/** 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.  */
