this patch should probably be reworked to account for this change: https://bugs.webkit.org/attachment.cgi?id=28824

Reopening because the change was reverted.

patch v2

I think this patch should be safe. I see no reason why any 32-bits platforms couldn't use the second definition, while 64-bits platforms (only x86-64 at the moment) use the first one.

It makes things simpler on the long term, IMHO.

I think you want something like this here:

#if PLATFORM(X86_64) || PLATFORM(MAC)

That's because your patch will disable the usage of this struct for x86-macs, which is not desired in my experience with similar patches.
