yap-6.3/H/ihstruct.h
Vítor Manuel de Morais Santos Costa 98f79484ae change throw mechanism to fit better with cleanup mechanism: 
- balls are now stored off line and recovered by Prolog code when everything
is safe.
- if a ball exists, throw uses the *existing* one (be careful not to have one
laying around).
- Jump routine cleans up every cp except ones for setup_call handling, backtracking simply calls setup handlers.
