Ping on this set since the only posted negative review of it earlier
was the lack of a non-insider SDK which contained these structures,
and that is now fixed as Microsoft actually published a newer stable
SDK.

It might not be as important for wine (at least for now), but projects
such as mingw-w64 seem to utilize wine as their upstream for DirectX
related headers, and synchronize them periodically.

Getting these definitions into wine would thus help this stuff go
downwards without people resorting to manual additions (which may get
lost in a later synchronization), or adding custom compatibility
headers into projects such as FFmpeg.

Best regards,
