Thanks for the report. I'm looking at fixing this now (but to do it
nicely I decided to do a bigger rewrite of the whole rtnl type-system
logic, so not quite done yet).

I'd be happy with accepting a patch to missing.h to make this compile,
but it should all be redundant pretty soon, so maybe not worth the
effort.

Side note: we might want to revisit how old kernels we want to
support. Especially for building, we may want to just require
something a bit more recent (maybe 3.10 or 3.12)?

Cheers,

Tom
