I've found the reason for this build breakage, and noted that it only 
affects kernels with TCPDEBUG.
The issue is that ostadte , tcp_saveipgen and tcp_savetcp are declared 
at the top of tcp_input() , which was fine when tcp_input and 
tcp_do_segment() was one function.  When tcp_input() was split, the 
declarations stayed, but the new tcp_do_segment() has references to them 
as well.
