*
* This class allows standard text output to be displayed on
* text window for Windows CE. Generally, all ACE output will
* go through under CE if and only if user uses WindozeCE
* implementation by using main_ce instead of main.
* Also, for the easier debugging purpose, object pointer of
* this class can be gotten from ACE_Log_Msg::msg_callback()
* and then can be used directly by user just like cout stream.
