You update the compiler and suddenly the same code now generates warnings. Are these old warnings or new warnings? I have seen that with printing an integer in a loop 0..99. Old compilers didn't understand the limit so warned that my buffer was not big enough. Middle aged compilers were silent because I assume they understood the range. New compilers started warning again that the range was -2147483648..99 dumb shits. Or are you one of those to never update a working system, which I completely agree with.
