Some more info:

swig currently defines:

namespace Swig {

  class octave_swig_ref:public octave_base_value {
...
  private:
    DECLARE_OCTAVE_ALLOCATOR;
    DECLARE_OV_TYPEID_FUNCTIONS_AND_DATA;
  };
  DEFINE_OCTAVE_ALLOCATOR(octave_swig_ref);
  DEFINE_OV_TYPEID_FUNCTIONS_AND_DATA(octave_swig_ref, "swig_ref", "swig_ref");

So I see that the *_OCTAVE_ALLOCATOR defines are gone, so I removed the from
the above.  But I suspect we aren't registering the swig_ref type properly
leading to the error:

 error: octave_base_value::print (): wrong type argument 'swig_ref'

I see that there is a DECLARE_OV_TYPEID_FUNCTIONS_AND_DATA2() macro now.  Does
that need to be used?

Again any help would be greatly appreciated.
