I cannot believe, that this is a bug, but I did not find any explanation for
this behaviour. When I compile following simple class, I get an error:
class Ct {
public:
int __ct;
Ct() : __ct(0) {};
};
int main() {
Ct ctobj;
}

Identifiers which have two underscores in front of them are reserved for the compiler so this is
invalid.

While Andrew is right that you must not use names that start with
two underscores, the error message we give is really not very
helpful. I also don't know where it comes from: it is certainly not
the preprocessor that is replacing the token by something else, and
the compiler does not complain about the declaration of the field,
only about its use. We should be able to do better here.

Fixed by accepting it in 4.0.0. What changed was the name of the constructor internally was renamed
to " __ct".
