// Function:  Trace
//
// Synopsis:  This function either logs a message to either stderr (if this
//            is a checked build) or to the system log.  It takes a variable
//            number of arguments.  Like printf, the first argument is a
//            format string.  Any subsequent parameters are replacements
//            interpolated into the format string in place of variables.
//
// Arguments: char *szMessage - the format string (or whole message w/o subs)
//            ... - subsequent arguments are interpolated into message.
//
// Returns:   void
//
// History:   sgasch Created Header    22 Jun 1999
