Changes since v2.21:
- Updated libsndfile and FFTW.
- 2.22 compiled for Pentium III and below CPUs. Slightly faster even on Pentium M and 4.
- Removed residual SIMD code that led to "Unexpected exception" notifications on non-Pentium 4 cpus. Thanks to Simon George for fix.
- Accept raw 64-bit float format filter files (.dbl) (Internal processing is still 32-bit.).
