Subject: [PATCH] Correct return type of pdfork(2).

The pdfork(2) man page states:

	"pdfork() returns a PID, 0 or -1, as fork(2) does."

As it returns a PID, the return type should obviously be pid_t. As int
and pid_t have the same size on all architectures, this change does not
affect the ABI in any way.
