Why do you need to *substitute* the parameters in the string at all? 

Without substitution, the following seems to work fine:

  Ada.Text_IO.Put_Line("Parsing "         & File_Name & 
                       " failed on line " & To_String(Line_Number) & 
                       ".");

Of course, you still have to write your 

  function To_String(Line_Number: Line_Number_Type) return String;

... or you just use Line_Number'Image.
