Compiling routing algo written for 2.4 kernel, with 2.6 kernel

I am upgrading the kernel of a linux-router from 2.4.21 to 2.6.22. The routing algorithm is a proprietary one. While compiling it with the new kernel, I got the following error:

Code:

In file included from /lib/modules/2.6.22.2/build/include/asm/thread_info.h:16,
                 from /lib/modules/2.6.22.2/build/include/linux/thread_info.h:21,

/lib/modules/2.6.22.2/build/include/asm/processor.h:83: error: requested alignment is not a constant

In the 2.4.21 /lib/modules/`uname -r`/include/linux directory, skbuff.h is not included from if_ether.h, but in 2.6.22 it is. How should I tackle this error?
