--
-- 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 instantiation depends on
--      a generic package instantiation that is changed.
--
-- TEST DESCRIPTION:
--      This test compiles a generic package, a generic  
--      instantiation of the generic package, another generic   
--      package, a generic instantiation of the second generic  
--      package that withs the first generic instantiation 
--      packages, and a main procedure that withs the instantiated 
--      generic package.  Then, a new version of the first generic  
--      package is compiled (in a separate file, simulating 
--      editing and 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 instantiation and report "PASSED" at 
--      execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140260 (and include the results in the
--            program library).
--         2) Compile the file LA140261 (and include the results in the
--            program library).
--         3) Compile the file LA140262 (and include the results in the
--            program library).
--         4) Compile the file LA140263 (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:
--         LA140260.A
--         LA140261.A
--      -> LA140262.AM
--         LA140263.A
--
-- PASS/FAIL CRITERIA:    
--      The test passes if a link time error message reports that 
--      LA140260 is missing or obsolete, or that LA14026_5 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   LA5008W baseline version
--     06 JUL 95   SAIC        Initial version
--     18 NOV 96   SAIC        Modified unit names and prologue to conform
--                             to coding conventions.
--     07 DEC 96   SAIC        Moved LA14026_3 to a separate file. Added
--                             pragma Elaborate to context clause of LA14026_5.
