ImportC automatic preprocessor?

[Chris Piker via D.gnu]

Hi GDC

Over at: https://gcc.gnu.org/onlinedocs/gdc/Missing-Features.html 
I read that GDC doesn't invoke the preprocessor automatically:

```
ImportC Limitations

    GNU D does not run the preprocessor automatically for any 
ImportC sources. Instead all C files are expected to be manually 
preprocessed before they are imported into the compilation.
```

Is that a feature that is likely, or unlikely, to be added to a 
future version of GDC?

Thanks,
