My concern is that once we have a mechanism to suppress warnings in system
header files, the quality of glibc and libstdc++ will start to degrade ...
it will be too easy to just turn off warnings rather than to code things
correctly (and if avoiding a warning makes your code worse, the warning
is poorly designed or implemented).
