Yes, the --enable-* options are implemented by the package, in my case it
tries to use the sse operations instead of the 387 ones. Its supposed
to be an improvement (at least on PIV).

Oops. Yes, that
a known problem, but I think the README file is a bit
misleading - its supposed to be hinting that you should build FFTW with
--enable-sse, not the plugins. gcc's automatic SSE support is not very
good (which is all it enables IIRC), and used to produce worse code.
so i can safely use --enable-sse with fftw, when it produces an internal
compiler error with swh-plugins???
