* sysdeps/mach/hurd/dup2.c: Fixed broken test in last change.

	* elf/dl-error.c (_dl_catch_error): Actually call the OPERATE
 	function.  Duh.

	* hurd/Makefile (distribute): Added hurdstartup.h.
	* hurd/hurd.h: Remove _hurd_startup decl.

	* hurd/hurd/ioctl.h (_HURD_HANDLE_IOCTLS): Use __attribute__
 	((__unused__)) instead of gratuitous self reference.

	* sysdeps/mach/hurd/dup2.c: Call _hurd_alloc_fd to expand the
 	table if FD2 doesn't fit.

	* sysdeps/mach/hurd/getdtsz.c: Return the RLIM_NOFILE soft limit,
 	not the current table size.

	* sysdeps/i386/init-first.c: New file.
	* sysdeps/stub/init-first.c: New file.
