Ah, yes. Thanks. I'm looking at the source code now.

The documentation says that one need to have a Main for Main::~Main() to be called for cleanup, although the doc says "Of course I can't imagine any situation in which you wouldn't have a Gtk::Main."

But if I'm writing a C++ module inside a C application, will this be the case? Can this be resolved or ignored?

It can be ignored. That comment is out of date. Nowadays it's easy to imagine programs without a Gtk::Main. Most of Gtk::Main is deprecated, and has been replaced by Gtk::Application. The cleanup in Gtk::Main::~Main is not important. It just deallocates some dynamically allocated memory before the program finishes. Gtk::Application::~Application does not do it. The operating system will take care of it when the program has finished.

The init_gtkmm_internals method has a check in place so that calling it
additional times will do nothing.
