+-- Under contracts F33600-87-D-0337, F33600-84-D-0280, MDA903-79-C-0687,
+-- F08630-91-C-0015, and DCA100-97-D-0025, the U.S. Government obtained
+-- unlimited rights in the software and documentation contained herein.
+-- Unlimited rights are defined in DFAR 252.227-7013(a)(19). By making
+-- this public release, the Government intends to confer upon all
+-- recipients unlimited rights equal to those held by the Government.
+-- These rights include rights to use, duplicate, release or disclose the
+-- released technical data and computer software in whole or in part, in
+-- any manner and for any purpose whatsoever, and to have or permit others
+-- to do so.

+--*
+--
+-- 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 non-generic package that is changed.
+--
+-- TEST DESCRIPTION:
+-- This test compiles a package, a generic package, a
+-- generic instantiation that withs both of the first two
+-- packages, and a main procedure that withs the instantiated
+-- generic package. Then, a new version of the first
+-- 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 withed package and report "PASSED" at
+-- execution time.
+--
+-- SPECIAL REQUIREMENTS:
+-- To build this test:
+-- 1) Compile the file LA140250 (and include the results in the
+-- program library).
+-- 2) Compile the file LA140251 (and include the results in the
+-- program library).
+-- 3) Compile the file LA140252 (and include the results in the
+-- program library).
+-- 4) Attempt to build an executable image.
+-- 5) If an executable image results, run it.
+--
+-- TEST FILES:
+-- This test consists of the following files:
+-- LA140250.A
+-- -> LA140251.AM
+-- LA140252.A
+--
+-- PASS/FAIL CRITERIA:
+-- The test passes if a link time error message reports that
+-- LA14025 is missing or obsolete, or that LA14025_2 is
+-- missing or obsolete (optional) and no executable image
+-- results. The test passes if an executable image is produced
+-- and reports "PASSED" (in case the implementation supports
+-- automatic recompilation).
+--
+--
+-- CHANGE HISTORY:
+-- 01 MAY 95 ACVC 1.12 LA5008V baseline version
+-- 06 JUL 95 SAIC Initial version
+-- 08 NOV 96 SAIC Unit naming correction
+-- 07 DEC 96 SAIC Moved LA14025_0 to a separate file. Added
+-- pragma Elaborate to context clause of
+-- LA14025_2.
