well, obviously that "shouldn't fail" since the same pathname component
is present in both versions.

There's now a mingw platform module - don't know if that existed in
3.0.0, would have to do some prospecting.  It defines
MINGW_DEFAULT_PATHS, which is a lot shorter than mingw_paths in the tool
module.  I wonder if that's in play somehow?

if sys.platform == 'win32':
    MINGW_DEFAULT_PATHS = [
        r'C:\msys64',
        r'C:\msys'
    ]
