/** An ELinks-specific replacement for JSFunctionSpec.
*
* Bug 1016: In SpiderMonkey 1.7 bundled with XULRunner 1.8, jsapi.h
* defines JSFunctionSpec in different ways depending on whether
* MOZILLA_1_8_BRANCH is defined, and there is no obvious way for
* ELinks to check whether MOZILLA_1_8_BRANCH was defined when the
* library was built. Avoid the unstable JSFunctionSpec definitions
* and use this ELinks-specific structure instead. */
