This is unlikely to be fixed in the kernel header, but in the
applications themselves.

In this case, I see no changes to errqueue.h itself since 2012,
but the uapi did go through some changes in 3.17 .. but then no
more changes for 3.18.

So if this is broken, socat should be breaking on every distro that
uses 3.17+ kernel headers.

I see that our socat is still the latest.

.. and a quick search shows a fix:

http://sources.gentoo.org/cgi-bin/viewvc.cgi/gentoo-x86/net-misc/socat/files/socat-1.7.2.4-linux-3.17.patch?view=markup

Did you want me to try a build and stack up the fix ?
