I doubt hazard builds are supported on Windows.

Hm, yeah, I should figure out how to make it produce a decent error message on Windows.

./mach hazards bootstrap works, so perhaps block it first? 😛 What exactly blocks it from working btw?

(In reply to Kagami :saschanaz from comment #3)

What exactly blocks it from working btw?

The hazard analysis uses sixgill, a gcc plugin, to extract the needed information from a compile. We don't support gcc on Windows.
