Btw, a lot of bad things are already present as compile time warnings. Using -Wall -Werror (or similar) should already the default for new projects for well over a decade. You probably know that, but "stealing" stuff from there is also a good idea. Plus, iirc, there are several additional warning options that are not contained in -Wall. Maybe you want to add some of these, too.
