| -- In Ada 95, the package Ada.Text_IO.Decimal_IO is a subpackage of Text_IO. |
| -- This is for compatibility with Ada 83. In GNAT we make it a child package |
| -- to avoid loading the necessary code if Decimal_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. |
