gcc error while installing asyncio backport trollius (Python 2.7.5 and Win7)

Question

I fail to install asyncio backport trollius. From the docs, I have to: "...first build the _overlapped.pyd extension (it will be placed in the asyncio directory):"

Undeclared variables and type name. I know little C, what did I miss here?

you can install Microsoft SDK to build Python extensions, see: http://haypo-notes.readthedocs.org/misc.html#compile-python-extensions-on-windows
