+       * src/m4.h (m4_placeholder): New prototype.
+       * src/builtin.c: Unify error message style.
+       (m4_placeholder): New function, warn if invoked.
+       (builtin_tab): Add m4_placeholder.
+       (m4_defn): Warn if placeholder is encountered.
+       (find_builtin_by_addr): Handle placeholder.
+       (find_builtin_by_name): Return placeholder on failure.
+       (m4_builtin): Treat placeholder as undefined.

+       Reported by Bruno Haible.
