	* sysdeps/mach/hurd/bind.c: Translate EEXIST from dir_link into
	EADDRINUSE.  If translated node doesn't grok ifsock protocol,
	return EADDRINUSE.

	* sysdeps/mach/hurd/connect.c: Make address arg
	`const struct sockaddr_un *'.
	The redecl is kosher and avoids another variable for AF_LOCAL case.
	* sysdeps/mach/hurd/sendto.c: Likewise.
	* sysdeps/mach/hurd/bind.c: Likewise.

	* socket/sys/socket.h (__SOCKADDR_ARG): Enable transparent_union
 	code for GCC >= 2.7; use __transparent_union__ for name safety;
 	add several sockaddr flavors.
	(__SOCKADDR_ALLTYPES, __SOCKADDR_ONETYPE): New macros used in
	constructing the transparent union declarations.
	(__CONST_SOCKADDR_ARG): New type (or macro if not GCC 2.7).
	(bind, connect, sendto): Make the sockaddr argument use that.
