According to the long list of issues, I don't think that it's possible
to compile and use Python stdlib when Python is compiled without
Unicode support. So I'm not sure that we can say that it's an
backward-incompatible change.

Who is somebody? Who compiles Python without Unicode support? Which
version of Python?

With Python 2.6, ./configure --disable-unicode fails with:
"checking what type to use for unicode... configure: error: invalid
value for --enable-unicode. Use either ucs2 or ucs4 (lowercase)."

So I'm not sure that anyone used this option recently.

The configure script was fixed 2 years ago in Python 2.7 (2 years
after the release of Python 2.7.0):
http://hg.python.org/cpython/rev/d7aff4423172
http://bugs.python.org/issue21833

"./configure --disable-unicode" works on Python 2.5.6: unicode type
doesn't exist, and u'abc' is a bytes string.

It works with Python 2.7.7+ too.
