libxfce4mcs compile error

[Shadoe]

Just checked out the latest cvs (not the snapshot)
i get this when compiling libxfce4mcs

I have a older cvs that compiled fine  except for xfprint but i dont have a printer on this box so i lived with that. :)
Its running very nicely by the way. i havent had any glitches yet besides no xfprint.
