No, this warning is not really an issue. I think there's already
a small patch in patch-o-matic to fix this compile warning.

Can you recompile the CuSeeMe module with debugging enabled ?
there's no need for a full kernel recompile.

Just edit net/ipv4/netfilter/ip_nat_cuseeme.c in the kernel tree
and change the lines:

#if 0
#define DEBUGP printk
#else
#define DEBUGP(format, args...)
#endif

into this (it's really just a one-line change):

#if 1
#define DEBUGP printk
#else
#define DEBUGP(format, args...)
#endif

then do (from your kernel source tree):

rm net/ipv4/netfilter/ip_nat_cuseeme.o
make SUBDIRS=net/ipv4/netfilter modules
make modules_install

then you can do 'rmmod ip_nat_cuseeme' and 'modprobe ip_nat_cuseeme'
again.

Debugging messages should be logged depending on your
syslog configuration. Most likely they will show
up in /var/log/messages. Can you copy-paste the
debugging messages ?

Thanks in advance,
Filip
