How should HTTP server respond to 'If-Match' header when it's unsupported yet?

I have an HTTP server implementation with partial REST support. It doesn't support If-Match and If-None-Match yet but I am going to implement it eventually, just not in this release.

In this case, what response should the HTTP server when a client sends an HTTP PUT request with If-Match or If-None-Match header? Ignoring them and just updating the resource don't sound right because the client obviously wants the server not to update the resource.

What response the server should send then? I think the server at least should tell the client that those headers are not supported and thus the request has been rejected. Is there any status code dedicated to this sort of responses?
