os.path.normpath() on WIN32 systems returns a null 
string for . followed by a directory separator:

>>> os.path.normpath('./')
''
>>> os.path.normpath('.\\')
''
>>> os.path.normpath('.')
'.'
>>>

Contrast with what happens on Linux:

>>> os.path.normpath('./')
'.'
>>> os.path.normpath('.')
'.'
>>>

Sorry, I don't have a later version than 2.1.1 
available to check whether this is fixed in a later 
version, but I did do a search for other reports of 
this bug and found none.

This appears to be fixed in 2.3b1:

It seems that this has been fixed in ntpath.py rev 1.41:
$ cvs up -r 1.41 Lib/ntpath.py
P Lib/ntpath.py
$ ./pcbuild/python
Python 2.3b1+ (#40, Jun 16 2003, 18:55:59) [MSC v.1200 32
bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more
information.
>>> import ntpath
>>> ntpath.normpath(".")
'.'
>>> ntpath.normpath("./")
'.'
>>> ntpath.normpath(".\\")
'.'
>>>

$ cvs up -r 1.40 Lib/ntpath.py
P Lib/ntpath.py
$ ./pcbuild/python
Python 2.3b1+ (#40, Jun 16 2003, 18:55:59) [MSC v.1200 32

>>> import ntpath
>>> ntpath.normpath(".")
'.'
>>> ntpath.normpath("./")
''
>>> ntpath.normpath(".\\")
''

rev 1.41 was part of Python 2.2, so I think we can close
this bug.
