--
-- 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 package depends on another
--      generic package specification.
--
-- TEST DESCRIPTION:
--      This test compiles a generic package specification, then
--      compiles a generic package specification and body, 
--      followed by a procedure that makes a call to a procedure
--      contained inside the second generic package.  Then, the
--      first generic package specification is recompiled, 
--      making the body of the generic package LA140060 obsolete.
--      Unless automatic recompilation is supported this test should 
--      fail to link.  Otherwise, the test should recompile and link 
--      the correct version of the units and report "PASSED" at 
--      execution time.
--
-- SPECIAL REQUIREMENTS:
--      To build this test:
--         1) Compile the file LA140060 (and include the results in the
--            program library).
--         2) Compile the file LA140061 (and include the results in the
--            program library).
--         3) Compile the file LA140062 (and include the results in the
--            program library).
--         4) Compile the file LA140063 (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:
--         LA140060.A
--         LA140061.A
--      -> LA140062.AM
--         LA140063.A
--
-- PASS/FAIL CRITERIA:                
--      Expect a link-time error message that the body of generic
--      package LA14006_1 is missing or obsolete.  If automatic
--      recompilation is supported, and an executable image is 
--      built, expect a "PASSED" message from execution.
--
--
-- CHANGE HISTORY:
--     01 MAY 95   ACVC 1.12   LA5008K baseline version
--     09 MAY 95   SAIC        Initial version
--     17 NOV 96   SAIC        Modified unit names and prologue to conform
--                             to coding conventions.
--     07 DEC 96   SAIC        Moved LA14006_0 to a separate file. Added
--                             pragma Elaborate to context clause of LA14006_2.
