Spoke too soon.  (Geez. I feel like a finicky old schoolmarm...)

  fftw3
  libfftw3_3
  libfftw3-devel

(that is, no '_3' DLL-number decorator for the -devel package)

The pattern for package 'foo' that provides the DLL cygmyfroboz-7.dll is 
usually

   foo-${VER}-${REL}.tar.bz2
   foo-${VER}-${REL}-src.tar.bz2
   libmyfroboz7-${VER}-${REL}.tar.bz2
   libmyfroboz-devel-${VER}-${REL}.tar.bz2
   (sometimes foo-devel, but not recommended).

However, when 'myfroboz' itself ends with a number (like bzip2: 
cygbz2-1.dll), then the pattern is the same except for the one that 
provides the DLL. So, if we had cygmyfroboz1-7.dll, then:

    libmyfroboz1_7-${VER}-${REL}.tar.bz2

So, in your case,
   foo == 'fftw3'
   DLL == cygfftw3-3.dll

So,

   fftw3-${VER}-${REL}.tar.bz2
   fftw3-${VER}-${REL}-src.tar.bz2
   libfftw3_3-${VER}-${REL}.tar.bz2
   libfftw3-devel-${VER}-${REL}.tar.bz2
   (e.g. no '_3' decorator on the -devel package)

Ex. bzip2:

   bzip2-1.0.5-2.tar.bz2
   bzip2-1.0.5-2-src.tar.bz2
   libbz2_1-1.0.5-2.tar.bz2     (cygbz2-1.dll)
   libbz2-devel-1.0.5-2.tar.bz2
