+--  This package contains the routines for Ada.Text_IO.Float_IO that are
+--  shared among separate instantiations of this package. The routines in
+--  this package are identical semantically to those in Float_IO itself,
+--  except that generic parameter Num has been replaced by Long_Long_Float,
+--  and the default parameters have been removed because they are supplied
+--  explicitly by the calls from within the generic template. This package
+--  is also used by Ada.Text_IO.Fixed_IO, and Ada.Text_IO.Decimal_IO.
+
+private package Ada.Text_IO.Float_Aux is
+
+   procedure Load_Real
+     (File : File_Type;

+      Ptr  : in out Natural);

+   --  real literal value from the input file into Buf, starting at Ptr + 1.
