title: Show OS tasks on Eclipse's outline
body: <p>I've got some C code that runs on JenOS, a proprietary OS used on some NXP microcontrollers to manage ZigBee communication. This OS has a specific syntax to define tasks, that reads as follows:</p>
  
  <pre><code>OS_TASK(APP_ZPR_Light_Task)
  {
      ...
  }
  </code></pre>
  
  <p>Where OS_TASK is defined as:</p>
  
  <pre><code>#define OS_TASK(a)        void os_v##a(void)
  </code></pre>
  
  <p>Obviously, these are not recognized as standard C functions, and thus are not displayed in the outline tab of Eclipse. Is there a way to include those in the outline without having to hack the source (I don't want to go there for obvious reasons)?</p>
