Thanks for your encouraging input. I applied my patch. A neat side-effect of this work is that the net.cc source code got about 18K smaller: I realized that we dropped support for all systems which didn't come with the getaddrinfo/getnameinfo/freeaddrinfo functions, so I got rid of the weird autoload code of these functions and the entire W. Richard Stevens implementation, which I only added as a replacement for older systems.
