Suggest a better one, then.

We cannot just return incorrect results, which FFTPACK seems to produce, 
especially as this easily occurs in the size range where memory 
constraints would be important.

Moreover, single-precision FFT is a new feature in 0.8.x, so it probably 
does not have an exceedingly large number of users yet who rely on it.
