I discovered this bug while searching for something else and it is relevant to
a bug that I am directly working on (Bug #7929).  Are you entirely certain that
this functionality can be enabled on Windows?  MSDN indicates that IP_PKTINFO
is only supported for getsockopt() and not setsockopt(), so I have previously
ignored the possibility that a user application could set the IP_PKTINFO
option.

Adjusting for this scenario should be a simple matter in what I'm working on,
but if you really can set this option then I will have to do some additional
work.  So, if you could confirm this (and preferably provide links to some
applications that use this feature) then I would greatly appreciate it.
