compiling 2.4.29 breaks with error

Trying to compile 2.4.29 on a PowerMac I end up like this:

Is this a bug in the kernel code, or did I do something wrong
configuring?

It seems that you configured both iptables (new packetfilter) and
ipchains (old packetfilter) support into your kernel. Either build them
as module or decide for one.

yes, yiou are right. It happened because I had taken the stock config and
switched off module support using menuconfig. This made everything
previously configured as a module now compiled in staticly.
