It'd have to be pretty old. As near as I can see from 
xnu/bsd/kern/sys_pipe.c, the st_ino field was zero (i.e., not random) 
even in xnu-792 dated 2005.

I'd be leery of changing this part of coreutils/src/copy.c without 
knowing more about exactly why bug occurs on (older?) Darwin, as 
weakening the check would make GNU 'install' easier to attack.
