* io.c (rb_f_syscall): type dispatch should be based on

  rb_check_string_type(), not FIXNUM_P(), because values may be a
  bignum.  [ruby-talk:72257]

* eval.c (rb_call0): should pass the current klass value to
  block_invoke, which may be called via "super". [ruby-core:01077]

* eval.c (block_invoke): now takes 4th argument "klass".

* eval.c (block_alloc): should propagate BLOCK_PROC to
  ruby_block.

* marshal.c (r_object0): should not use "yield" method, use "call"
  instead. (ruby-bugs-ja PR#476)
