I think this is bug in Python distutils/msvccompiler.py.
Let me know if defining these variables work, then we can implement a 
workaround or show more informative messages on failure.

Note that one may get such an error only on AMD64 platform, the MSVC 
compiler uses other code on Intel machines and that works automagically
