confusing diagnostics

[Ulrich Lauther <ulrich dot lauther at mchp dot siemens dot de>]

This (syntactically wrong) code gives rather confusing error reports:

class foo {
  int fudge;
  public:
  foo(int x) : fudge(x) {
  }
  virtual void do_something();
};

class bar : public foo {
public:
  bar(int x) : foo(x) {
  }
  void do_something() {
  }
};

int main() {
  bar(0);
  return 0;
}
