[Numpy-discussion] Compiling NumPy on Windows for Python 3.3 with MSVC 2010

[Peter Cock]

Changing title to reflect the fact this thread is now about using
the Microsoft compiler rather than mingw32 as in the old thread.

I would have tried this earlier, but it required Windows XP SP3
and there was something amiss with the permissions on my
work Windows machine preventing that update. Solved now,
and this file now exists:

C:\Program Files\Microsoft Visual Studio 10.0\VC\vcvarsall.bat

I've tried my branch (focussed on mingw32 fixes), and numpy-1.7.0b2
but both fail at the same point. I did remove the old build directory first.

It appears a similar issue was raised before:

Any tips?
