Hmm.  I don't see this problem on my system (Debian GNU/Linux) but I
made the following change anyway (I think NULL should probably be
avoided in C++ code).

	* oct-fftw.cc (octave_fftw::fft2d): Avoid having to find a
	definition for NULL by passing 0 as the last arg to fftwnd_one.
	(octave_fftw::ifft2d): Likewise.
