OSError on MinGW64 with MSYS2 on Windows 8.1

[victorliu]

A most basic script containing:

import click
click.echo('run')

Produces the following stacktrace:

Traceback (most recent call last):
  File "t.py", line 3, in <module>
    click.echo('run')

OSError: Windows error 1

I am running under a MinGW64 bash shell installed through MSYS2 on a Windows 8.1 machine.
This is with Python 3.7, colorama 0.4.1, and Click 7.0, but the error goes back to 6.0, whereas it does not occur on 5.1. Python 2 does not exhibit the error.

None of MinGW, MSYS2, or Windows 8.1 are officially supported, but I'll leave this open for a while in case someone sees something.

I can reproduce this issue with MSYS2 in Windows 10 when trying to use black which depends on click.

@davidism, is this fixed in master but not released yet?
