Probably it's a issue with Windows Python version?
Also my Python 2.5 sometimes try to report localized error messages
(i.e. russian for my russian win32) instead of english ones.

Thanks for the hint. I was unaware about this function.
It works fine with Python 2.5 and returns expected english messages.
But I'm worry about this comment in python doc:

strerror( code)
	Return the error message corresponding to the error code in code. Availability: Unix, Windows.


This function does not exist on Mac? In this case I'm better to keep
my dictionary with error messages.
