errno 22 instead of errno 2

open("c:\abc","rb") This simple one-line script, produces errno 22 on Python 2.6, but errno 2 on Python 2.5.2 Is this an unintentional regression? Or is this an intentional bug fix? The file doesn't exist (errno 2) but I guess on Windows it is also somewhat an invalid file name (errno 22).
