32-bit platforms aren't gone yet. But that isn't the problem. The problem is that on 64-bit platforms the
L and UL suffix mean different things depending on the platform.  So yes, I think U without the length suffix
would have been better.  Not sure it's worth fixing at the moment; these all look harmless. And there might
be a future effort to do a thorough scrubbing in this area. It turns out there are *lots* of these.
