Well, it's Microsoft's choice. But from a Python point of view, which C type a Python int maps to is of little relevance.

Fair

Moreover, the development version is 3.4, and in Python 3 the int type is a variable-length integer type (sys.maxint doesn't exist anymore). So this discussion is largely moot now. Good to know. Too bad there still are libraries not supporting Python 3. Thanks.
