I'm confused. Since C++ treats the lack of a prototype as a hard error, what does it mean to make -Wmissing-prototypes useless?

-Wmissing-prototype looks very similar to -Wmissing-declarations (which is supported in C++ but documented as C/objC only). It requires that you first have:

int f(int);
and only then:
int f(int){return 0;}
