It's more that the file in /tmp is created with group "wheel" which I am
not a member of, so mv (cp -p across file systems) generates that message.

I'm not sure.  Could chgrp the file in /tmp before moving, I suppose, but
is that portable?

This is for swish-e, an open source project.  We released a version
yesterday and people on BSD complained about that message.  I feel like the
message is harmless, but some would like to see configure run without any
warnings.  I have to explain how to run ./configure && make often enough,
so asking the user to install GNU mv might be too much.
