	* win32/win32.c (setup_overlapped, finish_overlapped): extract from
	  rb_w32_read() and rb_w32_write().

	* win32/win32.c (setup_overlapped): check the error code in addition
	  to the result of SetFilePointer() to determine if an error occurred,
	  because INVALID_SET_FILE_POINTER is a valid value.
