* sysdeps/posix/system.c (do_system): New function, guts broken out of
__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.
