- AlotOfReading 2y agoNot a perfect defense either. If you ever have the misfortune of using mentor graphics code, they #define REGISTER. They also ship a standard library that uses the register keyword. If you build a project using their standard library and their toolchain together, it explodes. If you name something like set_register, it also explodes.
