We don't really need to discuss this now though, the overall point is 
that it uses rename now through ff_rename, and the new call should also 
use rename on all the same systems.

rename is used unconditionally in ff_rename as far as I can tell, so it 
would probably be OK to remove the unistd.h check in file.c for rename?
