From 854f901f491ccda79aee11edc3d59109cb229d28 Mon Sep 17 00:00:00 2001
From: Lennart Poettering <lennart@poettering.net>
Date: Wed, 26 Oct 2005 21:27:40 +0000
Subject: * avahi-utils: replace python avahi-browse with a version written in
 C. * remove -Wunused from GCC command line and use "unused" attribute instead
 * remove AVAHI_CLIENT_S_FAILURE and AVAHI_CLIENT_S_INVALID since these
 event's are never forwarded to the client anyway * make use of
 AVAHI_GCC_NORETURN * really send eror code with StateChange DBUS signals *
 ignore EINTR in avahi_simple_poll_loop()
