I took a brief look at it, and from the errors I have seen, one is
cosmetic, the other one is a bit more involved (rewriting
PyArray_Scalar unicode support). While it is not difficult in nature,
the current code has multiple #ifdef of Py_UNICODE_WIDE, meaning it
would require multiple configurations on multiple python versions to
be tested.

I don't think python 3.3 support is critical - people who want to play
with bet interpreters can build numpy by themselves from master, so I
am -1 on integrating this into 1.7.

I may have a fix within tonight for it, though,
