FFTW implements runtime detection of sse2 and avx. You can produce a combined
sse2/avx binary that will run anywhere, including pre-sse machines. The
windows binaries on fftw.org have this property.
The --enable-sse flag tells FFTW that your compiler supports SSE. The compiler
is after all under no obligation to support x86 extensions, and by default FFTW
tries to require only C89 support.
