None of these resulted in build bustage using our default configuration,
but apparently ccache builds were broken due to a bytes/text issue. Wish
the original reporter had mentioned he was using ccache, but he saved me
a lot of busywork. Changes appear safe across whole range of Python
versions we support.
Python no longer provides any version-related utilities in stdlib.
Did a thorough grep and made absolutely sure to replace every last
use. This was the work I was avoiding during my first port...
