I think what he was asking is this: Since pid_t has to be a signed integer
type, but gcc does not accept %d for it, then it could be that pid_t is wider
than an int, so casting it to int would potentially lose information.
(Btw., the Windows port defines pid_t as unsigned long; that's surely wrong.)
