  * Fix boot: it was avoiding autoreconfing
  Two problems here: find needs to dereference symbolic links (-L
  option, I really hope that's portable), and we need to notice when
  aclocal.m4 is updated.  
  
  Somehow I think this was easier when it just always ran
  autoreconf... what was wrong with that?

    M ./boot -8 +9
