+#include <sysexits.h>
 #include <utility>
 #if LLVM_ON_UNIX
 #include <unistd.h> // getpid
 #endif
----------------
@rnk || @majnemer thoughts on making this:

```
#if LLVM_ON_UNIX
​#include <unistd.h> // getpid
#include <sysexits.h> // EX_IOERR
#else
#define EX_IOERR 74
​#endif
```

vs also guarding the check I added on L1409 with `#if LLVM_ON_UNIX`?
