Comment (by duncan):

 I don't think switching to `System.Win32.copyFile` is the right solution.
 Switching `SearchPathA` for `SearchPathW` is sensible though. We should
 really be using the W variants everywhere now since we do not support
 Windows 9x anymore and we do want proper support for Unicode file names in
 Windows.
