David, really POSIX is *far* from being a thin binding.

Your cool example is way more thin than mine :)

<<
   function Rename_File2 (Old_File, New_File : String) return Boolean
   is
      function MoveFile
        (Old_Name : String := Old_File & Character'Val (0);
         New_Name : String := New_File & Character'Val (0))
        return Boolean;
      pragma Import (StdCall, MoveFile, "MoveFileA");
   begin
      return MoveFile;
   end Rename_File2;
>>

Character'Val (0), Stdcall, pragma Import...

I won't call POSIX a framework since it is a _binding_ but yet not a
thin one. And yes in cross-platform environemnt it is definitly the 
choice, this is why I do use it!

Pascal.
