    ! added protection against cyclic references in arrays
    * eliminated action parameter from hb_vmRequestReenter() /
      hb_vmRequestRestore()
    * moved s_lRecoverBase and s_uiActionRequest to HB_STACK structure
      for future MT HVM version
    + added internal item structure hb_struRecover - it's not real item
      but this structure is used to keep information about BEGIN SEQUENCE
      data - it reduce HB_STACK usage
    + added support for ALWAYS clause in BEGIN SEQUENCE
      The syntax is:
         BEGIN SEQUENCE
            <code>
         [ RECOVER [ USING oErr ] ]
            <recoverCode>
         [ ALWAYS ]
            <alwaysCode>
         END [ SEQUENCE ]
      It's guaranteed that <alwaysCode> is _ALWAYS_ executed even if
      inside <code> or <recoverCode> some new exceptions like RETURN,
      BREAK or QUIT will appear.
      Please note that when the following code is executed:
         BEGIN SEQUENCE
            <code>
         ALWAYS
            <alwaysCode>
         END
      (without RECOVER clause) then BREAK exception inside <code> is not
      recovered, <alwaysCode> is executed and then BREAK exception is
      passed to outer BEGIN SEQUENCE. This is the same semantic as
      used in TRY / [ CATCH ] / FINALLY / END
      Those of you who prefer to use TRY / CATCH / FINALLY / END instead
      of BEGIN SEQUENCE / RECOVER / ALWAYS / END can simply add to your
      source code:
         #command TRY               => BEGIN SEQUENCE
         #command CATCH [ oErr ]    => RECOVER [ USING <oErr> ]
      and:
         errorBlock( {|oErr| break( oErr ) } )
      Though instead of 'break( oErr )' I suggest to use some small function
      which will support some basic recovery/substitute operations like in
      default errorsys() and LockErrHandler() to not break existing code
      which may depends on the default behavior.
      If you want I can add direct support for TRY / CATCH / FINALLY / END
      but I'm not sure it's really necessary.
      Please note also that in Harbour ALWAYS code is execute even for QUIT
      excpetion.
      When <alwaysCode> is executed current exception is stored and restored
      when is finished. If new exception appears inside <alwaysCode> then
      restored exception depends on the priority in the following order:
         QUIT     // highest priority
         BREAK
         RETURN
      If both exceptions have the same priority and contain additional value
      (error object in BREAK or return value in RETURN) then the recently set
      one is restored. It's similar behavior to destructor code.

  * harbour/source/common/hbstr.c
    * moved one character length string table (hb_szAscii) from hvm.c
      to use it also in compiler and preprocessor

  * harbour/source/compiler/ppcomp.c
  * harbour/source/pp/ppcore.c
  * harbour/source/pp/pplib.c
    * tuned error messages to be more Clipper compatible
    % use static strings from hb_szAscii

  * harbour/source/rtl/alert.prg
    * use hb_gtInfo( GTI_FULLSCREEN ) to detect type of GT driver
    ! some minor fixes
      TOFIX: we have to also use GTI_ISCTWIN or add window allocation
             to standard GT drivers to be Clipper compatible when CTWIN
	     is used - In Clipper Tools ALERT() works in differ way then
	     the standard one. It creates separate window box to display
	     data, supports SETKEY(), etc. I'll think about adding some
	     extended support for ALERT() and similar operations (f.e.
	     separate debugger windows) to GT API so it will be also
	     possible to overload standard alert() command by GUI message
	     box in GTGUI and similar GT drivers.

  * harbour/source/rtl/binnumx.c
    ! fixed U2BIN() - wrong casting

    * general code cleanup: all strcpy() and strcat() replaced hb strn*()
      and hb_strn*(), sprintf() by snprintf(), etc.
      It fixed some possible buffer overflow but it's also possible that
      it will exploit some some hidden so far problems but I strongly
      prefer to know about them ASAP to fix them before final 1.0 release.
    ! fixed bug I introduce in codeblock falgs which disabled early macro
      evaluation in codeblocks.
    ! added missing protection against execution by bison destructor for
      used CBSTART token on syntax error.
    % use PP stringify logik added for FLEX support to remove all redundant
      spaces in stringified for early macro evaluation codeblocks and add
      spaces between operators if after preprocessing they were removed.
      Now we are supporting also some code which cannot be compiled by
      Clipper.
    % cleaned and improved the speed of printer redirecting in console code.
      Chen please check if CG still reports problems and if not ubdate
      TODO/TOFIX or inform me about them.
    * some cleanups in building process for different *nixes: MacOSX, SunOS,
      *BSD, etc.
    * removed not longer necessary (I hope) compiler flag to force default
      'char' type as signed. Now Harbour should work with signed and unsigned
      char without any problems. To other developers: please remember that
      when you are using 'char' as 8 bytes signed integer then it's a bug.
      Always explicitly use: 'signed char' in such case. On some platforms
      it's not possible to set default type for 'char' so if you hardcode
      that 'char' is signed or unsigned somewhere then code will not be
      portable. Chen if you will find a while to also rebuild Harbour with
      BCC and -K switch to make some tests with CG then I'll be thankful.

  + harbour/include/hbapicls.h
  * harbour/include/hbapi.h
    + added HB_IT_ENUM item
    + added collect member to HB_IT_POINTER structure for POINTER items
      inspected by GC
    * changed the order of HB_CODEBLOCK members to safe few bytes on
      alignment
    * removed counters from HB_CODEBLOCK and HB_BASEARRAY structure
    + added hb_xRefInc(), hb_xRefDec(), hb_xRefFree(), hb_xRefCount(),
      hb_xRefResize() functions. They are internal Harbour VM functions
      and covered by internal API macro. Should not be used by 3-rd
      party code because we may change them in the future or even remove.
    + added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
      functions. These are also internal function which corresponds to the
      above hb_x*() ones.
    - removed hb_arrayRelease() function. This function is not longer
      necessary and it should never be public function - it was implemented
      in very dangerous way.
    - removed hb_codeblockDelete() function.
    - removed hb_memvarValueDecGarbageRef()
    + added USHORT usLen parameter to hb_codeblockMacroNew() - when sets
      to non 0 value it informs that PCODE should be copied to dynamically
      allocated buffer.

      hb_vmInitSymbolGroup(), hb_vmExitSymbolGroup()
    * changed hb_vmProcessSymbols() to return address of register symbol
      table. For normal code it's the same address as given in parameter
      so it does not break backward binary compatibility.
    * changed symbol init macros to work correctly with modified address
      of symbol table

  * harbour/include/hbsetup.h
    * added support for HB_USE_PROFILER macro. Now profiler code is
      is disable in HVM by default

      table. For normal code it's the same address as given in parameter
      so it does not break backward binary compatibility.
    + use new code for operator overloading
    * changed FOR EACH to dynamically check iteration scope in
      hb_vmEnumNext()/hb_vmEnumPrev() and remove max number of iteration
      stored on HVM stack
    * temporary use hb_itemUnRefOnce() instead of hb_itemUnRefRefer() as
      workaround for possible GPF. I'd like Ryszard will chose the final
      version

  * harbour/source/vm/itemapi.c
    + added support for preallocating string buffer size
    + added hb_itemUnShareString() and hb_itemReSizeString()
    * updated string items to use counters allocated with each
      memory block by xh_xgrab()/hb_xalloc()
    * updated codeblock and array items to use GC reference counters
    + added GC inspected HB_IT_POINTER items.
    * generate RT error in hb_itemUnreOnce() for enumerator items
      out of scope
    + added hb_itemPutPtrGC()

  * harbour/source/vm/macro.c
    * use pDynSym->pSymbol->value.pFunPtr instead of pDynSym->pFunPtr

  * harbour/source/vm/maindllp.c
    * updated usage of hb_vmProcessSymbols()
    * added hb_vmProcessSymbolsExt()

  * harbour/source/vm/memvars.c
    + added hb_memvarGetItem()
    - removed hb_memvarValueDecGarbageRef()

  * harbour/source/vm/proc.c
    + added #include "hbapicls.h"

  * harbour/source/vm/pvalue.c
    * do not access stack structure directly but use hb_stack*()
      functions (macros)

  * harbour/source/vm/runner.c
    * synced with xHarbour

  * harbour/utils/hbtest/rt_misc.prg
   * added overloading "=" operator. Now "==" and "=" can be overloaded
     with different methods

   All names I used for new functions/macros can be changed. Please look at
   it and if you will some better propositions then we can use it.
   hb_vmProcessSymbolsExt() is added but not used yet.

    ! fixed PROW() updating to be Clipper compatible when row number
      exceed 16bit integer value

  * harbour/source/rtl/filesys.c
    ! fixed possible GPF when hb_fsCurDirBuff()

  * harbour/source/rtl/str.c
  * harbour/source/rtl/strzero.c
    * minor optimizations

  * harbour/source/rtl/strpeek.c
    ! fixed accessing the last character in STRPEEK() and STRPOKE()

  * harbour/include/hbgtinfo.ch
  * harbour/source/rtl/gtwin/gtwin.c
    + synced with recent xHarbour modifications

  * harbour/source/rtl/gtwvt/gtwvt.c
    * cleaned BCC warning

  * harbour/include/hbapi.h
  * harbour/source/vm/codebloc.c
    * declare BYTE * passed to hb_codeblockNew() as const

  * harbour/include/hbpcode.h
    ! fixed the PCODE numbers in PCODE description, 122 was repeated for
      two different PCODEs: HB_P_ONE and HB_P_MACROLIST

  * harbour/source/compiler/genc.c
    ! fixed hb_p_functionshort pcode size returned by genc function
    ! fixed double value presented in verbose genc mode for HB_P_PUSHDOUBLE
    ! fixed number of cases presented in verbose genc mode for HB_P_SWITCH

  * harbour/source/compiler/hbdead.c
    + added support for dead code elimination in functions which uses
      SWITCH ...; CASE ...; ...; END syntax

  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/hbfix.c
    ! fixed optimization for HB_P_PUSHLOCALNEAR and HB_P_POPLOCALNEAR.
      It was a long existing bug not reported so far because 0, 1 and 2
      PCODEs uses only one BYTE and bad PCODE tracing in hbfix.c didn't
      caused bad side effects as long as number of locals in function
      was smaller then 768. Now for functions HB_P_PUSHLOCAL and
      HB_P_POPLOCAL is used and later changed to NEAR version in hbfix.c
      if possible.

  * harbour/source/compiler/hbfix.c
    * join sequential jumps to optimize constructions like:
         while ...
            ...
            if ...
               exit
            endif
         enddo

  * harbour/source/compiler/hbdead.c
    * remove HB_P_END PCODE also at the and of function if is repeated
      just before, f.e. in code like (source/rtl/color53.prg):
         Function RADGRDEFCO( cColor )
            if isdefcolor()
               Return applydefau( cColor, "W/N", "W/N", "W+/N")
            Else
               Return applydefau( cColor, 3, 1, 4)
            endif
         Return nil
      Now such redundant constructions like above are fully stripped by
      compiler anyhow if someone has time and think is important then can
      clean also this .prg code.


  * harbour/include/Makefile
  * harbour/include/hbcomp.h
  + harbour/include/hbxvm.h
  * harbour/source/compiler/Makefile
  * harbour/source/compiler/cmdcheck.c
  * harbour/source/compiler/genc.c
  + harbour/source/compiler/gencc.c
  + harbour/source/compiler/hblbl.c
  * harbour/source/compiler/hbpcode.c
  * harbour/source/vm/hvm.c
    + added support for generating real C code not PCODE in .c files.
      Now with  -gc3 Harbour will generate .c files with real .c code
      which is later compiled to real machine code.
      I left PCODE only for code block definitions though it's also
      possible to have even code block compiled to machine code but
      we will have to add a flag to codeblock structure which will
      be checked at runtime and proper method of execution in EVAL
      will be chosen. If you think it's worth of afford then I can
      add it too in some spare time.
      The final binaries are noticable longer then the one which has
      only PCODE but they are faster. The speed improvement depends
      on type of operations. The pure Clipper code which does not
      execute any external time consuming C functions compiled with
      -gc3 is from 10% to 50% faster.
      The side effect of generating pure machine code is also harder
      recompilation but it does not mean that is impossible. If sth
      can be executed by some machines (virtual or hardware) then it
      can always be decompiled by definition.
      This modification opens door for farther optimization, f.e. when
      we will have fully working strong type support then we can add
      using native .c types.
      In fact this module is PCODE to .c translater not part of compiler
      and can be used as separate module to translate generated PCODE,
      f.e. .hrb files.
      Maybe in the future we will change the compiler to generate meta
      code not directly PCODE and it will be possible to make optimizations
      on this meta code which will depend on selected output type:
      VHM PCODE, C code, .NET code, etc. but at this moment adding support
      for .c compilation directly into compiler will make the compiler code
      too much complicated for me - IMHO it's better to invest time into
      clear separation to FRONT_END->REAL_COMPILER->BACK_END
      Please make test with your code. I rebuild whole Harbour code with
      -gc3 set in HB_FLAGS in harbour/config/rules.cf and all seems to
      work correctly. hbtest returns exactly the same results.
      I also made tests with my programs and they work correctly but
      I had to define actions for all PCODEs and it's possible that made
      some typos in some of them which are very seldom used so your tests
      will be very important.

    * use F macro extension to extract file name from given macros.
      It simplified some rules and allow to use vpath and differ file
      locations in GNU Makefiles
    * moved the BCC16 excpetion for C_RULE from global rules.cf to
      DOS bcc16.cf file
    * use mainstd library in MinGW build

  * harbour/include/hbapi.h
    + added two new functions: hb_winmainArgInit() and hb_winmainArgGet()
      to set/retrieve WinMain() parameters.
    + added hb_strMatchWildExact()

  * harbour/source/pp/ppcore.c
    * initialized variable to avoid compiler warning

  * harbour/source/rtl/console.c
    * cleaned comment

  * harbour/source/rtl/hbffind.c
    ! Fixed invalid handle error in Windows when file() fails
      (fix borrowed from xHarbour)

  * harbour/source/rtl/strmatch.c
    + added hb_strMatchWildExact()
    + added 3-rd parameter <lExact> to WildMatch() - when it's TRUE
      WildMatch() will check if given pattern cover the whole string.
      Without it it check if pattern is valid prefix only.

  * harbour/source/rtl/gtcrs/gtcrs.c
  * harbour/source/rtl/gtcrs/gtcrs.h
  * harbour/source/rtl/gtsln/mousesln.c
    * do not call Gpm_GetSnapshot() to avoid stupid message on stderr
      generated from GPM library - I lost the the hope that it will be
      fixed ;-)

  * harbour/source/rtl/gtpca/gtpca.c
    * use select() in *nixes for cursor position terminal feedback.

  * harbour/source/rtl/gtwin/gtwin.c
    * try to always allocate console when compiled without
      HB_NO_ALLOC_CONSOLE. It allow to use GTWIN also in real windows
      programs.

  + harbour/source/rtl/gtwvt/Makefile
  + harbour/source/rtl/gtwvt/gtwvt.c
  + harbour/source/rtl/gtwvt/gtwvt.h
    + added new GT driver GTWVT - the core of this driver it's Peter Ress
      work in xHarbour. In Harbour GTWVT contains only pure GT code without
      local to GTWVT xHarbour extensions and GTWVT contrib libraries.
      This extensions can be added but later but I want to keep them
      separated from the core GTWVT code and add them as upper level GT
      which can inherit from GTWVT. Just like I've implemented CTWIN.
      Please update non GNU make files and test this GT in Windows.
      The programs which want to use GTWVT should be compiled as standard
      Windows GUI programs. GTWVT replaces window console code.
      if you add to your code:
         proc GTSYS()
         request HB_GT_WIN
         request HB_GT_WVT
         return
      then the final binaries will be linked with both GT drivers and you
      can switch between them using //gt[:]<name> switch. F.e.:
         ./my_prog //gtwin
      or
         ./my_prog //gtwvt
      this feature works in all platforms.
      People who works in shell environment (*nixes, MSYS, DJGPP) and use
      hb* scripts does not have to use GTSYS() in source code but can simply
      use -gt<name> switch in hblnk and hbmk.

  * harbour/source/rtl/gtxwc/gtxwc.c
    * some minor cleanups and code formatting

  * harbour/source/vm/Makefile
  + harbour/source/vm/mainstd/Makefile
    * moved mainstd.c to separate mainstd library for MinGW32 build.
      Unfortunately MinGW always link main() function if it locate
      it in libraries and ignores WinMain() what effectively makes
      impossible to create Windows GUI programs if we have main() in
      VM library. People who are using MinGW and wants to create only
      pure console programs should now include mainstd library to linked
      library list.

  * harbour/source/vm/cmdarg.c
  * harbour/source/vm/mainwin.c
    + added two new functions: hb_winmainArgInit() and hb_winmainArgGet()
      to set/retrieve WinMain() parameters.
