Hm, this, I really don't know :(

Some context for the other people:  when using AC_CONFIG_LINKS,
config.status is equipped with code to build the links:

  # Make a symlink if possible; otherwise try a hard link.
  ln -s $ac_rel_source $ac_dest 2>/dev/null ||
    ln $srcdir/$ac_source $ac_dest ||
    AC_MSG_ERROR([cannot link $ac_dest to $srcdir/$ac_source])

Now, the question is why we never used `cp -p' here.  Well, I guess
one reason is that Makefiles don't have rules to update this
dependency?  So if we actually have a copy, then the updating would
work?

What can we do to address this issue?  I like this simple solution,
but I feel I might be missing something, as it has never been done.
