Just sent them a notification :)

Bang on !!!!

That was the first thing I had tried.

The "#defines" are needed in all the avahi-modules (avahi-core,
avahi-daemon, etc.), so it needs to have itself pre-processed from the
common "avahi-common" module. Thankfully, the two "#defines" are present in
"avahi-common/defs.h".

This "avahi-common" is the basic common module, which is linked to other
modules (avahi-core, avahi-daemon, etc)

So far, so good.


But.. the problem starts now..

If the two additional values are read from the "static int
load_config_file(DaemonConfig *c)" method in "avahi-daemon/main.c" (via
"/etc/avahi/avahi-daemon.conf"), that does not work out.
Reason is that, because "avahi-daemon" requires "avahi-core" to complete
its linking process, whereas "avahi-core" would need "avahi-daemon" to
complete its linking process (since the two values will be read from the
context of "avahi-daemon").

That puts us in a catch-22 situation.

So, actually, the right place to load the complete config is in
"avahi-common" module; but as of now, even in F17, the "static int
load_config_file(DaemonConfig *c)" method resides in the "avahi-daemon"
module :\

Anyways, I loaded the two required variables (without needing the methods
of "avahi-daemon" module) from the context of "avahi-common".
