By definition, weakCompareAndSwap crashes if built when !ENABLE(COMPARE_AND_SWAP). It would be safer for the code to fail to compile in this case.

It would be good to fix this. This would require making Bitmap somehow guard its calls to weakCompareAndSwap; right now it makes calls to weakCompareAndSwap by guarding them with a template enum parameter, and users to Bitmap configure that parameter accordingly. :-/
