The following program should not compile.

class C
{
  auto union  // bad
    {
      int a;
    };
  register union  // bad
    {
      int b;
    };
  static union  // bad
    {
      int c;
    };
  extern union  // bad
    {
      int d;
    };
  mutable union  // bad
    {
      int e;
    };
};

auto, register, and extern are not normally allowed in classes.

static and mutable might be allowed on other members, but not on anonymous
unions. See C++ standard clause 9.5/3.
