016_4.gen_def is missing or obsolete 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   LA5008L baseline version
--     16 JUN 95   SAIC        Initial version
--     07 DEC 96   SAIC        Modified unit names and prologue to conform
--                             to coding conventions. Restructured subunits
--                             to prevent potential Program_Error due to
--                             premature instantiation of gen_def. Moved
--                             LA14016_1 to a separate file. Added pragma
--                             Elaborate to context clause of LA14016_3.
