The change to request the module went in after the 0.10.0 release, so
the 0.10.0 tarball is broken in this regard.

I think the difference here is that the Augeas 0.10.0 tarball only
contains the modules we request and build into it.  Since strchrnul
wasn't in the list, it wasn't shipped.

The bug was marked as a dupe because I'd already fixed the issue in git
(0d8d888) after the 0.10.0 release and then somebody else ran into it
too.  Unfortunately we haven't had a release since then to get the fixed
gnulib setup out.

Yes, that was a bit messy... I generated that patch by checking out
0.10.0 from git, adding strchrnul to the list of gnulib modules we
required and generating a new tarball from it.  Not ideal, but it got
the OpenCSW build going.
