#156 Compilation/Syntax error on Windows 10 when installing via pip

[Z Feuerborn]

Installing via pip, I get the following error on windows? pip is trying to install the latest 0.6.3 version. The command I am running to install it is:

PS C:> python.exe -m pip install RPi.GPIO

PS C:\> python.exe -m pip install RPi.GPIO

Disclaimer, I am new to both Python and Pi development, so this might just be a PEBCAK.

My main goal is to just get the library installed for PyCharm to pick it up to autompletion, so I am under no illusions that I will get this to actually run under my normal dev box.
