   Using os.path.realpath(...) in the MVFS of Clearcase SCM (virtual file system) in Windows 10 a exception occures:

   X:\my_view\tools\python\3_8>python.exe
   Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:57:54) [MSC v.1924 64 bit (AMD64)] on win32
   Type "help", "copyright", "credits" or "license" for more information.
   >>> import os
   >>> os.path.realpath('.')
   Traceback (most recent call last):
     File "X:\my_view\tools\python\3_8\lib\ntpath.py", line 647, in realpath
       path = _getfinalpathname(path)
   OSError: [WinError 87] Falscher Parameter: 'X:\\my_view\\tools\\python\\3_8\\.'
   
   During handling of the above exception, another exception occurred:
   
   Traceback (most recent call last):
     File "<stdin>", line 1, in <module>
     File "X:\my_view\tools\python\3_8\lib\ntpath.py", line 651, in realpath
       path = _getfinalpathname_nonstrict(path)
     File "X:\my_view\tools\python\3_8\lib\ntpath.py", line 601, in _getfinalpathname_nonstrict
       path = _getfinalpathname(path)
   FileNotFoundError: [WinError 161] Der angegebene Pfadname ist ungültig: 'X:\\'
   >>> 

   The error 161 (ERROR_BAD_PATHNAME) should also be ignored in _getfinalpathname_nonstrict.
