* Now uses autoconf

* Running under:
- Solaris 2.5.1
- Linux

* Compiles under (but doesn't run)
- Irix (pcap unable to open device -- don't know why)
- HPUX 9.0.4 (HPUX Streams interface missing.  Same for all pcap foo
  on the machine I used.)
- Ultrix (Not tested, as my ultrix machine doesn't have pf support.)


* Fails under
- SunOS -- no idea why, but the from/to in_addr copying crashes it.
