 In gnats/gnatsd.c, line 623:
   if ((s.sin_family != AF_INET) && (s.sin_family != AF_INET6))
 
 There should be an autoconf check for ipv6.
 
>Fix:

add the autoconf check or change that to:

  if ((s.sin_family != AF_INET)
#ifdef AF_INET6
  && (s.sin_family != AF_INET6)
#endif
     )

(though AF_INET6 might be defined as an enum on some systems).
