I also can't find anything... until someone else comes with a 
better answer, maybe you can do this:

Use the ```-H``` compiler flag to generate ```.di``` files.

Remove all the ```extern(C)``` decls in the .di files.

Rename the file extension from ```.di``` to ```.h```

Technically, it should work. Hopefully someone else knows better.
