Grepped for "include <gnome" and "include <libgnome".
There was only one hit in ./gconf/gnome-testclient.c.

The explicit headers here should probably be instead:
   #include <libgnomeui/gnome-app.h>
   #include <libgnomeui/gnome-ui-init.h>
as there is
   gnome_init(PACKAGE, VERSION, argc, argv);
   app = gnome_app_new("gconf-test", "Testing GConf");
   gnome_app_set_contents(GNOME_APP(app), entry);
in the code.
