I'm sorry I was not very clear in my original message. I have implemented a custom GTK+ widget which relies on a C++ object internally. i.e. the widget structure contains an instance of a C++ class. My concern was that the constructor and destructor of the contained object were not being called. I had assumed that merely compiling as C++ would make it work... but now I realize it need not be so when allocated via g_object_new.
c++-gtk-utils looks like just what I need.
