Richard: I'm unsure about three of these, which were fixes in memset() calls in: - NSConcreteMapTable.m - NSConcreteHashTable.m - Additions/NSData+GNUstepBase.m Please can you check them? I think they are intended to zero the entire object (rather than the first word), but the lack of comments makes me unsure. Most changes were just tweaks to variable types. I've also removed some dead code from NSInvocation. This was small group of things that were marked for internal use only, but not actually referenced in the code anywhere. Other improvements: - NSArray / NSDictionary fixed up to use the 10.7 (ARC-friendly) prototypes. - getObjects:andKeys: implemented for NSDictionary (10.5 method) - NSPointerArray and NSHashTable now properly support weak objects. - Tests for weak objects in collections. git-svn-id: svn+ssh://svn.gna.org/svn/gnustep/libs/base/trunk@33621 72102866-910b-0410-8b05-ffd578937521
