[issue2005] posixmodule expects sizeof(pid_t/gid_t/uid_t) <= sizeof(long)

Can you give an example of OS where pid_t, gid_t or uid_t type are longer than the long type?

(If I remember correctly, the "identifier" of a Windows process is an addresse, so it has a size of sizeof(void*), whereas long can be smaller on 64 bit Windows. But this issue looks to be specific to UNIX.)
