    * io.c (set_binary_mode_with_seek_cur): reorder function qualifiers.
    * test/ruby/test_io.rb (TestIO#test_pos_with_getc): added.
      see [Bug #6179][ruby-core:43518]

    * test/ruby/test_io.rb (TestIO#test_pos_with_getc): updated.
      see [ruby-core:43550]

    * io.c (static int io_fflush): add the definition.
      Use it in set_binary_mode_with_seek_cur().

    * io.c (set_binary_mode_with_seek_cur): refactoring to split the
      content into io_unread(). Fix the possibility of buffer overflow.

    * io.c (io_unread): add new implementation for Windows. Previous one
      caused invalid cursor position using IO#pos with OS text mode. New
      one fixes the bug.

    * test/ruby/test_io_m17n.rb
      (TestIO_M17N#test_pos_dont_move_cursor_position): add a test for
      above bug.
