        * hurd/hurdchdir.c (_hurd_change_directory_port_from_name):
        Allocate three, not two, more than LEN when appending '/.'.
        * sysdeps/mach/hurd/chroot.c (chroot): Likewise.  Don't check
        if NAME ends with '/.' if it is shorter than 2 chars.

	* mach/Makefile ($(mach-syscalls:%=$(objpfx)%.S)): Make the generated
	files #include <sysdep.h> instead of <mach/machine/syscall_sw.h>.
