I work on a project with a large code base some of which is pretty old. We are discussing adding -std=gnu++11 to our g++ compiles to be able to use newer classes/features but there are concerns that there could be unintended consequences. For existing code that doesn't use any new features/classes can it be expected that its function will not be altered by use of this flag? Will we have to regression all of our c++ code?
