Hi Orion:
Thanks for doing that suggested experiment. More below
in context.

"is_real_nd_array" is only used in a function that is provided by swig
(as opposed to C++ interface code supplied by PLplot). So I would
summarize this issue as a backwards-incompatible Octave change (or
bug) that is confounding swig very similar to the missing
OCTAVE_API_VERSION_NUMBER #define.
Again, I think the Octave developers should be consulted about this to
see whether this is a bug or an intended backwards-incompatible change
in the Octave C++ library API.
I won't comment on the rest of the compiler messages you listed since they all
appear to be compiler warning messages as opposed to the much more
serious compiler error message above that breaks our build.
I have finally found the release notes for octave-3.8.0 at
<http://www.gnu.org/software/octave/NEWS-3.8.html> which list some of
the new features and backwards incompatible changes. I think most/all
of those are relevant only for octave source code and not for the
octave C++ library. Nevertheless I mention that URL because that
document may be a good guide to any changes we may have to make in our
octave-level source code if/when we find a way to get the
swig-generated octave bindings built for Octave version 3.8.x.
