+### Windows

+Running the `run-make` test suite on Windows is a bit more involved. There are numerous
+prerequisites and environmental requirements:

+- Install msys2: <https://www.msys2.org/>
+- Specify `MSYS2_PATH_TYPE=inherit` in `msys2.ini` in the msys2 installation directory, run the
+  following with `MSYS2 MSYS`:
+  - `pacman -Syuu`
+  - `pacman -S make`
+  - `pacman -S diffutils`
+  - `pacman -S binutils`
+  - `./x test run-make` (`./x test tests/run-make` doesn't work)
