--- Comment #3 from Segher Boessenkool <segher at gcc dot gnu.org> ---
Casting between incompatible function types is explicitly allowed, both
in C and in C++.  And many programs actually do this.  Only actually
*calling* a function via the wrong type is UB.

You probably get too many warnings for -Wextra, and certainly for -Wall.
"-Wbad-*" is a terrible name in any case (there is nothing bad about such
a cast).
