winfo_pathname gives an exception on 64-bit Python on Microsoft Windows.

The script below shows the exception for 64-bit Python, and runs without
exception on 32-bit Python.

Both 64-bit and 32-bit wish86, compiled from source by 'Command Prompt
for VS 2017', runs are fine.

Reading 'winfo pathname' entry in the Tk man page for winfo makes me think
'... does not give an exception on 32-bit ...' may be a better title for
this issue.  However I like to think the 'winfo pathname' entry is poorly
drafted: which implies a problem in tkinter for the 64-bit version.

The winfo_name and winfo_parent methods provide a workaround to get the
pathname, so the problem is not as serious as not being warned it exists.
