Why is there no ms\do_ms.bat after perl Configure VC-WIN64A?
<p>I'm compiling OpenSSL with Visual Studio 2015. I have installed:</p>

<ol>
<li><p>Visual Studio 2015 on Windows 10.</p></li>
<li><p>ActivePerl-5.24.0.2400-MSWin32-x64-300558.</p></li>
<li><p>nasm-2.11.08-win32.</p></li>
<li><p>OpenSSL source code by git clone git://git.openssl.org/openssl.git</p></li>
</ol>

<p>What I did are:</p>

<ol>
<li><p>Create a batch file with lines below.</p>

<pre><code>@call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" x86_amd64
@set path=%path%;C:\Users\gchen\AppData\Local\nasm
</code></pre></li>
<li><p><code>perl Configure VC-WIN64A —prefix=C:\test\openssl</code></p></li>
</ol>

<p>Now I should do <code>ms\do_win64a</code>, but I can't find this batch file. In the directory <code>ms</code>, there are files</p>

<pre><code>2016/08/22  17:39    &lt;DIR&gt;          .    
2016/08/22  17:39    &lt;DIR&gt;          ..    
2016/08/21  14:23             3,646 applink.c

2016/08/21  14:23             2,268 uplink.h
</code></pre>

<p>but there is no ms-win64a.bat.</p>

<p>What did I do wrong?</p>
