IPv6 on windows?

[PigNuggetz]

Ok, I'm looking into socket programming on windows, and I feel that what I'm resorting to is very unorthodox. I was trying to compile functions from the socket library with mingw32 but from what I understood mingw32 still doesnt support the latest functionalty of that library, So I was forced to switch to the microsoft compiler cl. Now I wrote a small program that is supposed to find the IP address of a domain name, basically activates the DNS lookup. However in windows it fails to retrieve the IPv6 addresses, It only gives me IPv4. I Want to write my application on IPv6. Why my programm works on linux with IPv6 but on windows it doesnt??

here is code, enjoy
