I note that current numpy-vendor fails to cythonize in windows builds. Cython is installed, but I assume it needs to also be installed in each of the python versions in wine. Because the need to cythonize was already present in 1.9, I assume that the problem has been solved but the solution is not present in numpy-vendor in the numpy repos.

It's easy to work around by running cythonize in the Linux env you're using numpy-vendor in, then the files don't need to be generated in the Windows build. I think I've done that before. You only need one Windows Cython installed if the "cython" script is found. If not, you go to this except clause which indeed needs a Cython for every Python version: https://github.com/numpy/numpy/commit/dd220014373f A change similar to the f2py fix in https://github.com/numpy/numpy/commit/dd220014373f will likely fix it.
