Dear Gromacs developers,

both, src/mdlib/gmx_fft_fftw2.c and src/mdlib/gmx_fft_fftw3.c
define a symbol "gmx_fft_fftw2_empty" at the very end of the file.
If you try to configure with --with-fft=mkl this causes a fatal
error during compilation due to multiple definition of

I assume that it should read "gmx_fft_fftwr3_empty" in
src/mdlib/gmx_fft_fftw3.c. See also the attached patch.

Best regards,
