Does cygwin support the setsockopt() - IP_PKTINFO to retreive the destination 
address of a incomming UDP packet received via recvmsg()?  I have made 
numberous attempts but CMSG_FIRSTHDR() always returns NULL. The same code 
works find under linux.  I'm guessing that cygwin is using winsock underneath 
and I beleive this would only be available under winsock 2.2.  Is there a 
means to build cygwin to complile with this version of winsock?

Bill
