Could you explain how to retrieve that viewer? I tried to retrieve it via
PlatformUI.getWorkbench(), but no luck. (I'm not too familiar with JFace, I 
admit)

This finally ends in a single listener, 
org.eclipse.cdt.internal.core.pdom.LanguageSettingsChangeListener and calls 
PDOMManager#update(). This seems to trigger re-indexing and updates the 
display of open editor views, which is fine.

Yes, this updates the #if sections in the C-editor views.
