No, PYTHONCASEOK is not set.

I get the problem with right away in the python shell:

D:\dev\python>python

   DeprecationWarning)
 >>>
 >>> import os
 >>> 'PYTHONCASEOK' in os.environ
False
 >>>

I also tried it within PythonWin: same result.

I did not edit any of the files in the Python library.  It does the same 
on WinNT and Win2000 but i also tried it on a XP machine and the problem 
is not on the XP machine.  But the source is the same on the XP machine 
(the FCNTL.py and tempfile.py) and the NT and 2000 machines.

I am starting to wonder if the problem is caused by a package that was 
installed on one set of machines and not the other.

Thanks!
