+        Upgrading this package to a new major version will require rebuilding
+        of many other packages. If some packages that use the librares built 
+        by icu4c-&icu-major; are rebuilt, they will use the new libraries 
+        while current packages will use the previous libraries.  If the 
+        linux application loader (/usr/lib/ld-linux-x86-64.so.2) determines
+        that both the old and new libraries are needed, it will probably
+        cause an address conflict when resolving needed symbols and will 
+        result in the application failing.
