We could (if somebody is willing to find and change all the relevant
declarations). But that doesn't do anything at all to clarify which
printf format code to use for them.
Note that the POSIX snippet you quote doesn't actually guarantee that
pid_t is not wider than "long". So while we could convert all these
places to
printf("...%ld...", (long) pid_t_variable_here);
that's still not formally correct.
Since we have yet to see a platform where our current habit of casting
pids to int doesn't work just as well, I'm inclined not to bother
changing anything here.
