Can you please check if the two are compatible?

Ivan, thank you for asking about this. I had thought that the two were
compatible at least for the rename function (though not all CRT functions).
Your question prompted me to double-check, and it turns out that I was
mistaken. They are not compatible.
Here is a new version of the patch that uses conditional compilation to pass
the return value of {{GetLastError}} to {{throw_ioe}} when running on Windows.
I retested this on Windows and Linux with native build. I confirmed that
{{rename}} is setting the value of {{GetLastError}} when it fails.
> TestNativeIO#testRenameTo fails on Windows due to assumption that POSIX errno
> is embedded in NativeIOException

> HDFS-4428 added a detailed error message for failures to rename files by
> embedding the POSIX errno in the {{NativeIOException}}. On Windows, the
> mapping of errno is not performed, so the errno enum value will not be
> present in the {{NativeIOException}}.
