Yes, the freetype case has already been solved through removing the trouble-making part of header (it wasn't actually ever used) which made the headers compatible. In the longer run, we need more tools for that. During the weekend I'll attempt to write an acceptably good header wrapping function. We may also want a simpler ignore/exclude option but not sure how to do it properly. Certainly I wouldn't want the function to dumbly ignore the whole file, esp. considering that its contents (and thus ABI-specific data) can change over time (versions). -- Best regards, Michał Górny
