I vaguely remind such a conversation in the past with reports of getaddrinfo() not returning what was expected. Maybe that's something to consider for a next major version (eg: 1.7). However we could possibly have something intermediary for 1.6 : having the option to force to use GAI and not use it by default. That wouldn't break existing setups and would allow those who need it to use it as-is. We'd basically build with "USE_GHBN_FIRST" in addition to "USE_GETADDRINFO", it would then use only gethostbyname except if the option forces the other one. Does this sound like a reasonable option ?
