Dan,
The problem seems to be that not all #defines are captured in the new
"features" keyword. The definition for HAVE_FFTW is in configure.ac in the
AH_BOTTOM macro which means it is copied to the bottom of config.h.
/* Octave is currently unable to use FFTW unless both float
and double versions are available. */
#if defined (HAVE_FFTW3) && defined (HAVE_FFTW3F)
#define HAVE_FFTW
#endif
I wasn't following closely what jwe did when he added the "features"
keyword, but hopefully it is simple to fix.
