[Python-Dev] trunk doctests fail to execute with 2.7 alpha

[anatoly techtonik]

I can not compile Python itself, so I use Alpha version to run tests
in trunk. Recent update broke successfully running tests. Any hints
why this happened and how to fix them back?

> C:\~env\Python27\python.exe test\test_doctest.py

doctest (doctest) ... 66 tests with zero failures
