Subject: Patch from Vladimir:     1) fixed a bug that could crash df, mount,
 and umount applets if the root     device name was longer then the word
 "root" (/dev/loop1 vs /dev/root) -     2) severl functions needed static
 declaration in the umount applet     3) update declaration for function in
 last_char_is() in libbb
