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