Since this patch only alters the kdeinit case, it has no effect on plugins. 
or anything else for that matter.

For the plugin scenario, the correct way would be to specify what is 
considered public and what not (ie. like QT_EXPORT in QT). E.g. define an 
extra class that is exported to plugins and make the rest private to the 
app. The extra class then acts as the plugin interface.

Added bonus is the better code generation.
