+--
+-- 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.
