<p><a href="https://github.com/falit" class="user-mention">@falit</a>: are you planning to finish this?</p>

<p>Splitting the clean-up like <a href="https://github.com/elfring" class="user-mention">@elfring</a> suggested would be just fine (and topic branches are a good way to do this).  In this case we only have two things: the header guards, and the versioning macros.  <a href="https://github.com/falit" class="user-mention">@falit</a>, if you want to redo this PR as changing just the include guards, we can take care of the versioning macros another time.</p>
