There is no CFURLRequest object in the Cairo build, so it looks like
we've somehow got a bit of CFNetwork stuff creeping into the build.

The WebCore/platform/network/curl/ResourceRequest.h defines a stub of
cfURLRequest that should be supplying this implementation.  It looks
as though the WebCore/platform/network/cf/ResourceRequest.h is
actually getting used in your build.

I think the problem is that sometimes the post-build target doesn't
copy the ResourceRequest.h from the curl subdirectory, and you get
into this state.

For now, just copy the ResourceRequest.h (and perhaps the
ResourceResponse.h for good measure) from the
WebCore/platform/network/curl directory to your
$(WebKitBuild)/include/WebCore directory and you should be able to
rebuild just the WebKit.dll and it will link.

Perhaps the copy is not working right; I'll take a look at it and see
if something needs correcting.

Thanks,
