Thank you.  I think Tom is also running make check-world.  I now have
an old RPI3 setup with a 32-bit OS, which is currently busy compiling
Postgres. I'll kick off a make check-world run once that's done.

ARM animals are already broken and per what Tom mentioned in [1], I've
pushed the patch.

Thanks again for taking the time to look at this.

David
