* $ONELINER$
* 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. )
* RETURN
