That's the VC linker telling you that rfftw_* functions aren't exported
in the fftw libs on Win32 (they are on Unix).  As I'm not a windows guy,
I'm not sure of the "right" fix, but this will get it to work:

Edit rfftw/rfftw.h, find the prototypes for rfftw_one, rfftw_create_plan,
and rfftw_destroy_plan. 

For each prototype (e.g. extern void foo()), rewrite them thus:
extern _declspec(dllexport) void foo();

Rebuild the fftw libs and that should take care of it.
