* harbour/contrib/rdd_ads/ads1.c
    * cleaned BCC warning

  * harbour/include/hbapi.h
  * harbour/source/vm/arrays.c
    + added set of hb_arraySet*() functions - I hope they will help 3-rd
      party developers to eliminate using C stack level HB_ITEM and
      reduce usage of potentially danger function like hb_arrayGetItemPtr()

  * harbour/include/hbapiitm.h
  * harbour/source/vm/itemapi.c
    + added hb_itemReturnRelease()

  * harbour/include/hbcompat.ch
    + added hb_pvalue() <-> pvalue() translations

  * harbour/source/vm/pvalue.c
    + added support for 2-nd parameter for assugb operation, f.e. now
         hb_pvalue( 3, "abc" )
      sets "abc" to 3-rd function parameter

  * harbour/source/compiler/gencc.c
  * harbour/source/compiler/hbopt.c
    ! fixed two buggy optimizations
