package body BC.Support.Unmanaged_Storage is

   type Default_Access_Type is access Integer;  -- arbitrary designated subtype

   --  In the subprograms below, we would use just
   --  Default_Access_Type'Storage_Pool but that GNAT 3.11b has an error in
   --  this area. Thanks to Gene Ouye <geneo@rational.com> for the idea.
