From 200ff9dc5235d1465c5891e7eaa877a9978bc16a Mon Sep 17 00:00:00 2001
From: Gerald Combs <gerald@wireshark.org>

Subject: Pick up some fixes and enhancements from
 http://cvs.fedora.redhat.com/viewcvs/rpms/ethereal/FC-4/:

In the LPD dissector, make lpd_client_code a value_string so that we
don't segfault.  Do the same for lpd_server_code, although it's not
strictly necessary.

Check to see if htmlview is installed, and use it as our HTML viewer.

The Fedora RPM has other patches, but I'm not sure if they should
be applied.
