Blogroll/Lins Menu not visible in my backend?

well, i'm confused. I can't seem to find out why my "Links" Menu doesn't show up in my wordpress admin.

I have this in my functions.php file …

add_action( 'admin_menu', 'remove_links_menu' );

function remove_links_menu() {
    remove_menu_page('themes.php'); // Appearance
    remove_menu_page('tools.php'); // Tools
    //remove_menu_page('link-manager.php'); // Links
    //remove_menu_page('edit-comments.php'); // Comments
}

However it clearly says, that link-manager.php is not removed. If comment-out the entire action the themes and tools Menus are showing back up. However the link-manager is never visible.

Any ideas?
