Winsock2.h and Multicast...missing definitions

I am currently trying to write some networking code in Visual C++ while trying to maintain cross platform compatibility.  My current issue is that I am trying to figure out how to setup a multicast connection and join and leave groups.  I already have some code which is just creating and binding a socket and then setting some options.  This stuff works fine, when I try to start playing with multi cast I start running into problems, such as winsock2.h does not define many of the multicast data structures and #defines, such as ip_mreq, and IP_ADD_MEMBERSHIP.  I found that these are defined in Ws2tcpip.h if I try to include this file I starti running into tons a of redfines.  What is the best approach to networking in windows while still maintaining maximal cross platform compatibility.  So I guess my first question is what do I need to include to get Multicast working, I would like to avoid all the WSA* calls.  What then is the best way to then starting join Multicast groups.

Thanks

sigh...I was doing out of order include I gues for the Ws2tcpip.h file, once I ensured that winsock2.h was include before Ws2tcpip I was then able to refrence the Multicast related structures.  So that still leaves me with my other question what steps do I take to join a group preferable without the WSA* functions.  Is there a good code snipet that demonstrates this?
