I'm not sure which versions of Windows we support in general. But on
further thought I thought we only used hard links for xlog files on
systems where we knew they worked and just did a rename() on systems
without them. So I'm puzzled why we're trying to hard link on this
system. Perhaps we need to make this a run-time check instead of just
making it depend on the system.
