I don't really understand the rationale for why the errors are phrased the way they are, but I notice the C errors generally mention C99 and the C++ errors generally mention C++11. So, since I didn't have a rationale, I copied what is already there. I thought maybe GCC is just emitting the default standard choice for each language. Tom
