I think we all agree.

There is no reason at all (in my eyes) to worry about the size
of a pid. One writes
        pid_t p = getpid();
and all is OK.

But then, what about printing? It seems to me that a routine like

void outpid(pid_t p) {
        if (p < 0) {
                putchar('-');
                outpid(-p);
        } else {
                if (p)
                        outpid(p/10);
                putchar('0'+(p%10));
        }
}

prints a pid without making assumptions on the size of a pid.
