A patch to bypass MS' sillyness with regard to IPv6 and
getaddrinfo().

The CURLDEBUG part is to avoid redefinition warning caused by
memdebug.h. If ENABLE_IPV6 isn't enabled, it doesn't matter since
we never call getaddrinfo(). Allthough we could to support weird protocols
like SOCK_RDM that Win-2K/XP has.
