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 That comment is out of date.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and has been replaced by Gtk::Application.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.
