Actually it makes things worse because a varyadic function will never
match a non varyadic one:

main() {
    void (*a)(int, ...);
    void foo(int);

    a = foo;
}

% gcc foo.c
foo.c: In function `main':
foo.c:7: warning: assignment from incompatible pointer type
% cc foo.c
"foo.c", line 7: warning: assignment type mismatch:
	pointer to function(int, ...) returning void "=" pointer to function(int) returning void
