[smartmontools-support] Compiling smartctl on Windows

[Eaton Zveare]

Hi Christian, the line endings/format are correct in the files I have. I
did not need to make changes.
I made the int128 change and it actually made no difference. Digging
deeper, I found that I also had to remove these defines:

   - HAVE_UNISTD_H
   - HAVE_ATTR_PACKED

Only then did VS 2022 finally compile. You didn't have to remove those
defines to get it to work?
