[Zhaojun-Liu]

Hi all,
Recently, we update the commit of annoy and it failed to run test on Windows, could you please take a look at this issue? Thanks.

Repro steps:

1. git clone https://github.com/spotify/annoy F:\gitP\spotify\annoy
2. git -C "F:\gitP\spotify\annoy" reset --hard 7595fb3
3. python.exe -m pip install numpy h5py pytest
4. python setup.py build
5. python setup.py nosetests

Actual:
