I think you should be able to ignore the GDK warnings.

You are using the modified gdk_set_window_pointer.c right? The one that includes
gdk/gtkwin32.h directly? (I didn't get a response from you when I send the
updated version.)

If that one doesn't work, try this one. (The only different is that I include
<gdk/win32/gdkwin32.h> instead of <gdk/gdkwin32.h>)

I also attach a gdkprivate-win32.h in case yours is missing (google seems to
suggest that windows version of GTK is missing the gdkprivate-win32.h file).
This is from gtk-2.4.4
