When assigning a pointer to an object that is allocated on the stack to the heap, send a -copy message. This lets you cast blocks to id and then assign them to ivars without anything breaking. Apple's 'solution' to this is to segfault, which is not particularly elegant. This code is also quite an ugly hack (it just checks whether the object is allocated within a couple of pages of the current stack frame), so I might remove it before release.

Lock the GC mode once something has queried it. All of the GNUstep code that

does run-time detection of whether to use GC calls objc_collecting_enabled()
(sometimes indirectly, via NSGarbageCollector) to see if we're in GC mode.
After any of these calls, it is not safe to switch modes.

Sometimes people assign things like classes to __weak pointers. This confuses the GC, because it expects to be able to finalize / delete things that are the target of disappearing links.

Use typed allocations for the hash table entries. This makes sure that the GC won't treat the jump table bitfield as a pointer.

Store the refcount structures inside the hash table, rather than in a chained structure. This uses less space and should be easier for the GC to scan (less cache used).

First pass at implementing Apple-compatible GC using Boehm. Still needs some tidying, but the following work:
...
- __strong pointers, preventing objects from being freed
_ __weak pointers are automatically freed when the last remaining __strong pointer goes away
- objc_gc_{retain,release}_np() functions, which can be used to implement CFRetain() and CFRelease() (adds an reference count - the object will not be collected until after its last retain is gone.
