Yeah, that would be better.

As far as cruft goes, I think that even this approach is suboptimal since we still end up including an empty `loff_t.h` header from the main include file -- which could be very surprising to someone browsing through that header. Ideally, I think we'd have some mechanism to completely omit the header file on other OSs. I don't know if that would be through entrypoints.txt, changes in hdrgen/yaml, or ...
