Win32com (Python 3.8): identity versus equality comparison

[josephsl]

Hi,

Follow-up from nvaccess/nvda:10977:

When running scons launcher/dist from Python 3.8, syntax warning is printed for an identity comparison in win32com/client/makepy.py line 369. Specifically:

if path is not '' and not os.path.exists(path):

I expect this would have been fixed in win32com upstream, but won't hurt to make sure this is reported, as Py2exe still relies on win32com for certain operations.

Thanks.
