I believe that bison (1.01) fails to actually do an "unlink"
on its output file if that file exists already.

Unfortunately, if the output file *does* already exist, and
if there are one or more hard links to it (other than the
output file itself) then Bison's unwillingness to actually
unlink before writting to the output file can causes
undesriable (and perhaps even disasterous) consequences.
