I use -Weverything and turn off two warnings by pragma, which are -Wpadded, the one that generated your last warning, and -Wc++98-compat because I use `alignof()`. The pragmas may not be portable, but that doesn't matter in this specific case. I surround them with the equivalent of: #ifdef __clang__ #pragma clang ... #endif // __clang__ It works fine. Also, I like the style where declarations come first, so I leave that warning on. It's actually useful to me. (Probably not to anyone else, though.)
