When the ATOMIC_MOVE option is specified then it is allowed to replace 
the target file if it exists. In other words, it is not required to fail 
if the target exists. An implementation can't first check if the file 
exists because the overall operation must be atomic. One annoyance, as 
Andrew suspected,  is that Windows returns its equivalent of "access 
denied" for both the permission denied case and the case that the target 
is a directory. Is C:\Copy2\Macros2 is a directory?
