Unable to build boost 1.60 with Visual Studio 2015 Pro
<p>Platform is Windows server 2012R2.  Toolsets installed are VS2015 with update 1 and Windows Driver Kit 10.</p>

<p>I run the "VS2015 x64 Native Tools Command Prompt", navigate to my unpacked boost_1_60_0 folder and run bootstrap.bat (have also run with an option 'msvc').</p>

<p>It quickly fails:</p>

<pre><code>Building Boost.Build engine

Failed to build Boost.Build engine.
Please consult bootstrap.log for further diagnostics.

You can try to obtain a prebuilt binary from

   http://sf.net/project/showfiles.php?group_id=7586&amp;package_id=72941

Also, you can file an issue at http://svn.boost.org
Please attach bootstrap.log in that case.

<p>Any thoughts why I cannot build?  <a href="https://studiofreya.com/2015/12/19/how-to-build-boost-1-60-with-visual-studio-2015/" rel="noreferrer">This site</a> suggests it should be very straighforward.</p>
