Um, I think:
	- You may include <stdio.h> as long as your new printf() has
	  compatible arguments. It's a Bad Thing, though, because
	  declaration in <stdio.h> doesn't really belong to your new
	  function.
	- You may also have your own function non-static. Then, it
	  depends on link-order which function (yours or libc's) is
	  used. Of course, that's horrible, too:)
