Yes. I am working on MFC'ing the patch (r221333) to stable/8 so that it
doesn't delete the ones in /usr/include/nfs.

Having said that, to the best of my knowledge (I looked a while back),
nothing in /usr/src outside of the kernel includes them. Also, I can't
think of any reason why a third party app. would have any use for what
is in them. As such, I doubt it matters if they exist under /usr/include
or where they end up.

Do you have software that includes either of these files?

If so, I would like to hear whay that software is and why it includes
them. (Even bootstraps for diskless NFS root systems shouldn't need
what's in them, as far as I understand how it works.)
