title: Still get 'curl/curl.h: No such file or directory' in spite of all looks proper
body: <p>I installed on windows <code>curl 7.28.0</code> from <code>curl-7.28.1-devel-mingw32.zip</code> through <code>minGW</code> console to default directory like:</p>
  
  <pre><code>./config &amp;&amp; make &amp;&amp; make install
  </code></pre>
  
  <p>All needed headers (aka <code>curl.h, types.h ...</code>) I see in <code>C:\MinGW\msys\1.0\local\include\curl</code></p>
  
  <p><code>libcurl.pc</code> placed  in  <code>C:\MinGW\msys\1.0\local\lib\pkgconfig\</code></p>
  
  <p><code>libcurl.a</code>, <code>libcurl.dll.a</code> and <code>libcurl.la</code> placed in <code>C:\MinGW\msys\1.0\local\lib</code>.</p>
  
  <p>My <code>download_file.c</code> file includes are:</p>
  
  <pre><code>...
  #include &lt;curl/curl.h&gt;
  #include &lt;curl/types.h&gt;
  #include &lt;curl/easy.h&gt;
  ...
  </code></pre>
  
  <p>I try to compile the <code>C</code> code with followed command through <code>gcc</code>:</p>
  
  <pre><code>$ gcc -IC:/MinGW/msys/1.0/include/ 
        -IC:/MinGW/msys/1.0/local/include/curl
        -IC:/MinGW/msys/1.0/local/lib/pkgconfig
             -o download_file download_file.c -llibcurl -lcurl
  </code></pre>
  
  <p>with absolute path get the same error:</p>
  
  <pre><code>gcc -I/include/
      -I/local/include/curl
      -I/local/lib/pkgconfig
          -o download_file download_file.c -llibcurl -lcurl
  </code></pre>
  
  <p>But I still get an error:</p>
  
  <pre><code>download_file.c:21:23: fatal error: curl/curl.h: No such file or directory compilation terminated.
  </code></pre>
  
  <p>row 21 is <code>#include &lt;curl/curl.h&gt;</code></p>
  
  <p>What I did wrong? Please help. </p>
