And this exposes users to real bugs in their own code. :-( You can disable specific warnings when including headers that are known to be buggy but you can't upgrade. For your compiler explorer demo: #pragma GCC diagnostic push #pragma GCC diagnostic ignored "-Wuninitialized" #include <stuff.h> #pragma GCC diagnostic pop This is more targeted than "it's a system header, so ignore all its bugs".
