It wouldn't hurt, since so many tests are failing, to do at least step
a., and maybe step b., too.

All the failures seem to have the same symptom: the symbol
PyUnicodeUCS2_AsWideChar can't be found.  In turn, I'm betting that's
because the Python you're actually running was built with a different
Py_UNICODE_SIZE or Py_UNICODE_WIDE setting than the setting in your
Python.h.

Unfortunately failed "run" test results no longer show the invocation
command, so it's hard to get all the info I'd like in order to debug
this.
