 # `sh.exe --login` sets a couple of extra environment variables that are defined
 # in the MinGW shell, but switches CWD to /home/$username.  The previous value
 # is stored in OLDPWD.  Of the added variables, MSYSTEM is crucial to running
 # run-tests.py- it is needed to make run-tests.py generate a `python3` script
 # that satisfies the various shebang lines and delegates to `py -3`.
