title: Expected ; after top level declarator, error in xcode
body: <p>I am working with this <a href="http://ffmpeg.org/doxygen/trunk/libavcodec_2utils_8c_source.html" rel="noreferrer">utils.c</a> file in xcode, which has the following:</p>
  
  <pre><code> #if FF_API_AVCODEC_OPEN
      int attribute_align_arg avcodec_open(AVCodecContext *avctx, AVCodec *codec)
      {
          return avcodec_open2(avctx, codec, NULL);
      }
  </code></pre>
  
  <p>It's causing an <code>Expected ; after top level declarator</code>, error (during build) in xcode at this line: <code>int attribute_align_arg avcodec_open(....</code></p>
  
  <p>Why? and what should I do to resolve this.</p>
  
  <p>Thank you.</p>
