Both the same. Kernel 2.6.11.12 and ipset 2.2.5-2005103 ( but I have no problems compiling the user space program ), gcc 3.4.3. Turning off ip_set_iptree will finally allowed me to get a successful compilation. I have not been having luck with newer kernels because it will hit other errors first before reaching compilation of ipset. Cheers.
