Summary: This prefix was added in r333421, and it changed our dumper output to say things like "CVRegEAX" instead of just "EAX". That's a functional change that I'd rather avoid. I tested GCC, Clang, and MSVC, and all of them support #pragma push_macro. They don't issue warnings whem the macro is not defined either. I don't have a Mac so I can't test the real termios.h header, but I looked at the termios.h sources online and looked for other conflicts. I saw only the CR* macros, so those are the ones we work around.
