Source code in xxx.h are as following:

/* Forward reference of OsTimer. This is so it can be used in the
declaration
 * of OsTimerNotify
 */
  93  typedef struct _OsTimer OsTimer;
        typedef void (*OsTimerNotify)(OsTimer*);
        typedef struct _OsTimer {
          ListEntry        node;
          TimeT            time;    /* Time period of the timer in TimeT
units */
          OsTimerNotify    func;    /* Pointer to function called when timer
fires */
          TimeT            startTime;
100     } OsTimer;
but after compile, the error message is:
    xxx.h:100: redefinition of 'OsTimer'
    xxx.h:93: 'OsTimer' previously declare here

            why, thank a lot.......
