title: MS detour MakeFile error
body: <p>I downloaded Detour Express 3.0 via MS (<a href="http://research.microsoft.com/en-us/projects/detours/" rel="nofollow">http://research.microsoft.com/en-us/projects/detours/</a>)</p>
  
  <p>My PC use <code>Intel i3 CPU</code> and <code>Windows 7 32bit</code>.</p>
  
  <p>In addition, I use <code>Visual Studio 2015 Community</code>.</p>
  
  <p>To install detour, I run <code>Visual Studio 2015 Command Prompt</code>.</p>
  
  <p>And do <code>NMAKE</code>(with all option)</p>
  
  <p>Then the error occurs.</p>
  
  <p>=========================================</p>
  
  <p>(Error is written in Korean. I translated it myself)</p>
  
  <pre><code>C:\Program Files\Windows Kits\8.1\include\um\dbghelp.h(1544): warning C4091: 'typedef ': 변수를 선언하지 않으면 '' 왼쪽은 무시됩니다.

  <p>What's wrong, and what should I do?</p>
  
  <p>====additional information ===</p>
  
  <p>In <code>Windows Kits</code> folder, there are 4 folders. <code>8.0, 8.1, 10, NETFXSDK</code></p>
  
  <p>I think this <code>Windows Kits</code> folder was installed when I installed <code>VS 2015</code></p>
  
  <p>Does it have any relationship with the error?</p>
