harbour-core/harbour/include/hbapiitm.h
Przemyslaw Czerpak 85ffaae73a 2007-07-30 18:00 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/include/hbcompat.ch
    + added #xtranslate ISPOINTER( <xValue> )
    * simplified bit operator translations

  * harbour/include/hbapi.h
    + added #define hb_itemPutCStatic(...) hb_itemPutCConst(...)

  * harbour/include/hbapiitm.h
    - removed #define hb_retclenAdoptRaw(...) hb_retclen_buffer(...)
      it's not _exactly_ the same and in some cases it cannot be
      replaced so users should know what exactly they are doing

  * harbour/source/rtl/gttrm/gttrm.c
    + added some #ifdef OS_UNIX_COMPATIBLE for future non *nix ports

  * harbour/source/rdd/dbf1.c
    ! added RT error when someone tires to create DBF with more then
      2046 fields - without it corrupted files were created or GPF
      appeared

  * harbour/contrib/ole2/w32ole.c
    * changed hb_retclenAdoptRaw() to hb_retclen_buffer()
