ChangeLog
* io.c (io_cntl): F_DUPFD is platform dependent.
Mon Oct 25 13:28:00 2009 Suraj N. Kurapati <sunaku@gmail.com>
* include/ruby/ruby.h: declare ruby_bind_stack(). [ruby-core:26244]
* gc.c: implement ruby_bind_stack(). narrow GC scanning region
to ruby_bind_stack() boundaries in mark_current_machine_context().
