--
-- 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 generic package body depends
--      on a library level generic package body that is changed.
--
-- TEST DESCRIPTION:
--      This test compiles a generic package and its body, and a
--      procedure that withs the generic package.  Then a new 
--      version of the generic package body 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 with package
--      withed package and report "PASSED" at execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140180 (and include the results in the
--            program library).
--         2) Compile the file LA140181 (and include the results in the
--            program library).
--         3) Compile the file LA140182 (and include the results in the
--            program library).
--         4) Compile the file LA140183 (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:
--         LA140180.A
--         LA140181.A
--      -> LA140182.AM
--         LA140183.A
--
-- PASS/FAIL CRITERIA:    
--      The test passes if a link time error message reports that 
--      LA14018_0.utils_18 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   LA5008N baseline version
--     16 JUN 95   SAIC        Initial version
--     07 DEC 96   SAIC        Modified unit names and prologue to conform
--                             to coding conventions. Moved instantiation
--                             of utils_18 to avoid potential Program_Error.
--                             Moved LA14018_0 to a separate file.
--
--!
                  
separate (LA14018_0)        -- This dependency must be resolved
                            -- after LA140181.A is compiled.
