dhcpd: fix an improper widening conversion We wanted to detect when tv_sec = unsigned1 - unsigned2 underflows by looking at tv_sec's sign. But if tv_sec is long and it is wider than unsigned, we get unsigned -> long conversion which is in this case never negative. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
