- Unlink is now reentrant, or at least thread-safe.

- You can now make unlink() stop after a failed deletion attempt which
  failed because the object to be deleted was reported as being "in use".
  The libunix.a variant defaults to report the deletion to have succeeded
  under these circumstances and later tries to delete the files marked
  for deletion. See <dos.h> for a brief documentation of how to change
  the behaviour.
