See ziglang/fetch-them-macos-headers#2 for more details. The path forward looks like one of the following: * Ony provide headers for the oldest supported macOS (currently 10.13 but soon to be bumped to 10.14). * Provide headers for multiple versions, and select based on the Zig target OS version range minimum. * Don't try to provide macOS headers. If we don't tackle the version problem, we would have to re-introduce the ability to detect and depend on native system headers if we wanted to support C/C++ code that used newer OS definitions. This patch also adds support for `#include <mach/mach_time.h>`. Also related: #5236
