If you use 
	gtk_window_set_title (GTK_WINDOW(window), RAW_CANON_TITLE);
instead of
	gtk_window_set_title (window, RAW_CANON_TITLE);

There is no warnings.  AFAIK, that is why the GTK_WINDOW() macro
exists.  Isn't that expected behaviour, and part of the GTK+ type
safety?  The prototype is:

void gtk_window_set_title (GtkWindow *window, const gchar *title);

So the function is expecting a GtkWindow pointer, not a GtkWidget
pointer?

Call me crazy, but I doubt this has anything to do with Anjuta at all. 
Try compiling manually, as in:

$ gcc `pkg-config --cflags gtk+-2.0` testgtk.c -c

testgtk.c: In function `main':
testgtk.c:10: warning: passing arg 1 of `gtk_window_set_title' from
incompatible pointer type
