This allows the runtime to only link against the parts it needs, without
pulling in unnecessary parts like thread spawning, TLS and conditions. file: [b0d97cac69] check-in: [5358e9ea6a] user: js, branch: trunk, size: 3225 [annotate] [blame] [check-ins using] [diff]

Forgot to add 2017, even though I already did quite some changes in
2017. file: [93f43616e8] check-in: [44f45c2e35] user: js, branch: trunk, size: 3234 [annotate] [blame] [check-ins using] [diff]

This means that OFObject.h imports macros.h now, making it unnecessary

If threads.h exists, the thread_local from there is used. If it doesn't,
but _Thread_local exists, it's defined to that. As a last fallback, it

It is also required when using the Apple runtime on OS X prior to 10.7. file: [af6605d688] check-in: [85cbeeeb04] user: js, branch: trunk, size: 2748 [annotate] [blame] [check-ins using]
