The current CVS version of libpcap (which doesn't use <net/bpf.h> for
that purpose any more - it uses it only to define BPF ioctls and the
like) has the C++-protection stuff in it already.

Note that it's "tcpdump-workers () tcpdump org", not
"tcpdumpworkers () tcpdump org".

Note also that 99 44/100% of mail to patches () tcpdump org consists of
spam, so mail to that list is likely either not to be looked at
immediately or to be inadvertently deleted when purging spam;
bugs/patches/etc. should be submitted to SourceForge (which sends
notification mail to patches () tcpdump org, but also records the bug in
the SourceForge bug database).
