    It isn't portable C, and it's easy enough to avoid.
    * alloc.c: Verify SAVE_FUNCPOINTER bits, too.
    (make_save_value): Add support for SAVE_FUNCPOINTER.
    * keymap.c (map_keymap_char_table_item, map_keymap_internal):
    * print.c (print_object):
    Distinguish function from object pointers.
    * lisp.h (SAVE_FUNCPOINTER): New constant.
    (SAVE_SLOT_BITS): Adjust to it.
    (SAVE_TYPE_FUNCPTR_PTR_OBJ): New constant, replacing
    SAVE_TYPE_PTR_PTR_OBJ.  Change the only use.
    (voidfuncptr): New typedef.
    (struct Lisp_Save_Value): New member data[0].funcpointer.
    (XSAVE_FUNCPOINTER): New function.
