I would like to rename Math_Extension an extension of the
generic package Ada.Numerics.Generic_Elementary_Functions.

Thus, I created a generic child unit :

   generic
   package Ada.Numerics.Generic_Elementary_Functions.Extensions is

      function Log10 (X : Float_Type'Base) return Float_Type'Base;

      function Asin  (X : Float_Type'Base) Return Float_Type'Base
         renames Arcsin;

   end Ada.Numerics.Generic_Elementary_Functions.Extensions;

and I tried the following renaming :

   with Ada.Numerics.Generic_Elementary_Functions.Extensions;

   generic package Math_Extension renames
      Ada.Numerics.Generic_Elementary_Functions.Extensions;

The GNAT compiler refused it :

   >>> invalid prefix in selected component "Generic_Elementary_Functions".

I read that renaming is possible if realized in the parent unit, but
I can't do it because Generic_Elementary_Functions belongs to the
predefined library.

Could anyone help me ?

Thanks in advance.
