- `-Wmissing-prototypes` and `-Wmissing-variable-declarations` are helpful for finding dead code and/or things that should be `static` but aren't marked as such. - `-Wunused-macros` is of similar utility, but for identifying dead macros. - `-Wunreachable-code` and `-Wunreachable-code-aggressive` do exactly what they say: flag unreachable code.
