It should be noted that function pointer comparison is defined to not be deterministic between different compiler option sets, it's at least for now possible but mostly useless. Through there are bugs involved, too ;=) (Due to const folding comparisons vs. doing them at runtime there was/is non-determinism in the same build between different call sites ... )
