You inferred correctly, we don't need the types to be a particular size, I just need to be cognizant of when they change size because it impacts syn's performance. And for that purpose, I personally only care about 64-bit.

Thanks for reporting the issue. I have added #[cfg_attr(not(target_pointer_width = "64"), ignore)] in proc-macro2 1.0.85.

Great, thank you!
