I posted earlier today, and I think now that the problem might not be RICE at all. I just tried to compile something that I <i>know</i> should compile properly, which does not use RICE, and it didn&#39;t work with a <i>different</i> boost library (in this case &lt;boost/unordered_map.hpp&gt;).<div>
<div><br></div><div>I&#39;m not really sure how to troubleshoot this. I know I upgraded recently from boost 1.41 to 1.43, but I can&#39;t see how that would be the issue. Perhaps I somehow have multiple versions of boost hidden here and there and it&#39;s trying to use the headers from one but libraries from another?</div>
<div><br></div><div>For example, compiling this file:</div><div><br></div><div>#include &lt;boost/unordered_map.hpp&gt;</div><div>int main() { return 0; }</div><div><br></div><div><br></div><div>Gives these errors:</div><div>
