In case of windows, python scripts are executed and I think it runs fine from cygwin. Is this change targeted to make it work from cmd?

My test environment is on Windows 2008 & cygwin 64 bits version .

I can reoccur the error's by below python scripts:

--------------------------- cygwin_python_test.py -------------------
import os.path
import sys
file_name = sys.argv[1]
if os.path.exists(file_name):
print file_name
else:
print "can not find"
-------------------------------- end --------------------------

test it by , touch a file : F:/sourcecode/python/a-exist.txt

First test with Backslash :
$ python cygwin_python_test.py F:\sourcecode\python\a-exist.txt
can not find

Then with slash :

$ python cygwin_python_test.py F:/sourcecode/python/a-exist.txt
F:/sourcecode/python/a-exist.txt

So , I thinks we should change the backslash to slash in windows environment .

Thanks for the patch. Agree to the slash change. I am pushing this to master(4.6). Let me know if you want it on any other branch.
