\ FFT compilation controls.
\ Change true/false flag on left to set control on the right.
\ Logic is present to preclude invalid combinations of settings.
\ This is mainly a convenience to allow changing a parameter like
\ float_fft? without having to manually change other paramters to
\ be consistant.  Some options are only available with floating
\ point and other options are only available with fixed point versions.
