Sorry, my previous email with attachment bounced. Here goes.

I'm getting a substantial amount of failing tests on MSVC,
https://gist.github.com/1836766. I think most complex number tests are
failing because they cast
a struct of a certain type to itself like ((struct_A) my_struct_A),
which MSVC doesn't allow.

Some tests seem to fail because they can't be imported: "compiling (c)
and running numpy_parallel: ImportError: No module named

And then there is a huge number of permission errors: WindowsError:
[Error 5] Access is denied:
'c:\\Users\\mark\\cython\\BUILD\\compile\\cpp\\libc_math.pyd' . Maybe
something is broken in the test runner (or in my setup somehow)?
