Update.
* inet/arpa/inet.h (inet_addr): Change return type to in_addr_t. (inet_lnaof): Likewise. (inet_netof): Likewise. (inet_network): Likewise. (inet_aton): Likewise. (inet_makeaddr): Change parameter types to in_addr_t. (inet_neta): Likewise. (inet_ntop): Change type of last parameter to socklen_t. (inet_aton): Only make available if __USE_MISC. (inet_neta): Likewise. (inet_net_ntop): Likewise. (inet_net_pton): Likewise. (inet_nsap_ntoa): Likewise. * inet/in.h: Define in_port_t type. Define in_addr_t type. (struct in_addr): Use in_addr_t in definition. (IN_CLASSA): Use cast to in_addr_t. (IN_CLASSB): Likewise. (IN_CLASSC): Likewise. (IN_CLASSD): Likewise. (IN_EXPERIMENTAL): Likewise. (IN_BADCLASS): Likewise. (INADDR_ANY): Likewise. (INADDR_BROADCAST): Likewise. (INADDR_NONE): Likewise. (INADDR_LOOPBACK): Likewise. (INADDR_UNSPEC_GROUP): Likewise.

(struct sockaddr_in6): Use in_port_t for sin6_port element. Use uint8_t instead of u_int8_t. * resolv/inet_addr.c (inet_addr): Change return type to in_addr_t. Call __inet_aton instead of inet_aton. (__inet_aton): Renamed from inet_aton. Add weak alias under old name. * resolv/netdb.h (gethostbyname2): Define only is __USE_MISC. (innetgr): Likewise. (struct addrinfo): Use socklen_t for ai_addrlen element. * sysdeps/unix/sysv/linux/bits/in.h (IPV6_MTU_DISCOVER, IPV6_MTU, IPV6_RECVERR): New defines.
