Yes it is correct that for amd64 SSE is enabled by default in the compiler. But (if I'm not wrong) the FFTW --enable-sse flag does not (only) set compiler flags. Instead it activates the specially written SSE optimized kernels are compiled. Because the --enable-sse flag is not passed, those kernels are not compiled even though all amd64 processors have SSE/SSE2. Thus SSE is activated in the compiler but not for FFTW.
