** This file defines two tracing macros:
**
**     MI_RETURN(EXPR)
**     MI_RETURN_ERR(EXPR)
**
** These override the macros with the same names in MI.h and add printf
** tracing on onon-zero MI_Result objects (those not equal to MI_RESULT_OK).
** Functions that use these macros can enable tracing of bad return values
** by simply including this file.
