      Hi All,<br>
      <br>
      I am getting lots of below warnings while compiling GlusterFS in
      Fedora19. I don't remember seeing this warning couple of weeks
      back. Any suggestion how to fix this or turn this off? I have
      attached the make output with this email.<br>
      <br>
      Steps to reproduce the issue:<br>
      <ul>
        <li>/autogen.sh </li>
        <li>./configure --enable-debug or "./configure"</li>
        <li>make</li>
      </ul>
      Warnings:<br>

    I forgot to mention that, I am seeing this on latest master branch
    of GlusterFS.<br>
