* harbour/include/hbapi.h
  * harbour/include/hbexpra.c
  * harbour/include/hbexprb.c
  * harbour/include/hbexprop.h
  * harbour/include/hbpcode.h
  * harbour/include/hbxvm.h
  * harbour/source/common/expropt1.c
  * harbour/source/compiler/genc.c
  * harbour/source/compiler/gencc.c
  * harbour/source/compiler/gencli.c
  * harbour/source/compiler/hbdead.c
  * harbour/source/compiler/hbfix.c
  * harbour/source/compiler/hblbl.c
  * harbour/source/compiler/hbpcode.c
  * harbour/source/compiler/hbstripl.c
  * harbour/source/vm/hvm.c
  * harbour/source/vm/macro.c
    * changed support for XBASE++ extended syntax in expressions like:
         v:="1,2,3"
         x := a[ &v ]
         a := { &v }
         f( &v )
      Now all data is stored on HV  * stack without any external registers
      which have to be saved/restored or updated in chosen operation.
      This modification was necessary to make HV  * reentrant safe and it
      also eliminated some small overhead caused by old code.
      I hope I haven't break anything in compiler - Ryszard please fix me
      if I made sth wrong.

  * harbour/source/vm/hvm.c
  * harbour/source/compiler/harbour.y
    * revert FOR/NEXT stop condition to be Clipper compatible

   PCODE table has been updated and all .prg code which used modified PCODEs
   has to be recompiled
