	(usleep): Return void.

1998-08-11  Roland McGrath  <roland@baalperazim.frob.com>

	* sysdeps/generic/if_index.c (struct if_freenameindex): Add forward
	decl to inhibit warning in if_freenameindex defn.

	* sysdeps/mach/hurd/ttyname_r.c (__ttyname_r): Remove unused variable.

	* sysdeps/mach/hurd/getdomain.c (getdomainname): Renamed from __ name.

	* sysdeps/mach/hurd/reboot.c: Include <sys/reboot.h>.
	* sysdeps/mach/hurd/getdents.c: Include <unistd.h>.
	* sysdeps/mach/hurd/sbrk.c: Include <unistd.h>.
	* sysdeps/mach/usleep.c: Likewise.

	* sysdeps/mach/hurd/bind.c (bind): Add a const.

	* sysdeps/mach/hurd/getdents.c (__getdirentries): Use prototype defn.
	* sysdeps/unix/bsd/init-posix.c (__init_posix): Likewise.
	* sysdeps/unix/bsd/times.c (timeval_to_clock_t): Likewise.
	* sysdeps/mach/hurd/reboot.c (reboot): Likewise.
	* sysdeps/mach/usleep.c (usleep): Likewise.
	* sysdeps/mach/hurd/chflags.c (chflags): Likewise.
	* sysdeps/mach/hurd/fchflags.c (fchflags): Likewise.
