I don't think getopts knows how to parse words as options (and not as 
non-GNU-style, certainly). You are probably better off writing your own 
parser, something like this:

while [ $1 ] ; do
        [ ${1:0:1} = '-' ] || break
        case ${1:1} in
                help) echo help;;
                c*)
                        if [ ${1:1} ] ; then arg=${1:1}
                        else shift; arg=$1
                        fi
                        echo "arg of -c is $arg"
                        ;;
                *)
                        echo "bad option, $1";;
        esac
        shift
done
