Sure, but say that someone uses whatever iproute2 version <=
iproute2-2.6.26 - which does not check for any ABI version numbering
AFAICS - and then it compiles whatever >= 1.4.2-rc1 by hand, then
jamal's ipt thing will not work as they use different ABIs.

I'm not talking on how to solve future interdependecy problems - which
you seems to have it done by exporting xtables as library - but the
problems that the size change of .name will trigger for some time.
