8da720fc7a * Source/NSObject.m (__builtin_offsetof): Add workaround for build in missing 
in old versions of gcc.

4cdea64975 Make -base compile almost without warnings again. Fixes: 
- Using the correct format specifier
- Remove substringFromRange: (GNUstep extension) from NSString.h and use the non-deprecated version in -base.
- Delete definitions of methods that are the same in both a class and a category on that class (NSArray and NSObject).

Two files still have warnings:

- The GNUTLS stuff is using a load of deprecated APIs.
- xmlparse.m replaces a method using a category.  This method seems to always return nil.  Not sure what it's meant to do, or why it isn't a delegate of some kind.

8c89a86607 In -finalize, we're pretending to be the Objective-C runtime, so we need to 
actually use isa directly, rather than the safe version.  A better solution
would be to call object_dispose(), but this only works for objects created with
class_createInstance().

bb2e9d0627 When calling -.cxx_dealloc, look up the superclass before calling. This method 
may destroy the receiver's class, if it's a user-generated one, so we can't
guarantee that it is valid after the call.

48e1b94ef8 Change the order of the retain count and the padding, so the retain count is 
always the word before isa.

Switch to using the correct kind of alignof (the ABI alignment in structures,
not the preferred alignment of the type - this stops us from allocating 4 bytes
of padding on x86-32 where there is no need for any)

40456f7787 Remove the zone pointer from objects. Now we always query the zones to find the relevant pointer. Zones are still supported, but we now optimise for the case where they are not used. 
To disable zone support completely, NSAllocateObject() should ignore the zone and NSDeallocateObject() should skip the zone lookup.

2a2d7339d1 Switch the order of the reference count and the zone so that the reference count (in reference counted mode) is always immediately in front of the object. Please test this!! 
Opt NSObject into the fast path for ARC.  ARC will now not call the retain / release / autorelease methods on NSObject or any classes that inherit their implementation of these methods from NSObject.  In quick and dirty testing, this gives about a 10-20% speedup.

b08b2d0f34 More tweaks for garbage collection mode, including making NSNotificationCenter use weak pointers (things are never removed if it uses strong pointers because they remove themselves in the -dealloc method, which is never called, and can't remove themselves in the -finalize method because the -finalize method would not be called until after they have been removed - this is consistent with Apple behaviour). 
Gorm now works correctly when built with GC enabled.

6068e9484c Initial pass at implementing fully Apple-compatible GC. This requires the code to be built with -fobjc-gc or -fobjc-gc-only, and requires a runtime that implements all of the support functions (GNUstep runtime trunk or 1.5 when it's release). 
Currently, there are a few places where we should be calling NSAllocateCollectable() without NSScannedOption, but are actually calling NSZoneMalloc() unless we're in GC mode.  We should not need separate code paths for this anywhere outside NSZone, since NSAllocateCollectable() will work in non-GC mode as well.

A few of the changes should be tweaked slightly so that they do run-time tests.  For example, when compiling with -fobjc-gc, we may be linked against non-GC code, which will use -retain and -release but won't use the memory barriers.  Supporting this nicely is a lot of effort, and I'm not fully convinced it's a good idea.
