+  * core: Limit ap_pregsub() to 64MB, add ap_pregsub_ex() for longer strings.
+    The default limit can be adjusted at compile time using AP_PREGSUB_MAXLEN.
+    mod_setenvif: Log error on substitution overflow.
+
+    IMPORTANT: This could break existing configurations which rely on 
+               substitutions > 64MB.  Those sites need to rebuild with an
+               override of AP_PREGSUB_MAXLEN.
+               2.4.x has a much smaller limit on ap_pregsub() because that change
+               was introduced with the new release.
+
+    trunk patch:
+       util.c: too many to list, as it is tied up in other added features and follow-
+               up fixes; I started with 2.4.x HEAD and backed out some semantic changes
+               in the code of interest
