list author’s posts in author.php

The easiest way would be to simply add:

global $query_string;
query_posts( $query_string . '&posts_per_page=-1' );

just before your code so you get :

<?php
global $query_string;
query_posts( $query_string . '&posts_per_page=-1' );
while (have_posts()) : the_post(); ?>
     <li><a href="https://wordpress.stackexchange.com/questions/71127/<?php the_permalink() ?>"><?php the_title(); ?></a></li>
<?php endwhile;?>
