This really looks like a Windows 10 1507 bug so it's tempting to add a
broken((hinttests[i].family == AF_UNSPEC && hinttests[i].sock_type != 999) &&
...).

But it's strange that there is no failure on index 6 for instance since it's
the same test after line 2455 (hint.ai_family = AF_INET6):

0:     {AF_UNSPEC, SOCK_STREAM, IPPROTO_TCP, 0}, /* 0 */
6:     {AF_INET,   SOCK_STREAM, IPPROTO_TCP, 0},
