Why not a separate function?

#define FONTSET_SPEC(fontset)  	XCHAR_TABLE (fontset)->extras[3]

DEFUN ("fontset-spec", Ffontset_spec, Sfontset_spec, 1, 1, 0,
       doc: /* FIXME */)
     (name)
     Lisp_Object name;
{
  Lisp_Object fontset;

  (*check_window_system_func) ();

  fontset = check_fontset_name (name);

  return FONTSET_SPEC (fontset);
}

... etc.
