      Macro
   $ONELINER$
      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:

      `HB_SM_HARBOUR` - enables Harbour extensions:
            operators: `++`, `--`, `+=`, `-=`, `*=`, `/=`, `^=`
            objects: assignments to an instance variable

      `HB_SM_XBASE` - enables other Xbase++ dialects extensions:
            expanding of expressions lists

      `HB_SM_SHORTCUTS` - enables optimized evaluation of
            logical operators (`.AND.`, `.OR.`)

      `HB_SM_PREPROC` - enables preprocessing of commands
            This is meaningful if Harbour is compiled with
            HB_MACRO_STATEMENTS flag

   $EXAMPLES$
      #include "hbmacro.ch"
      INIT PROCEDURE IWANTCLIPPER()
         ? hb_SetMacro( HB_SM_HARBOUR, .F. )
         ? hb_SetMacro( HB_SM_XBASE, .F. )
