Multi-threaded DLL (/MD) runtime environment.
+If you wish to override this detection method to use a different compiler
+(mingw or a different version of MSVC):

+* set up the PATH and other environment variables as needed
+* set the `CC` environment variable to compiler exe to be used,

**Note:** PyPy is currently not supported for 64 bit Python, and translation
will fail in this case.

Since hacking on PyPy means running tests, you will need a way to specify
the mingw compiler when hacking (as opposed to translating). As of
March 2012, --cc is not a valid option for pytest.py. However if you set an
-environment variable CC to the compliter exe, testing will use it.
