oldXMenu/X10.h just contains some data structures.  Maybe these where related 
to X10 at some point, but they no longer are, there are just structures used 
by the code.  It is bad name for that file though.

I don't know if oldXMenu is used (it is kind of strange looking :-), but it 
compiles and works.  But I suspect that those that can't use any X toolkit use 
Lucid.  I'd say we can get rid of it.

As I said in another mail, I think we can assume R6 or newer, and remove all 
three of HAVE_X11R[456].
