* gdk/gdkcursor.h (struct _GdkCursor): s/refcount/ref_count/.
* gdk/x11/gdkcursor-x11.c (gdk_cursor_new_from_pixmap):
* gdk/x11/gdkcursor-x11.c (_gdk_cursor_destroy):
* gdk/gdkcursor.c (gdk_cursor_ref): insert assertments for the
parameters given and cursor->ref_count. coding style fixups.
* gtk/gtksocket.c (gtk_socket_class_init): parent class is GtkContainer,
not GtkWidget.
* gtk/*.h: applied patch from Mathieu Lacage <lacage@email.enst.fr> to
fix up widget macros and add _GET_CLASS() variant.
* gtk/*.c: some GtkType fixups.
