Still, why such thing would be useful?

I just noticed that this thread started from "Problem with compiling 
libnfnetlink". Could you check that you have /usr/include/asm/types.h
installed? it seems that your system doesn't find the definition of
__u32.

It's true that this is defined in a kernel header but such file is usually
provided by the linux-kernel-header package, that is the case of debian.
I think that is a reasonable requirement to compile libnfnetlink.
