+ Merge patch for rdar://problem/22633105.
+
+ 2015-09-10 Brent Fulgham <bfulgham@apple.com>
+
+ [Win] Re-export a few symbols for backwards compatibility
+ <rdar://problem/22633105>
+
+ Reviewed by Dean Jackson.
+
+ Check in a workaround (in a custom branch) to re-export a few JavaScriptCore
+ functions that had been erroneously exported by WebKit in older builds. This
+ is needed so that we do not break certain old software still being used.
+
+ * WebKitDLL.cpp:
+ (DllMain): Bind functions at startup.
+ (bindJavaScriptTrampoline): Find JavaScriptCore library functions and
+ re-export them from WebKit.dll.
+ * WebKitDLL.h:
+ * WebView.cpp:
+ (WebView::unused5): Work around a linker bug.
