-- In Ada 95, the package Ada.Text_IO.Integer_IO is a subpackage of Text_IO.

-- to avoid loading the necessary code if Integer_IO is not instantiated.
-- See routine Rtsfind.Check_Text_IO_Special_Unit for a description of how
-- we patch up the difference in semantics so that it is invisible to the
-- Ada programmer.
