--- Comment #1 from Harald van Dijk <harald at gigawatt dot nl> ---
This may be in order to ensure that the following valid C++03 code is accepted
in C++11 mode as well, to limit the impact when the default language version
was changed:

  struct A {
    explicit A(int = 24);
  };
  int main() {
    A a[1] = {};
  }

This did not get diagnosed in GCC 5 in any mode. GCC 6 accepts it without a
warning in C++03 mode, and accepts it with a warning in C++11 mode.
