// As of the 10.12 SDK, this is declared as reserved[9] for 64-bit platforms
// and reserved[4] for 32-bit platforms. It was expanded to reserved[5] for
// 32-bit platforms in the 10.13 SDK to provide proper padding, but because
// the runtimes that use versions 14 and 15 were built with SDKs that did not
// have this extra padding, it’s necessary to treat the element at index 4 on
// 32-bit systems as outside of the version 14 and 15 structure. This is why
// |reserved| is only declared a 4-element array, with a special end_v14
// member (not present in the native definition) available to indicate the end
// of the native version 14 structure and the 10.12 version 15 structure,
// preceding the padding in the 32-bit structure that would natively be
// addressed at index 4 of |reserved|. Treat reserved_4_32 as only available
// in version 16 of the structure.
// In the 12.0 SDK, 2 of the trailing UIntPtrs on 64-bit and
// 4 of them on 32-bit were replaced by two uint64_ts. On 32-bit, that
// awkwardly straddles end_v14. Since macOS 12.0 is 64-bit only, the proctype
// version of this struct only has these uint64_ts in the 64-bit version.
