--
-- 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.
