Take a look at the noacl option.  You'll want to apply that to whatever
mountpoint contains the target path of your copy operation.  If you want
to be surgical in the application, create a new mountpoint with this
option set and copy your files into paths within it.  Otherwise, you can
apply it to the cygdrive mountpoint so that the option applies to any
path under /cygdrive and UNC paths.

I'm not sure if it's possible to change the mount options of /,
/usr/bin, or /usr/lib since those mountpoints are implicitly defined.
Setting this option on them would probably break things anyway.  If your
target path is currently something like /home/whatever, set up a new
mountpoint with the noacl option and copy to that instead.
