+Wed Nov 12 12:30:00 1997  Richard Frith-Macdonald  <richard@brainstorm.co.uk>
+
+	* src/Collection.m: ([Enumerator -dealloc]) added call dealloction
+	method in super class to fix memory leak.
+
+	* src/KeyedCollection.m: Removed initialisation and deallocation
+ 	methods for KeyEnumerator as these are done in its super class.
+
+	* src/NSCharacterSet.m: ([-invertedSet:]) added autorelease for data
+	object (created by mutableCopy) in order to fix memory leak.
+
+	* src/NSData.m: Replaced line accidentally deleted in section only
+	compiled in for systems without shared memory.
