What I'm trying is something like this:

	if (proto != NULL) {
		struct protoent *protoent;

		protoent = getprotobyname(proto);
		if (protoent != NULL)
			addrhint.ai_protocol = protoent->p_proto;
		else
			log_error("getprotobyname(%s)", proto);
	}

	error = getaddrinfo(addr, service, &addrhint, &addrinfo);

Shouldn't it do the mapping of addrhint.ai_protocol=6 (tcp)
into ai_socktype = SOCK_STREAM?

Isn't this a bug of some sorts?
