7/3     Cygwin on NT4 question: is there any way to make the following work?

        % ls -l s
        -rwxrwxrwx    1 joeuser  mkpasswd     7512 Jul  3 15:36 s*
        % perl -p -i -e 's/define/FOOO/g' s
        Can't do inplace edit on s: Permission denied.
        % ls -l s
        ls: s: No such file or directory
        So perl says it can't write to the file, but it can, and then it
        deletes it.  This happens on every file I've tried.  TIA.
