    GTK-Doc: extra directories in FIXXREF_OPTIONS
    
    The links to external GNOME symbols works now. It is how it is done in
    GTK+.
    
    To avoid the warnings, the HTML documentation of GLib, GTK+ and Pango
    must be available, obviously. A quick way to add them, without
    rebuilding everything, is to install the doc packages from the
    distribution, and add symbolic links in the jhbuild prefix.
