- FIXME: This feature can cause core dumps when renaming multiple
symbols to the same name.
+* The `builtin' macro now has a special form, where if the first argument
+ is exactly the special token representing defn(`builtin'), the expansion
+ is the special token representing the builtin named in the second
+ argument. This allows regenerating a macro with a more efficient
+ mapping directly to a builtin function, rather than through textual
+ indirection through further expansions of `builtin'.

regular expression syntax used by M4. Without this option, M4 continues
to use EMACS style expressions. A new section in the info docs
