Actually, there is only one call to profile_get_boolean() in
use_dns_uri() that needs a cast:

    ret = profile_get_boolean(ctx->profile, KRB5_CONF_LIBDEFAULTS,
                              KRB5_CONF_DNS_URI_LOOKUP, NULL,
                              DEFAULT_URI_LOOKUP, (int *)&use);
                                                  ^^^^^^^

and everything else compiles without error.
