Strange.  I don't understand how this:

  #define lisp_h_XSYMBOL(a) \
     (eassert (SYMBOLP (a)), \
      (struct Lisp_Symbol *) XUNTAGBASE (a, Lisp_Symbol, lispsym))
  # define XSYMBOL(a) lisp_h_XSYMBOL (a)

and this:

  INLINE struct Lisp_Symbol *XSYMBOL (Lisp_Object);

can live together.  Can you explain?

Thanks, I already fixed those, and will push shortly, as soon as the
lisp.h problem is resolved.
