Node references it these days. Also replace the no-op modes with negative numbers rather than zero. Stream ciphers like RC4 report a "mode" of zero, so code comparing the mode to a dummy value will get confused. (I came across https://github.com/nodejs/node/pull/23635, though we'd have run into it sooner or later anyway. Better to just define the value and avoid ifdef proliferation.)
