I think the build will just fail if no Fortran compiler is present.

Currently, our binaries are built using gfortran on Linux/OSX and
mingw-g77 on Windows. The problems with Fortran 90 come mainly on
Windows. It's AFAIK possible to set up a toolchain today based on
mingw-64 that can produce OK results with Gfortran without CRT issues,
but this does seem to require some nontrivial fiddling.

So at the moment, lack of out-of-the-box free toolchain for Fortran 90
on Windows is blocking inclusion of F90 code in Scipy.
