[cfe-dev] CXXRecordDecl Name

[Daniel Dilts]

If I have this code then everything works.  If I get rid of the forward
declaration, then any method returns an empty string.  Is the forward
declaration mandatory when defining the class like this?

namespace N {
  class BaseClass1;
}
class N::BaseClass1 {
public:
  BaseClass1(int i);
  BaseClass1(const BaseClass1 &right);
  virtual ~BaseClass1();
  BaseClass1 &operator=(const BaseClass1 &right);
}
