The FAT32 issue is a separate issue - Windows returns
STATUS_INVALID_DEVICE_REQUEST when attempting to get or set ACLs on a
filesystem that cannot handle them.  Linux at least returns no error as long as
the file or directory belongs to the user.

On a POSIX system, chmod will return EPERM when attempting to change the mode
of a file or directory that does not belong to the user, even with ugo+rwx
permissions.
