You can revert this change and make the patch smaller! :-)

I think this seems good overall, but fails to build on any of the mac platforms. This might be an SDK difference between Sierra and High Sierra. Likely just a missing include. r- to fix the build.

Did you change this on purpose? Fine if you did, but sometimes Xcode shuffles things around for arbitrary reasons (and you could revert this to make the patch smaller and easier to apply)

Please revert this whitespace-only change.

We usually have these conditional includes in a separate area.
