title: Compiling Python modules on Windows x64
body: <p>I'm starting out some projects in words processing and I needed NumPy and NLTK.
  That was the first time I got to know <code>easy_install</code> and how to compile new module of python into the system.</p>
  
  <p>I have Python 2.7 x64 plus VS 11 and VS 12. Also Cygwin (the latest one I guess).
  I could see in the file that compiles using VS that it looks for VS env with the same version as the one that compiled the python code, why?
  When I hardcoded 11.0 which is my version, numpy failed to build on several strange errors regarding <code>vcvarsall</code> (it found <code>vcvarsall</code>, probably misused it).</p>
  
  <p>Can't I build python binaries on Windows?
  If not, can I cross compile on Linux for Windows? (using the same method as Google for the Android SDK)</p>
