Details:

We're seeing build issues with plplot against octave 3.8.0:

 # error "The file <octave/config.h> must be included before oct-refcount.h."

This appears to be because plplot's own config.h is included from octave/oct.h
instead of octave's.  octave/oct.h has:

#include <config.h>

I would argue that this should be <octave/config.h> (and same for other octave
headers).
