__libc_system.
	(__libc_system): Call it, putting just the line == NULL test here.

	* include/libc-symbols.h (__hidden_proto): Add extern keywords so
	variables work right.

	* elf/dl-open.c (dl_open_worker): Use _ macro instead of gettext.
	* elf/dl-close.c (_dl_close): Likewise.

	* include/netinet/in.h: Use libc_hidden_proto for bindresvport,
	in6addr_any, in6addr_loopback.  Remove decls for
	bindresvport_internal, in6addr_any_internal, in6addr_loopback_internal.
	* sunrpc/svc_udp.c (svcudp_bufcreate): Nix INTUSE for bindresvport.
	* sunrpc/svc_tcp.c (svctcp_create): Likewise.
	* sunrpc/clnt_udp.c (clntudp_bufcreate): Likewise.
	* sunrpc/bindrsvprt.c: Change INTDEF to libc_hidden_def.
	* inet/in6_addr.c: Change INTVARDEF to libc_hidden_def.
	* sysdeps/posix/getaddrinfo.c (gaih_inet): Nix INTUSE for
	in6addr_loopback.
	* inet/gethstbyad_r.c (PREPROCESS): Nix INTUSE for in6addr_any.

	* include/netinet/ether.h: Use libc_hidden_proto for ether_ntoa_r,
	ether_aton_r.
	* inet/ether_aton_r.c: Add libc_hidden_def.
	* inet/ether_ntoa_r.c: Likewise.

	* include/rpc/auth.h: Use libc_hidden_proto for getnetname,
	netname2user, host2netname.
	* sunrpc/netname.c: Add libc_hidden_def.

	* include/netdb.h: Use libc_hidden_proto for innetgr, rcmd_af,
	rexec_af, rresvport_af, ruserok_af.
	* inet/rcmd.c: Add libc_hidden_def.
	* inet/getnetgrent_r.c: Likewise.
