* gdk/win32/gdkevents-win32.c (gdk_event_translate): Plug same
refcount leaks as in the X11 backend.
* gdk/win32/gdkgc-win32.c (gdk_win32_gc_set_values): Logging
cosmetics.
* gdk/win32/gdkwindow-win32.c: Similar changes as in X11
backend. Add _gdk_windowing_window_destroy().
* gtk/gtkcolorsel.c: Include correct backend-specific header.
Don't use XColor unless on X11. (No GDK_VISUAL_STATIC_COLOR
either, but these probably do exist on nanox?)
* gtk/gtkhsv.c: Use G_PI (fresh from <glib.h>) instead of M_PI
which isn't necessarily defined by <math.h>.
* gtk/gtkobject.c (gtk_object_init): Don't go up the class
ancestry past GtkObject.
* gtk/gtktypeutils.h: Mark GTK_TYPE_IDENTIFIER for export/import
from DLL on Win32.
* gtk/gtk.def: Update corresponding to recent changes.
* gtk/makefile.{cygwin,msc}: Updates.
