That's not the original behaviour:

Python 3.2.2+ (3.2:9ef20fbd340f, Oct 15 2011, 21:22:07) 
[GCC 4.5.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> e = OSError(5)
>>> e.errno
>>> e.strerror
>>> str(e)
'5'


I don't mind making this particular compatibility-breaking change,
though.

Regards

Antoine.
