Not really.  It doesn't hurt anything with devices, but we should obey
the general rule only linking things don't differ in attributes that we
are preserving.  The code in unchanged_attrs() was expecting that the
mtime would have been compared in the unchanged_file() routine, but
that assumption is not true for some of the code paths that ended up
using the routine.

The latest CVS makes unchanged_attrs() ensure that the mtime is the
same.
