Yes. You are right.

There are a couple of things that could be done.

1) Remove all that are not explicitly deprecated, along the lines 
proposed before. This would only leave strstream, I think.

2) Error instead of warn when using the backward (ie, present but not 
deprecated headers) when using C++0x.
