WinAppDbg fails in Python 2.3 when trying to get the winerror property of WindowsError

[qvasimodo]

The WindowsError exception class has a property named "winerror", which contains the Win32 error code, as opposed to "errno" which contains the error code translated by msvcrt.

However in Python 2.3 and older, WindowsError contained the Win32 API error code in errno, and winerror didn't exist. This causes WinAppDbg to fail in some cases, particularly when trying to enumerate processes, threads and modules.
