I realized it after send the patch. I prefer use uchar instead of suffix u. I known that gcc will complaint with a warning about pointer to data with different signess, but I think we are the programmers and not gcc, so using uchar is the way. Thinking a bit more about this, I don't know why we are using -Wall, because it moves people to follow the GNU criteria, that is the more suck criteria I know (I think it is because they come from the LISP world, and they want to see your code formatted as LISP, and force you to put a lot of unneded parenthesis ;).
