 *  $ONELINER$
 *      Enable/disable the macro compiler runtime features.
 *  $SYNTAX$
 *      HB_SETMACRO( <nOption>, [<lOnOff>] ) --> <lOldSetting>
 *  $ARGUMENTS$
 *      <nOption> One of the HB_SM_* constants defined in set.ch.
 *
 *      <lOnOff> .T. to enable or .F. to disable a feature
 *  $RETURNS$
 *      HB_SETMACRO() return the old state of requested feature.
 *  $DESCRIPTION$
 *      This function enables or disables some features of the macro
 *      compiler. The Harbour is extending the macro features compared
 *      to an original set available in CA-Cl*pper. Enabling/disabling
 *      some of them allows to keep strict CA-Cl*pper compatibility.
 *
 *      Available features are:</par>
 *      <b>HB_SM_HARBOUR</b> - enables harbour extensions:
 *            operators: ++, --, +=, -=, *=, /=, ^=
 *            objects: assigments to an instance variable
 *
 *      <b>HB_SM_XBASE</b> - enables other Xbase++ dialects extensions:</par>
 *            expanding of expresions lists
 *
 *      <b>HB_SM_SHORTCUTS</b> - enables optimized evaluation of
 *            logical operators (.and., .or.)
 *
 *      <b>HB_SM_PREPROC</b> - enables preprocessing of commands
 *            This is meaningfull if Harbour is compiled with
 *            HB_MACRO_STATEMENTS flag
 *
 *  $EXAMPLES$
 *      INIT PROCEDURE IWANTCLIPPER()
 *        HB_SETMACRO( HB_SM_HARBOUR, .F. )
 *        HB_SETMACRO( HB_SM_XBASE, .F. )
