No, because SIMD optimizations are broken. I've been unable to compile
version which is able to run on all >=i686 platforms and includes 3DNow
&/ SSE stuff. It just crashed on my Thunderbird-core Athlon.

I use *_execute_dft_r2c().

Also SIMD optimizations doesn't do any good on non-x86 architectures
like SPARC, Alpha or HP-PA.

Anyway, I'm going to add some SIMD stuff to Ooura also.
