If Windows API is documented to have such a function, you should be able find it in the w32api package in Cygwin. As for the "literal" representation, the only "standard" and documented IPv6 DNS notation is in the .ip6.arpa domain (the analog for IPv4's "in-addr.arpa"). Microsoft seems to have uniquely "enhanced" that convention to use a more compact notation... Even though it says it resolves internally without DNS on Windows, this convention is not likely portable (and will cause an actual DNS hit on other platforms that do not specially recognize ".ipv6-literal.net" -- unlike the treatment of ".ip6.arpa"). And a likely result of that is going to be "NXDOMAIN" (domain does not exist).
