--- Comment #11 from Jan Kratochvil <jan.kratochvil at redhat dot com> ---
Similar inappropriate warning is generated for typedef-vs-variable as reported
now by Adam Jackson.  Again a mistaken use cannot harm as it causes other
errors.  And clang also does not warn on it.

int main(void) {
  typedef int x; 
  {
    int x = 0;
    return x;
  }
}
