Cast execl*() NULL sentinels to (char *)
The NULL sentinel argument to the execl*() family of calls must be cast to (char *), as otherwise: - platforms where NULL is just 0 (not (void *)) would pass an int - (admittedly esoteric) platforms where NULL is (void *)0 and (void *) and (char *) have different memory layouts would pass the wrong kind of pointer Signed-off-by: Thomas Rast <trast@student.ethz.ch> Signed-off-by: Junio C Hamano <gitster@pobox.com>
