Hi folks,
I'm trying to build numpy HEAD on Windows in preparation for the SciPy
sprints tomorrow. I've never built numpy on Windows, and I'm new to git,
so I could be doing any number of things wrong.
I think I have the latest code:

I tried to build it with a simple:
python setup.py build_ext --inplace
and got:

Python 2.7.2, python.org build (32 bit)
Visual Studio express 2008
That should work, yes?
Thanks for any hints.

Hi Chris,
the build should work but it is probably better to install numpy in the
site-packages directory (and be prepared for crashes and test failures).
A patch for the build issues is attached. Remove the build directory
before rebuilding.
