* eval.c (rb_respond_to): funcall respond_to? if it's redefined.
  [ruby-dev:25021]

* io.c (rb_file_initialize): [ruby-dev:25032]

* lib/ostruct.rb (OpenStruct::Marshaler): OpenStruct can be
  marshaled again.  [ruby-core:03862]

* io.c (rb_io_ctl): [ruby-dev:25019]

* io.c (io_fread): need not to null terminate.  [ruby-dev:24998]
