// 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
// USE_CF 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 USE_CF manually,
// but we need a better long-term solution.
