The GTK error is in WebCore::jsSubtleCryptoPrototypeFunctionUnwrapKey(), unrelated to this patch.

If possible, please use __weak id here.

Doesn't seem to be possible, as __weak only make sense when compiling under ARC, and WKPagePrivateMac.mm doesn't. Adding __weak here just generates a warning.

We're already storing the delegate in a WeakObjCPtr, but there doesn't seem to a way to mark the return value of a C function as __weak (or a parameter as __weak) without generating a compiler error.

I guess I could do something like:

#if !defined WEAK
#if __has_feature(objc_arc)
#define WEAK _weak
#else
#define WEAK
#endif

and then mark up the methods as WK_EXPORT WEAK id <...>; Does that seem right? We don't seem to use __weak in any of the other C-style APIs.
