Incompatibility between Python 2.7.11 and Vim 64 bits on Windows

[micbou]

Description

I am using my own built version of Vim 64 bits for Windows with python2 support and I am getting the following error when running python2 inside Vim

E887: Sorry, this command is disabled, the Python's site module could not be loaded.

with python 2.7.11 64 bits. I don't have this issue with the previous version (2.7.10) of Python.

How to reproduce

Install Vim 7.4.972 64 bits for Windows and python 2.7.11 64 bits on Windows 7 64 bits.
Start Vim:

vim -N -u NONE

and run the command:

:py 1

Configuration details

In a shell:

$ python

In Vim:

:echo has('python')

I can confirm that this is specific to the python 64 bits version. It works fine with Vim 32 bits and python 2.7.11 32 bits. Maybe it should be reported to the python folks?

[k-takata]

Maybe same as #526?
