WindowsError is an important distinction because its error codes are  
to be interepreted as being from Microsoft's windows error code list.  
That is a useful meaning. PlatformError is completely meaningless.  
Whether or not Python should really be raising errors with error  
numbers from the MS error number list instead of translating them to  
standard error codes is another issue...but as long as it does so, it  
should do so using WindowsError.
