Yes, the hints should be passed as you indicate above. The version of the
test program I posted just happened to be one of the incarnations where I
had tested getaddrinfo() with no hints (I did a lot of different things to
figure out where the AIX problem was). I should proably have posted the
'hints' version instead, as it resembles the actual curl code better.

On AIX that doesn't happen, unfortunately -- even with proper hints the
ai_socktype is still 0. On the other hand you have now verified that
getaddrinfo() as used in curl actually works fine on Solaris :-)

Your other comment (in another posting) about the localhost/hostname
difference is interesting. I don't know much about ipv6 either, so
this is quite new territory for me too.
