title: Over 200 ~SYNTAX ERRORS~ in math.h for visual studio, which doesn't make sense
body: <p><strong>Using Visual Studio Express2013 for Windows Desktop, with a "Win32 Console Application" C++ project</strong></p>
  
  <p><em>(I'm doing a project for a course. In order to start, I have to import all of the project files that the instructor provided - there are tons (all .cpp and .h files), so I can't really copy-paste any of them here... but I don't think that's the issue anyway).</em> </p>
  
  <p><strong>When I hit "run debugger," I get nearly 200 syntax errors in math.h</strong> Even though math.h is what came with Visual Studio.</p>
  
  <p>All the errors seem really simple like:</p>
  
  <pre><code>"Missing ')' before identifier _X'"
  "'_X' : undefined identifier"
  "'floor' : definition of dllimport data not allowed"
  "syntax error : missing ';' before '+'"
  
  
  etc... these syntax errors go on into the 200s.
  </code></pre>
  
  <p><strong>(I would copy-paste the entire error log, but there are 262 errors, and they all have the file directory path in them, so it would be impossible for you guys to read)</strong></p>
  
  <p>Why do I have so many syntax errors in math.h if math.h is a file that comes from Visual Studio itself?</p>
  
  <p><strong>(I have been trying to figure this out for weeks, and I can't actually start working on the project until it compiles)</strong></p>
