* 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
* ^ ^
* | |
* 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 unlikely event that SpiderMonkey ever implements 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.
