Reviewing the code, did you actually try the gai+IPv6 code?
Going in a for() loop iterating over res after getaddrinfo() returned
an error doesn't look safe, as I don't remember any guarantee about
the value of res in that case and the doc doesn't mention anything
In the IPv4 code, you'll end up printing an unrelated error message
"... (only IPv4 is supported)", because the if() you've modified
actually only checks that the returned address is IPv4.
I'm sorry, but I can't call that a good patch, and am reiterating my
request for a revert.
