I don't really see the practical rationale for changing from `_chsize` to `_chsize_s` though - if the only difference is that the latter returns the actual error code instead of `-1` on error, but we still do `return ::_chsize_s(fd, length) ? -1 : 0;`, there's not much point in doing that instead of just `return ::_chsize(fd, length);` right? Or is there some other aspect that isn't spelled out here?

`_chsize` uses a long size parameter, which is 32 bits on Windows, while `_chsize_s` uses `__int64`. Maybe I should add that to the commit comment.
