Ugly hack to fixup NXConstantString references to NSConstantString if linked against Foundation. Now, if you forget to specify -fconstant-string-class=NSConstantString when compiling, stuff will still work and GNUstep won't get confused.

Made Object less magic. For now, because there are some weird people who want to use Objective-C without Foundation, Object is still included. If you compile without defining GNUSTEP (which GNUstep Make does automatically) then you get the old behaviour. If you build with GNUSTEP defined:
...
+load will not be sent until both NSObject and NSConstantString have been seen.
NSObject will be set as the superclass for all metaclasses, not Object.
This is in line with Cocoa and should make it a bit easier for people porting code who have categories on NSObject and are confused that they don't work as expected.
Object and NXConstantString are now deprecated. They're staying here because I use them for producing reduced test cases for the runtime and compiler, but they shouldn't be used. I will probably remove them from the default build soon.

Added toydispatch to libobjc. This is an implementation of a tiny subset of libdispatch, requiring no kernel support beyond a standard pthread implementation. It is intended to be used for running asynchronous book-keeping tasks for libobjc, but might also be useful for other things so it's compiled as a separate library.

Fixed a bug with category loading. Previously, a method in a category that overrode a method in the superclass would only be picked up by subclasses that were not yet initialized.
...
Quentin: This was the category loading problem that you saw. It was dependent upon load order, so was difficult to reproduce, however a Smalltalk category on NSString overriding a method from NSObject demonstrated it (because GSString was always initialized by the time Smalltalk code is loaded because LKCompiler use it, but not by the time ObjC code is loaded).

Added hopscotch table implementation and rewrote the class table to use it. This is done so that the class table and protocol tables can share the same code (currently there is no protocol table).
...
Note that concurrent resizing has not yet been implemented. That means that there is a hard limit on the number of classes that can be loaded. This is currently set to quite a small number for testing, to stress the hash table. If you're experiencing problems as a result, then please let me know and I will increase it.

Fixed class_get_super_class() so that it actually works and simplified class_getSuperclass() to call it directly. This fixes numerous other corner cases, for example you can now throw a constant string as an exception and have it work correctly even if no constant string objects have been sent messages.
...
Hopefully this will fix a few other Heisenbugs and reduce the strength of the Mottola Effect.

Tweaked the +initialize order to work around some of the insanity in NSObject and NSAutoreleasePool's interaction in GNUstep. This code is incredibly fragile, and on the old runtime sometimes completely fails and crashes during startup, depending on the order in which the files were linked in -base and how the platform linker works. Hopefully now it should work in all cases.

Added run-time abort if the first ivar of a newly-loaded class does not immediately follow on from the previous one. This (hopefully, modulo some potential weirdness related to bitfields) means that we should now get programs refusing to start in most cases where they depend on frameworks that had their ABI change but didn't bump the library version. This seems preferable to the previous behaviour of corrupting memory (note that this won't catch the case where the superclass has its ivars rearranged, but remains exactly the same size and the subclass references the ivars).

Bug fixes in libobjc2:
...
- nil_method now returns 0, not receiver.
- Metaclasses actually get their dtables installed with the new ABI. For some reason this wasn't being done, so class messages didn't work with the new ABI. Now they do and (at least some) nontrivial programs work.
- Undid commenting out of the code setting the fast ivar access pointers. I can't remember why this was commented out, but it seems not to break anything. I have an LLVM pass that makes compiled code access these pointers, but it's not committed yet.

Removed assertion. I'm not entirely sure why it was there, but it was preventing Gorm running (along with anything else that provided categories on subclassed classes). I need some more testing to make sure that this didn't break anything else, but Gorm now runs correctly with the new runtime, so it seems like an improvement...
