cyswin/socket.h:

struct msghdr
{
	void	*	msg_name;	/* Socket name			*/
	int		msg_namelen;	/* Length of name		*/
	struct iovec *	msg_iov;	/* Data blocks			*/
	int		msg_iovlen;	/* Number of blocks		*/
	void	*	msg_accrights;	/* Per protocol magic (eg BSD file descriptor passing) */
	int		msg_accrightslen;	/* Length of rights list */
};

http://www.opengroup.org/onlinepubs/009695399/basedefs/sys/socket.h.html:

void          *msg_name        Optional address. 
socklen_t      msg_namelen     Size of address. 
struct iovec  *msg_iov         Scatter/gather array. 
int            msg_iovlen      Members in msg_iov. 
void          *msg_control     Ancillary data; see below. 
socklen_t      msg_controllen  Ancillary data buffer len. 
int            msg_flags       Flags on received message.

problems:

1. msg_flags is missing
2. msg_control is renamed msg_accrights
3. msg_controllen is renamed msg_accrightslen
