/* This plugin tests the correct operation of a PLUGIN_START_UNIT callback.
* By the time a PLUGIN_START_UNIT callback is invoked, the frontend
* initialization should have completed. At least the different *_type_nodes
* should have been created. This plugin creates an artificial global
* interger variable.
