* m4/sys_time_h.m4 (gl_HEADER_SYS_TIME_H_BODY): Allow struct timeval even if tv_sec is wider than time_t. This allows OpenBSD 5.1 amd64 and fixes an Emacs porting glitch with utimens.c, as without this patch gnulib replaces struct timeval and OpenBSD futimes therefore has a type mismatch. * doc/posix-headers/sys_time.texi: Mention this.
