oh you're gonna lovehate this
- latest nightly won't compile old versions of winapi #49765
- Allow variant discriminant initializers to refer to other initializer… #50072

At some point we should do what @RalfJung suggested in #61723 (comment) since Ralf is right that this is so incredibly niche and imo clearly a bug...

Adjusted the comment to refer to #50072... Should be good to merge now. :)
