Fails to build with Visual Studio 2010

[emmatyping]

I was working on appveyor builds of mypy, and when I initially tested Python 3.3 and 3.4, which use the older Visual Studio 2010 compiler, compilation failed. It'd be great if typed_ast were to compile for Python 3.3 and 3.4 on Windows

here is the log:

For now, typed_ast only supports Windows for Python 3.5+, and there are no concrete plans to change this.

[emmatyping]

No problem. Just wanted to share that it is an issue.

[ddfisher]

Closing as wontfix.

@ethanhs For your information: I'm working with Python 3.4 under Windows (WinPython-32bit-3.4.4.5Qt5). Mingwpy (my version: 0.1.0b3) is able to compile type_ast.

@pa-eidam, thanks, I was mostly just testing, but thanks for sharing a possible workaround

[emmatyping]

This was fixed in #47 (for anyone chancing upon this).
