The code I write needs to compile under several older versions<br>of Boost, as I&#39;m sure is very common.<br><br>I have been tripped up by using const_pointer_cast, which apparently<br>doesn&#39;t exist very far into the past.<br>
<br>As far as I can see, implementing this functionality is not trivial, because<br>it&#39;s easy to make a mess of the reference counts in shared pointers.<br><br>I&#39;d like to know when this functionality was introduced, but with the older<br>
documentation offline at the moment I&#39;m a bit scuppered. I thought of<br>downloading old versions from source forge, but find there&#39;s  a gap<br>between 1.33.1 and 1.38<br><br>Any ideas how I can find out?<br><br>Thx<br>
