If you do not want to add it to the CFLAGS in the Makefile by hand, the
simplest way is to add it to SOLARIS2 in buildsunos (because CFLAGS is
deeply wrapped in the MFLAGS). I don't think it will disturb if not required
in other Solaris versions.

The libpcap version is 0.8.1, afaik the most recent one. Also the problem
is not libpcap as such but fil.c, lines 117-119:
#if defined(IPFILTER_BPF) && defined(_KERNEL)
# include <net/bpf.h>
#endif
There is simply no net/bpf.h anywhere, at least in Solaris 7 and 8.
Or must -DIPFILTER_BPF simply be omitted in Solaris? Then everything builds
o.k.; but does it work as it should?
(libpcap uses the dlpi interface rather than bpf.)
