syntax error in /etc/init.d/boot_xconf

[Eike Lantzsch <zp6cge@gmx.net>]

Maybe I'm too daft to see it

Sun Jan  8 11:44:38 2006: /etc/rc2.d/S20boot_xconf: line 43: syntax error near 
unexpected token `('
Sun Jan  8 11:44:38 2006: /etc/rc2.d/S20boot_xconf: line 43: `      let 
LENGTH=($LENGTH - 1)'

iptohex () {
    IP=$1

    HEXIP=$(for ALL in $(echo "$IP" | tr "." " ") ; do
      if [ $ALL -lt 16 ] ; then
        echo -n "0$(echo -e "obase=16\n$ALL" | bc)"
      else
        echo -n "$(echo -e "obase=16\n$ALL" | bc)"
      fi
    done
    echo )

    LENGTH=8
    while [ $LENGTH -gt 0 ] ; do
      echo $HEXIP
      let LENGTH=($LENGTH - 1)				*(	-- line 43	)*
      HEXIP=$(echo $HEXIP | cut -c -$LENGTH)
    done
}

If I remove the () in line 43 the syntax error does not show up but does it 
still work as intended?

I would appreciate any hint. Thank you
