Hmmm, I have used a different vendor dependant API some time ago (can't
remember which one exactly) and recognized that such lists tend to be
inaccurate. So I like to try it on my own...

Nürnberg, Germany, and I guess you live somewhere in Northern Italy :-)

Yes, I've implemented a call to PacketGetVersion() now and will warn
users that they may experience problems if using an unknown WinPcap version.

I tried Ethereal with some older WinPcap versions beginning with 2.3. It
seems to be working well with all those versions, however I don't know
exactly why, when I look at your change log ;-)

The situation as I can see it: Compiling with a recent WinPcap version
is ok, and running can be done even with an older WinPcap version as well.

Perfect for me as compiling Ethereal is far less done than using on
windows (a usual windows user won't compile Ethereal but simply install it).
