Did it just stop working? That code is from 2014?

What userspace are you running? Is it 32-bit ?

   What compiler is that?

Building with V=1 should show you.

These warnings seem like they're correct, but that code should never
actually run on 32-bit so it should be harmless.

But they're only warnings, so they shouldn't be breaking the build AFAICS.
