36--  In Ada 95, the package Ada.Text_IO.Integer_IO is a subpackage of Text_IO.
37--  This is for compatibility with Ada 83. In GNAT we make it a child package
38--  to avoid loading the necessary code if Integer_IO is not instantiated.
39--  See routine Rtsfind.Check_Text_IO_Special_Unit for a description of how
40--  we patch up the difference in semantics so that it is invisible to the
41--  Ada programmer.
