Hi
Marcelo can you apply this patch? for work with IP Masquerade.

Reference:
http://lists.netfilter.org/pipermail/netfilter-devel/2002-November/009928.html

In begin, I apply this patch on redhat 7.3 box and thought this is a
specific problem of RedHat compiler, but I see exactly the same 
dependency dropped on a slackware-9.1 with kernel 2.4.25 and gcc3.3, do
me a favor and apply this mini patch.
