The appropriate notice for acconfig.h is probably the BSD copyright 
notice in other files; if so, we could probably put it in.

I don't know what the appropriate copyright and license notice would be 
for pcap-enet.c - I suppose one could ask Rayan Zachariassen.  However, 
given that

        1) it's not compiled into any version of libpcap;

	2) it wouldn't fit into any version of libpcap without change (it 
might have come from an old pre-libpcap version of tcpdump, and never 
been converted into a libpcap pcap-*.c module);

	3) I don't know whether anybody cares enough about whatever platform 
it supports (AIX on the IBM RT PC?) to keep it around;

perhaps the appropriate thing to do with it is to get rid of it.

There is, indeed, a configuration script generated by autoconf; that's 
what "configure" is - it's generated from "configure.in" and 
"aclocal.m4".

I assume it's just the license part of the BSD copyright notice.  
Perhaps it should be changed to 'the copyright notices in the source 
files", or something such as that, as not all of them have the same 
copyright notice.
