Thanks for the report.  I will add the missing structures to Cygwin.
They will not be available any time soon, though.

Don't do that.  Define the missing strcutures manually in your application
instead.

Also keep in mind that ip_mreq_source, ip_msfilter, in_pktinfo are only
available starting with Windows XP.  If you use them in your application,
it will not be backward compatible to NT4, W2K, or, FWIW, 95/98/Me.
