Now I'm confused, because AFAICT, that's the only place the 
compiler will give you that error. Yet you get that error message 
in D code:

Does that mean everything is treated as ImportC? If so, it 
shouldn't:

```
     // For ImportC
     bool Ccompile;              /// true if compiling ImportC
```
