This sounds a bit strange.  Shouldn't the application
tell the library whether it wants GUI or not?

There is no way to get the value of gtk_initialized from
gtkmain.  A fairly safe check for a GUI running is

    if (gtk_main_level() > 0)
       ...

However this fails when Gtk+ is initialized but no main loop
is running.
