Libpcap

- Add support for HP-UX. Resulted from code contributed by Tom Murray
(tmurrayhpindck.cup.hp.com) and Philippe-Andri Prindeville
(philippres.enst.fr)

- Update INSTALL with a reminder to install include files. Thanks to
Mark Andrews (mandrewsaw.sgi.com)

- Fix bpf compiler alignment bug on the alpha.

- Use autoconf to detect architectures that can't handle misaligned
accesses.

- Added loopback support for snoop. Resulted from report Steve
Alexander (scaengr.sgi.com)

- Fixed compiler and optimizer bugs. The BPF filter engine uses unsigned
comparison operators, while the code generator and optimizer assumed
signed semantics in several places. Thanks to Charlie Slater
(cslaterimatek.com) for pointing this out.

- Removed FDDI ifdef's, they aren't really needed. Resulted from report
by Gary Veum (veumboa.gsfc.nasa.gov).

- Add pcap-null.c which allows offline use of libpcap on systems that
don't support live package capture. This feature resulting from a
request from Jan van Oorschot (j.p.m.voorschotet.tudelft.nl).

- Make bpf_compile() reentrant. Fix thanks to Pascal Hennequin
(Pascal.Hennequinhugo.int-evry.fr).

- Port to GNU autoconf.

- Fix pcap-dlpi.c to work with isdn. Resulted from report by Flemming
Johansen (fsjcsd.cri.dk).

- Handle multi-digit interface unit numbers (aka ppa's) under dlpi.
Resulted from report by Daniel Ehrlich (ehrlichcse.psu.edu).

- Fix pcap-dlpi.c to work in non-promiscuous mode. Resulted from report
by Jeff Murphy (jcmurphyacsu.buffalo.edu).

- Add support for "long jumps". Thanks to Jeffrey Mogul
(mogulpa.dec.com).

- Fix minor problems when compiling with BDEBUG as noticed by Scott
Bertilson (scottunet.umn.edu).

- Declare sys_errlist "const char *const" to avoid problems under
FreeBSD. Resulted from report by jhereden.com.

- Add missing variable declaration missing from 0.0.6

- Workaround for problems when pcap_read() returns 0 due to the timeout
expiring.

- Change configuration to not use gcc v2 flags with gcc v1.

- Fixed a bug in pcap_next(); if pcap_dispatch() returns 0, pcap_next()
should also return 0. Thanks to Richard Stevens (rstevensnoao.edu).

- Fixed configure to test for snoop before dlpi to avoid problems under
IRIX 5. Thanks to J. Eric Townsend (jetabulafia.genmagic.com).

- Hack around deficiency in Ultrix's make.

- Fix two bugs related to the Solaris pre-5.3.2 bufmod bug; handle
savefiles that have more than snapshot bytes of data in them (so we
can read old savefiles) and avoid writing such files.

- Added checkioctl which is used with gcc to check that the
"fixincludes" script has been run.

- Fixed configure to test for snoop before dlpi to avoid problems under
IRIX 5. Thanks to J. Eric Townsend (jetabulafia.genmagic.com).
