In its initial form, the changes are tested on Linux. Later on, I'll do cross-platform builds to make sure there aren't any, say, windows-specific changes that are needed as well.

I can file a follow-up umbrella bug with the original list of ~200 warnings so the constructors and initializers in question can be examined to see if they should be updated.
