* harbour/ChangeLog
    * marked may last TODO note as DONE - thanks to Viktor and Mindaugas

  * harbour/include/hbmacro.h
    ! added missing const in hb_macroGenPCodeN() declaration

  * harbour/include/hbapi.h
    * added const to HB_CODEBLOCK.pCode

  * harbour/include/hbcompdf.h
    ! added missing const to HB_MACRO.string

  * harbour/src/pp/ppcore.c
  * harbour/src/common/hbstr.c
  * harbour/src/compiler/hbmain.c
  * harbour/src/compiler/hbfix.c
  * harbour/src/compiler/complex.c
  * harbour/src/compiler/hbdead.c
  * harbour/src/compiler/genc.c
  * harbour/src/compiler/hbident.c
  * harbour/src/compiler/gencc.c
  * harbour/src/compiler/hblbl.c
  * harbour/src/compiler/harbour.yyc
  * harbour/src/compiler/harbour.y
  * harbour/src/compiler/harbour.yyh
  * harbour/src/vm/macro.c
  * harbour/src/vm/codebloc.c
  * harbour/src/vm/itemapi.c
  * harbour/src/vm/hvm.c
  * harbour/src/rtl/hbjson.c
  * harbour/src/rtl/sha1.c
  * harbour/src/rtl/sha2hmac.c
  * harbour/src/rtl/hbsocket.c
  * harbour/src/rtl/hbbffnc.c
  * harbour/src/rtl/itemseri.c
  * harbour/src/rtl/filebuf.c
  * harbour/src/rtl/hbbfish.c
  * harbour/src/rtl/gttrm/gttrm.c
  * harbour/src/rdd/workarea.c
  * harbour/src/macro/macrolex.c
  * harbour/src/rdd/usrrdd/usrrdd.c
    * cleaned const pointer casting

  * harbour/src/rdd/usrrdd/usrrdd.c
    ! fixed very serious bug located during const pointer cleanup
      which should cause GPF on user code creating indexes

  * harbour/src/rtl/sha2.c
    * minor formatting

   ; TOFIX: Seems that there is sth wrong with src/rtl/sha1.c.
            Function SHA1_Transform() wrongly declares 2-nd parameter
            buffer[64] as const when in fact it changes it what can be
            seen if
               BYTE64QUAD16    *block;
            is changed to:
               const BYTE64QUAD16 *block;
            This casting which removes const hides potentially very serious
            bug - modifying readonly memory area. SHA1_Transform() changes
            the buffer so the 2-nd parameter must be declared without const.
            After such modification C compiler should warn when const buffers
            are passed to this function and such places should be fixed.
            In fact it seems to be only line 136:
               SHA1_Transform(context->state, &data[i]);
            Viktor can you look at it and fix the code?
