According to source code, UDP listening is set up also when forwarding
is activated (@<hostname> instruction in /etc/syslogd.conf).
I believe the following patch correctly deals with the issue by using
bind system call only when remote listening is enabled by
configuration and not when forwarding alone is enabled (which is
currently done in source code).
