Okay, that's a good answer to my question. I'm still unsure whether we should be using `DISABLE_NEW_COUNT` globally like this, or perhaps doing some localized fix such as putting `#ifndef _WIN32` around each guard variable declaration. So I don't object to this fix but I also feel like I'd like to see someone else's opinion/approval rather than making me be the second approver.
