25 -- OBJECTIVE
26 -- Check the requirements of the revised 10.2.1(11) from Technical
27 -- Corrigendum 1 (originally discussed as AI95-00002).
28 -- A package subunit whose parent is a preelaborated subprogram need
29 -- not be preelaborable.
30 --
31 -- TEST DESCRIPTION
32 -- We create several preelaborated library procedures with
33 -- non-preelaborable package body subunits. We try various levels
34 -- of nesting of package and procedure subunits.

37 -- 29 JUN 1999 RAD Initial Version
38 -- 23 SEP 1999 RLB Improved comments, renamed, issued.
