pflogd needing pcap-int.h

[Christoph Egger]

Hi!

  I'm trying to build pflogd for debian. Unfortunately it depends on
pcap-int.h which is kind of awkward for some reasons:

  - It could add incompatibility wiith changing pcap versions --
    potentially unnoticed
  - I don't really fancy having the pcap-dev package expose internal
    headers and using a copy sounds even worse in time of up-to-dateness
  - the pcap-int header somewhat depends on the config.h which we'd need
    to keep available

Below are the error messages when compiling with an empty pcap-int.h do
you see a chance of fullfilling pflogd's need with "official" API? Any
ideas how a clean solution would look like?

Thanks

  Christoph
