A quick note regarding sse/sse2 with gcc -

"With SSE/SSE2 and gcc, you should use a version of gcc that properly
aligns the stack when compiling any code that links to FFTW. By default,
gcc 2.95 and later versions align the stack as needed, but you should
not use the -Os option or the -mpreferred-stack-boundary option with an
argument less than 4."
