That's what I expected.

So I've successfully updated traceroute6 to use all the right bits from
glibc and not touch /usr/include/linux/ at all.  tracepath and
tracepath6 are a bit harder, though, since they make use of Linux error
queues as defined in /usr/include/linux/errqueue.h.  I can't seem to
find any interface between the glibc headers and the kernel.  Does one
exist, or will these programs continue to require linux/errqueue.h?

It was almost that easy, but some types needed to be updated since the
code was using things like __u32, which is defined in linux/types.h.

noah
