We could also change Octave so that we have something like

  #if ! defined (OCTAVE_DEPRECATED)
     ... current definition ...
  #endif

and then you could just define away OCTAVE_DEPRECATED(msg) to avoid the 
warnings.

Or, I think you can just add the GCC option -Wno-deprecated-declarations 
to CXXFLAGS.
