That's not right, it merely has to have a mode in which it operates in a strictly standard manner. There is nothing in the C standard that prevents a compiler from having options for non-standard behavior. GNU C already has non-standard extensions, this would just be another case where, by setting certain options, you get non-standard behavior.
