// FIXME: On Windows, we require all WebKit source files to include config.h
// before including any other files. Failing to include config.h will leave
// WTF_PLATFORM_CF and WTF_USE_JSC undefined, causing build failures in this 
// file. But Mac doesn't have a config.h for WebKit, so we can't include the 
// Windows one here. For now we can just define WTF_PLATFORM_CF and WTF_USE_JSC
// manually, but we need a better long-term solution.
