Gtk 2.4.2 on linux-fb fail to compile

["Victor Chen" <chen shengqi connet com tw>]

I found 2 bug in this version

first: GTK_SELECTION_MAX_SIZE(display) define same as X11, will now compile
I make it define as G_MAXINT.

second: _gdk_windowing_window_destroy_foreign undefine.
I add this to gdkwindow-fb.c, 
_gdk_windowing_window_destroy_foreign(GdkWindow *window)
{
    // do nothing in linux-fb
}

I think the I deal the first error correct. but dont know how to write _gdk_windowing_window_destroy_foreign, 
so leave it empty. have any danger?
