Hm. This is the kind of thing where a compiler warning could be useful. I took a quick look at gcc's manual, but it does not seem to have a warning for this particular mistake (argument names do not match between declaration and definition). That way, you could repeat yourself safely, since the repetition would be checked by the compiler.
