I reproduced and (hopefully) fixed it in CVS.  Thanks for the report.

However, there's another problem which I'm puzzeling over when trying
the above.  I created a hardlink from C:\WINDOWS\Fonts\vgaoem.fon to
the same file in my home directory:

  $ pwd
  /home/corinna
  $ ln /cygdrive/c/WINDOWS/Fonts/vgaoem.fon .
  $ ls -l vga*
  -rwxrwx---+ 2 Administrators SYSTEM 5168 Feb 28  2006 vgaoem.fon

That's nice, but then:

  $ rm -f vgaoem.fon
  rm: cannot remove `vgaoem.fon': Permission denied

And that occurs even though I'm administrator and the unlink(2) call
uses the FILE_OPEN_FOR_BACKUP_INTENT flag.  The same happens with all
hardlinks to files used by the system.  The NT status code returned when
trying to set the delete disposition flag is C0000121,
STATUS_CANNOT_DELETE.  None of the Windows native methods to delete
these hardlinks works.  I'm still puzzeled how to get rid of them.
Does anybody knows how to do that?
