I'm seeing:

    FFTW3 = 0
    FFTW3F = 0
    FFTW3F_THREADS = 0
    FFTW3_H = 0
    FFTW3_THREADS = 0

OK, I see what you are saying.  That line should read

***** testif HAVE_FFTW3

That is a generated line (fftw.cc-tst, not a script file), so I'll leave 
that one up to someone who is more adept with that step.
