Yeah, well that is not strictly true. We call it IPv6 support but you can
indeed use getaddrinfo() just fine even without IPv6 enabled.

--disable-ipv6 will make configure pick a gethostbyname_r() alternative
instead, and if you still get errors pointing out getaddrinfo() I would say
that you seem to have multiple instances of libcurl and you're not replacing
the one that errors for you.

Are you really meaning gethostbyname() explicitly, I mean without the _r ?
