Hmmm ... one wonders how this could make it through gcc 3.3.1 without
any warning at all ;-) (and I have checked the binary code it
generated and it did what I meant, interesting)

The change:
- (u8 *) tcp -= frag_off;
+ tcp = (struct tcphdr *)((u8 *) tcp - frag_off);

(could also be written as '*((u8 **) &tcp) -= frag_off;' but that
would be really ugly ;-)

Thanks for the report, I have updated the patch and tar.gz package at
http://Xtrmntr.org/ORBman/tmp/nmap/
