-- A default storage pool that uses the pool of an arbitrary

-- <DL><DT><STRONG>
-- Tasking semantics:</STRONG><DD>
-- As all pools, fully task safe.</DL>

-- Storage semantics:</STRONG><DD>
-- It's a <EM>storage pool</EM>, so of course it does dynamic storage

-- (Ada 95 *is* lacking a standardized feature to somehow define a
-- "default" storage pool which, when given in a representation clause,
-- would effectively make the system use whatever pool it'd use if there
-- was no representation clause. It turns out that GNAT at least seems to
-- use one pool for all types, so using 'Standard_Pool' below for the
-- instantiations of the container packages works all right.)
