I'm compiling on Solaris x86 v2.6.  Pids, uids, & gids are all longs
here (which just happens to be the same physical size as an int, but
that's beside the point).

For maximum portability, the code should always cast a system-defined
type (such as pid_t) when combining it with a fixed-size type format
string (such as %d or %ld).  Casting it up to "long" ensures that no
data is lost (at least until "long long" pids come about :-) ).
