+--
+-- 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.
