Comment:
this is not entirely correct, as the value is not `0100000` on all platforms

the block should look like this:

```
#if defined(__x86_64__) || defined(__i386__) || defined(__mips__)
#define O_LARGEFILE_REAL 0100000
#elif defined(__powerpc__)
#define O_LARGEFILE_REAL 0200000
#else
#define O_LARGEFILE_REAL O_LARGEFILE
#endif
```

(this is equivalent to how it's done and working in chromium)
