harbour-core/harbour/source/rtl/cdpapi.c
Przemyslaw Czerpak d495e5ad00 2006-05-19 21:05 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/bin/hb-func.sh
    * added support -go[0-3] and other -g* switches to xhb* scripts

  * harbour/include/hbapi.h
    + added ISSYMBOL() macro
    * formatting

  * harbour/include/hbapirdd.h
    * changed definition of SUPERTABLE for optional dynamic overloading
      this modification will not effect existing code

  * harbour/include/hbrddfpt.h
  * harbour/source/rdd/dbffpt/dbffpt1.c
    * added support for NIL value in SIX3 FPT files

  * harbour/include/hbcomp.h
  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/genc.c
  * harbour/source/compiler/gencli.c
  * harbour/source/compiler/genhrb.c
  * harbour/source/compiler/genjava.c
    ! message symbols are not function symbols - cleaned the HB_FS_MESSAGE
      usage and fix the problem with registering static function in global
      symbol table

  * harbour/source/compiler/gencc.c
    ! fixed typo in compilation for platforms 64 bit LONG

  * harbour/include/hbvmpub.h
  * harbour/source/compiler/cmdcheck.c
  * harbour/source/vm/asort.c
  * harbour/source/vm/evalhb.c
    * formatting

  * harbour/source/rdd/dbcmd.c
    * formatting and some minor clean-up

  * harbour/source/rdd/workarea.c
    * added default SYSNAME method
    ! fixed possible memory leak when APPEND failed in TRANSREC method

  * harbour/source/rdd/hsx/hsx.c
    ! fixed using HS_ADD()/HS_REPLACE() without STRING/BLOCK expression

  * harbour/source/rtl/cdpapi.c
    * cleaned GCC4 warning

  * harbour/source/rtl/do.c
    * changed to keep parameter references in DO() function. Now it works
      like IIF()/EVAL()

  * harbour/source/vm/classes.c
    * removed some definitions repared from hbapi.h
    + added support to passing function references as HB_IT_SYMBOL

  * harbour/source/vm/dynlibhb.c
    ! fixed GPF in HB_LIBDO called with wrong parameter

  * harbour/source/vm/hvm.c
    ! fixed hb_rddGetFieldValue() to not operate on unallocated stack area
      it could cause unpredictable results when RDD had to access HVM, f.e.
      for evaluation some pending relations. The whole code should be
      carefully checked and to not operate on hb_stackTopItem() if other
      functions are called to make the HVM fully reentrant.
    + added commented out support for passing HB_IT_SYMBOL as function
      pointer
    * formatting

  * harbour/source/vm/itemapi.c
    * return "S" for HB_IT_SYMBOL by hb_itemType()
    * formatting
