--
-- 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 body depends on a generic package 
--      specification.
--
-- TEST DESCRIPTION:
--      This test compiles a generic package specification and body, 
--      followed by a procedure that makes a call to a procedure
--      contained inside the generic package.  Then, the generic package
--      specification is recompiled, making the body of the generic
--      package 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 LA140050 (and include the results in the
--            program library).
--         2) Compile the file LA140051 (and include the results in the
--            program library).
--         3) Compile the file LA140052 (and include the results in the
--            program library).
--         4) Compile the file LA140053 (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:
--         LA140050.A
--         LA140051.A
--      -> LA140052.AM
--         LA140053.A
--
-- PASS/FAIL CRITERIA:                
--      Expect a link-time error message that the body of generic
--      package LA14005_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   LA5008I baseline version
--     09 MAY 95   SAIC        Initial version
--     08 NOV 96   SAIC        Unit naming correction
--     07 DEC 96   SAIC        Moved spec of LA14005_1 to a separate file.
