This might be a problem with cbindgen. I tried to make a minimal case
for it and it would fail even on a linux machine.

It is uintptr_t mBits, which should translate to usize, but gets
translated to u64.

Not 100% sure about this though.

I'm trying to use cbindgen as a standalone but it's been tricky.
