note 124785 added to function.fileperms

Windows has a very different file permission model to Unix and integrates them only minimally. Here's how Windows calculates the bitmask... u+w/g+w/o+w is set based on whether the file has the read only flag. u+r/g+w/o+w is always set. u+x/g+x/o+x is set based on whether $filename is an inherently executable file (e.g. bat) or a directory. Windows isn't integrating its ACLs at all.
