Cursor doesn't change on Windows

["Issac Trotts" <ijtrotts ucdavis edu>]

This code works fine on Debian but has no effect on Windows:

    GdkCursor *translation_cursor=NULL;
    ...
    translation_cursor=gdk_cursor_new(GDK_FLEUR);
    ...
    gdk_window_set_cursor(gtk_widget_get_root_window(gl_area),
        translation_cursor);

The Windows version of Gimp changes cursors all the time, proving that
it can be done.  It makes me wonder what I'm doing wrong, or not doing.
