Ron Pinkas 0c2228a024 2000-11-30 18:25 UTC+0800 Ron Pinkas <ron@profit-master.com> 
* include/hbmacro.h
   * source/macro/macro.y
   * source/vm/macro.c
     ! Renamed hb_compParse() to hb_macroYYParse(). We already have hb_macroParse() and hcompparse()

   * source/compiler/harbour.y
     * Added token GET (not used) just so that harboury.h is compatible with harbour.sly

   * source/rtl/tgetint.prg
     * Reverted to use _1 and == NIL to not break Clipper compatibility.

     /* Ryszard, if you want to re-introduce PCount() and HB_PVALUE(), I'll ask (since I wrote this original code)
        that you protect it with #ifdef FLEX etc. If you do I would suggest you further protect it with #ifdef STRICT...
	becuase this will defintly break strict compatability. */
