why don't you write code for the oldest version you need to support?  
the documentation for some old versions is still online. just change  
the version number in the URL. even older versions should still be  
available for download.

boost library authors usually keep the breaking changes for new  
versions to a minimum and document them.
this is probably easier than backporting.
