pip installation of zfpy on Windows 10 using MSYS2 MinGW 64-bit fails

I'm using MSYS2 and trying to install zfpy from the MinGW 64-bit console, using Python3, and pip installed from the `mingw-w64-x86_64-python-pip` package.

To recreate this, one should be able to:

- install MSYS2
- open the "MSYS2 MinGW 64-bit" console
- run `pacman -Sy mingw-w64-x86_64-python mingw-w64-x86_64-python-pip`
- run `pip install zfpy`

Here's the output with failure message:

```

Happy to try to help debug this.

Start by reproducing the installation with the listed MSYS2, pacman, and pip commands, then inspect setup.py and the referenced build/python/zfpy.c path shown in the compiler output. Done means pip install zfpy completes successfully in the MSYS2 MinGW 64-bit Python 3 environment.
