+// Other libc++ headers use <cstdint> but libc++'s <cstdint> complains if it
+// thinks <stdint.h> is not its own wrapper, so we define _LIBCPP_STDINT_H.  We
+// always get the real <stdint.h> before the libc++ with the way the include
+// paths are set up, which is necessary because of other headers where
+// preempting libc++'s header is unavoidable for the kernel environment.
