Nice. That is working for me. Thanks for the tip.

Just one note on this solution: In singleipconnect() (lib/connect.c)
after the call to the opensocket callback, just below the /* FIXME */
note, the code assumes AF_INET or AF_INET6, and the return value of
Curl_inet_ntop() isn't checked prior to passing addr_buf to infof().
