It's a constant, implemented in HTAccess.c like this:

            /*
             * Don't exceed the redirection_attempts limit.  - FM
             */
            if (++redirection_attempts > 10) {
                HTAlert(TOO_MANY_REDIRECTIONS);
                redirection_attempts = 0;
                FREE(use_this_url_instead);
                return NO;
            }

...and

    /*
     * Make sure some yoyo doesn't send us 'round in circles with redirecting
     * URLs that point back to themselves.  We'll set the original Lynx limit
     * of 10 redirections per requested URL from a user, because the HTTP/1.1
     * will no longer specify a restriction to 5, but will leave it up to the
     * browser's discretion, in deference to Microsoft.  - FM
     */
    if (redirection_attempts > 10) {
        redirection_attempts = 0;
        HTAlert(TOO_MANY_REDIRECTIONS);
        return NO;
    }

Someone might want to propose a configuration patch, e.g., to allow
lynx.cfg to modify that limit.
