Microsoft never implemented the rules about deducing the type of the enum from the enumerator values. It would be an ABI break in some ways if they did that today. You could argue that truncating enumerators that were too wide was already a bug, but that's the status.

Instead, they implemented strong enums as a way to let the user explicitly say "yeah, I really want a uint64_t", so this code should work fine.
