I haven't had any problems with the files, except there could be a file conflict on a case-insensitive system.
The SRC_lapw0/Makefile does not use the object file zfft3d.o (it's commented out). So it shouldn't matter if you keep or remove both files (zfft3d.f and zfft3d.F). I believe the files were replaced by the new fft module (fft_modules.F and and fftpack_helpers.f).
