48     * Compile-time JS version configuration. The JS version numbers lie on the
49     * number line like so:
50     *
51     * 1.0 1.1 1.2 1.3 1.4 ECMAv3 1.5 1.6 1.7 1.8
52     * ^ ^
53     * | |
54     * basis for ECMAv1 close to ECMAv2
55     *
56     * where ECMAv3 stands for ECMA-262 Edition 3. See the runtime version enum
57     * JSVersion in jspubtd.h. Code in the engine can therefore count on version
58     * <= JSVERSION_1_4 to mean "before the Third Edition of ECMA-262" and version
59     * > JSVERSION_1_4 to mean "at or after the Third Edition".
60     *
61     * In the (likely?) event that SpiderMonkey grows to implement JavaScript 2.0,
62     * or ECMA-262 Edition 4 (JS2 without certain extensions), the version number
63     * to use would be near 200, or greater.
64     *
65     * The JS_VERSION_ECMA_3 version is the minimal configuration conforming to
66     * the ECMA-262 Edition 3 specification. Use it for minimal embeddings, where
67     * you're sure you don't need any of the extensions disabled in this version.
68     * In order to facilitate testing, JS_HAS_OBJ_PROTO_PROP is defined as part of
69     * the JS_VERSION_ECMA_3_TEST version.
70     *
71     * To keep things sane in the modern age, where we need exceptions in order to
72     * implement, e.g., iterators and generators, we are dropping support for all
73     * versions <= 1.4.
