Could it be that one of your systems uses a FAT32 drive, which does not
support hard links?  I couldn't reproduce your failure.

But speaking of hard links and tar, I find it annoying that setup.exe
won't even try to create hard links when a tar file requests them.  A good
example of this is the git-1.4.4.4-1.tar.gz2 package - it contains 55 hard
links to usr/bin/git.exe, but setup.exe unpacks it into 55 separate files,
rather than a single file, thus occupying 26 megabytes more hard drive
space than strictly necessary on NTFS.
