Issues building iptables-1.4.2 w/ linux 2.6.25 (and IMQ)

[Philip Prindeville <philipp_subx@redfish-solutions.com>]

I'm trying to build iptables 1.3.8 in a cross-compile environment for 
linux 2.6.25.19 on an x86, but I'm seeing:

Is this a known issue?  Is there a patch for this?

I tried bumping to 1.4.2, but that dies with a different issue:

This is with the 2.6.25.7 IMQ patches.

Building 1.4.1 also craps out similarly.

Anyone have a suggestion? I'm trying to update the distro to go from 
Linux 2.6.20 to 2.6.25 and don't have a lot of time to dig deeper.

Thanks,
