* Some third-party code uses the existence of IN_CLOEXEC/IN_NONBLOCK to detect
* the availability of inotify_init1. This is not correct, since
* `syscall(__NR_inotify_init1, IN_CLOEXEC)` is still valid even if the C
* library doesn't have that function, but for the time being we don't want to
* harm adoption to the unified headers. We'll avoid defining IN_CLOEXEC and
* IN_NONBLOCK if we don't have inotify_init1 for the time being, and maybe
* revisit this later.
