We found a few multiple definitions errors in WPILib so we fixed them. Right now the major fix is the error with multiple definitions in SimpleCRobot.h and CDriverStation.h, so this really applies only to teams using C. To use the library, just make a new project and add all these files, compile it, and then run the updateBuiltInLibrary.cmd script in \WPILib\Scripts
