title: What is xutils.h, and what cflags/libs/packages do I need?
body: <p>I am thinking about maybe creating my own modified version of a GTK2 libwnck widget. In the source files of these widgets, it includes a file called <code>xutils.h</code>. This header file is present in GNOME's libwnck git repository, but it is not present in my distro's libwnck header files.</p>
  
  <p>I have tried searching for an <code>xutils</code> package for Arch Linux, but I cannot find such a package. I also looked in Fedora's libwnck header files, and that does not have an <code>xutils.h</code> file either.</p>
  
  <p>Here are my questions:</p>
  
  <ul>
  <li><p>What cflags/libs do I need in order to use this header file, or else what packages do I need to install?</p></li>
  <li><p>Why is the <code>xutils.h</code> file not present in my distro's libwnck header files?</p></li>
  </ul>
  
  <p>This program should be able to be linked against a distro's stock libraries. Potential users should not be expected to download and compile other libwnck source files.</p>
  
  <p>Please note that the header file I am looking for is called <code>xutils.h</code> (with an "s"), not <code>Xutil.h</code>.</p>
