In PR #37300, Alexej asked why we the compiler does not warn about unnecessary semicolons, e.g. f() { }; // <-- here The answer is surprising: In C++98, above syntax was disallowed but by most compilers accepted it regardless. C++>11 introduced "empty declarations" which made the syntax legal. The previous behavior can be restored using flag -Wc++98-compat-extra-semi. This finds many useless semicolons which were removed in this change. Unfortunately, there are also false positives which would require #pragma-s and HAS_* logic (--> check_flags.cmake) to suppress. In the end, -Wc++98-compat-extra-semi comes with extra effort for little benefit. Therefore, this change only fixes some semicolons but does not enable the flag.
