Can one use (large) fft's with --enable-64? From what I can see
fftw 3.2.x is needed (which is only alpha) for 64-bit planner

Octave can be built without fftw, with the included fftpack. It'll be
slower, but should work with 64-bit..

This was I while ago, but will building fftw with (gfortran)

FFLAGS = -fdefault-integer-8

work. Otherwise, will --enable-64 break all fft functions when Octave is build with fftw support?
