I know that /dev is a bad name (in my case on Windows its the directory 
for development, not device).  The  but i have a set of pathon scripts 
under development.  The PYTHONPATH environment variable is set to make 
sure that it looks into it.  If i remove d:/dev/python from the 
PYTHONPATH and import tempfile i get the same results.

C:\Python23\Lib>set PYTHONPATH=

C:\Python23\Lib>python

I did that. Helped solve the problem:  fcntl.pyc was present and that 
was causing the problem!

Before deleting fcntl.pyc:

python -vv
....
....

 >>> import tempfile
# trying tempfile.pyd
# trying tempfile.dll
# trying tempfile.py
# tempfile.pyc matches tempfile.py
import tempfile # precompiled from tempfile.pyc
import errno # builtin
# trying random.pyd
# trying random.dll
# trying random.py
# random.pyc matches random.py
import random # precompiled from random.pyc
import math # builtin
import _random # builtin
import time # builtin
# trying fcntl.pyd
# trying fcntl.dll
# trying fcntl.py
# trying fcntl.pyw
# trying fcntl.pyc
import fcntl # precompiled from fcntl.pyc
fcntl.py:7: DeprecationWarning: the FCNTL module is deprecated; please 
use fcntl
   DeprecationWarning)
import thread # builtin

Then I deleted fcntl.pyc:

C:\Python23\Lib>del fcntl.pyc

C:\Python23\Lib>python
Python 2.3.1 (#47, Sep 23 2003, 23:47:32) [MSC v.1200 32 bit (Intel)] on 
win32
Type "help", "copyright", "credits" or "license" for more information.
 >>> import tempfile
 >>>

The problem is SOLVED!
^^^^^^^^^^^^^^^^^^^^^^

Now, I looked at the C/Python23/Lib files before deleting fcntl.pyc and 
this is what i had:

C:\Python23\Lib>lt -l [fF]*.py*
-rwxrwxrwa   1 Administrators  None     4709 Jan 21  2001 fpformat.py
-rwxrwxrwa   1 Administrators  None      418 May  9  2001 FCNTL.py
-rwxrwxrwa   1 Administrators  None    27589 Jun  3  2002 ftplib.py
-rwxrwxrwa   1 Administrators  None    12732 Jan  8  2003 fileinput.py
-rwxrwxrwa   1 Administrators  None    15548 Feb 27  2003 formatter.py
-rwxrwxrwa   1 Administrators  None     3126 Jul 13 18:06 fnmatch.py
-rwxrwxrwa   1 Administrators  None    10173 Sep  2 07:47 filecmp.py
-rwxrwxrwa   1 Administrators  None     3637 Sep 29 12:01 fnmatch.pyc
-rwxrwxrwa   1 Administrators  None    11652 Sep 29 12:01 filecmp.pyc
-rwxrwxrwa   1 Administrators  None      583 Sep 30 10:28 fcntl.pyc


What is strange is that it seems that the import of FCNTL.py is case 
insensitive, where my system does not make it case insensitive (i dont 
have PYTHONCASEOK set).

So, the problem got solved by deleting the fcntl.pyc.  I don't really 
understand why it solved the problem unless the .pyc was from an old 
version (however when i installed Python 2.3 and 2.3.1, I created a new 
directory).

Tim and Michael, Thanks for your help!
