I am using gcc version egcs-2.91.66 on Red Hat 6.2, and gcc version 2.96 
on Red Hat 7.3 for most development.

However, the above problem is related to the versions of gcc. Markus 
probably used a non-standard kernel source, which changes the function
of ip_select_ident. The solution is to adapt the ip_select_ident call in 
the ip_vs_tunnel_xmit to the new prototype of ip_select_ident, or to get a 
standard kernel and apply the IPVS patch on it.
