--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
Flags -Werror=3Dimplicit-int and -Werror=3Dold-style-definition seem useful.

Here is another reduced test case:

int a, b, d;
char c, e;
void f(void) {
  char g =3D c;
  if (b)
    goto h;
  while (d) {
    e =3D c;
  h:
    d -=3D a;
  }
}=
