Installing fftw--Unable to guess build type

I'm trying to install FFTW and when I get to the ./configure --enable-mpi --enable-type-prefix --enable-float command and when I run it, this is the error I get. How do I overcome this? I'm in Cygwin on windows 10 if that helps.

fftw-2.1.5 is so old that it requires a suggestion to properly configure under a recent Cygwin.

$ ./configure --enable-mpi --enable-type-prefix --enable-float  --build=x86_64-pc-cygwin

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... gawk
checking whether make sets $(MAKE)... yes
....
config.status: creating mpi/Makefile
config.status: creating fftw.spec
config.status: creating fftw/config.h
config.status: creating fftw/fftw.h
config.status: executing depfiles commands

I will not bet that you will have clean run with MPI and HDF5 as they also are more recent than those tested on Gadget2
