ruby--ruby/st.h
knu 91b9d37a85 * st.h, st.c: Introduce new conventional typedef's, st_data_t,
st_compare_func_t, st_hash_func_t and st_each_func_t.

* st.h, st.c: Do explicit function declarations and do not rely on
  implicit declarations.  On such platforms as IA64, int argument
  values are NOT automatically promoted to long (64bit) values, so
  explicit declarations are mandatory for those functions that
  take long values or pointers.  This fixes miniruby's coredump on
  FreeBSD/IA64.

* class.c, eval.c, gc.c, hash.c, marshal.c, parse.y, variable.c:
  Add proper casts to avoid warnings.
