Redirecting it gcc@ since that is where this part should be taken.

PS. A separate question, of course, is whether gcc 4.0's C compiler
works with FFTW. The answer, at the moment, is "no" if you try to use
SSE/SSE2, thanks to the usual gcc bugs. I'm trying to isolate and
file bug reports for the problems, so hopefully the official release
will work.
There has been rewrite of the SSE/SSE2 support. Depending on how you
write the
code, if you wrote it using the intrinsics then the bug is in GCC.
