title: Error when compiling with zlib 1.2.8 on windows
body: <p>I'm linking against zlib 1.2.8 in my application built with VS2012 and ICC 13.0. When I compile a file where &lt; zlib.h > is included <strong>before</strong> &lt; windows.h >, there is no problem. When &lt; zlib.h > is included <strong>after</strong> &lt; windows.h >, I got an error in &lt; zconf.h >, line 454 where the compiler tries to include &lt; unistd.h >. Worst than that, I put a <em>#pragma message()</em> just before this #include and the message doesn't appear in the build output window!</p>
  
  <p>I tried the famous <strong>WIN32_LEAN_AND_MEAN</strong> but it changed nothing.</p>
  
  <p>Does someone have an idea about the solution for this problem?</p>
  
  <p>Thanks! </p>
