* win32/win32.c, include/ruby/intern.h (rb_w32_fd_copy): implement

  for rb_thread_select() in thread.c.  the use of rb_fd_copy() is
  introduced in r33117.
  [Bug #5229] [ruby-core:39102]

* thread.c (rb_thread_select): must call rb_fd_init() before using
  rb_fdset_t.  see the implementations of rb_fd_init()s if you want to
  know the reason.
