The pains of standardising a C++ library with complex symbols like STL...

WebKit also has a platform plugin, though I confess I don't know how it works 
exactly.

There are no Qt plugins in static builds. By definition, Qt plugins link to Qt. 
But if Qt is statically linked, then the only way that the plugin can link to 
Qt is if it is also statically linked into the application.
