sys_time: port to OpenBSD * lib/sys_time.in.h: Simply delegate to the system's header in the BSDish cases as well. Problem reported by Mike Miller in <http://lists.gnu.org/archive/html/bug-gnulib/2013-08/msg00016.html>. * tests/test-sys_select.c, tests/test-sys_time.c (verify_tv_sec_type): Allow platforms like 64-bit OpenBSD where timeval's tv_sec is wider than time_t.
