	* misc/sys/cdefs.h (__errordecl, __va_arg_pack_len): Define.
	* io/fcntl.h: Include bits/fcntl2.h when __va_arg_pack_len
	is defined rather than when not C++.
	* io/bits/fcntl2.h (__open_alias, __open64_alias, __openat_alias,
	__openat64_alias): New redirects.
	(__open_too_many_args, __open_missing_mode, __open64_too_many_args,
