Comment (by cdavid):

 Is this still useful to keep this ticket opened ? fftw3 has support for
 SIMD, and does this more or less transparently. I did a few benchmarks
 sometimes ago, and doing SIMD is not really useful except if always use
 SIMD (eg a caching which tests whether the data are 16 byte aligned and
 using corresponding cached plans is not helpful), and this on a P4, where
 SIMD is supposed to matter the most.

 I could rework on the patch against recent svn if you are interested,
 though.
