    ! reverted fix for unnecessary -W2 warning:
         Function '...' does not end with RETURN statement
      in code like:
            func f(v)
            if v
               return "TRUE"
            else
               return "FALSE"
            endif
      Sorry but I had to make it because this fix was wrong and causes
      that code like:
            func f(v)
            if v
               ? v
            else
               return "FALSE"
            endif
      was compiled without any warnings but wrong PCODE was generated.
      In some spare time I'll try to implement valid RETURN detection,
      now simply add RETURN NIL at the end of such functions - it will
      be removed by dead code eliminator.
    ! fixed memory leak when more then one .prg file was given as compiler
      parameter
    + cleaned some code for future modifications

  * harbour/source/rdd/dbcmd.c
    ! use default RDD instead of current one in COPY TO and APPEND FROM

  * harbour/source/vm/classes.c

  * harbour/source/vm/itemapi.c

  + harbour/source/vm/hashes.c
  + harbour/source/vm/hashfunc.c
    + added hash items, f.e.:
         local h1 := {=>}, h2 := { "a"=>1.234, "b"=>2.345 }
         ? h2[ "a" ], h2[ "b ]
    + added support for DYNAMIC function declaration - it allow to define
      functions which are lately bound at runtime, f.e.:
         /*** t01.prg ***/
         dynamic func1
         proc main()
         local h:=__hrbload("t02.hrb")
         ? func1()
         return

         /*** t02.prg ***/
         func func1
         return "Hello!!!"

    % use new FUNCALL structure to hold EXTERNAL and DYNAMIC functions,
      it reduce memory usage, FUNCALL is much smaller then FUNCTION
    % use symbol scope bits when possible instead of making some linear scan
    + added new enumarator message: __ENUMKEY - it allow to access
      key value when hash item is base enumerator value, f.e.:
         proc main()
         local v, h:={"a"=>1.000,"b"=>2.000,"c"=>3.000}
         heval( h, { |k,v,i| qout( k, v, i ) } ); ?
         for each v in h
            ? v, "=>", v:__enumKey(), v:__enumValue(), v:__enumIndex(), ;
                       valtype(v:__enumBase())
            v += 0.123
         next
         ? ;heval( h, { |k,v,i| qout( k, v, i ) } )
         return
    + added C level hb_hash*() functions
    + added support for full HASH item cloning and updated array cloning
      to also clone nested hashes - please note that xHarbour does not do
      that, in xHarbour ACLONE() clones _ONLY_ nested arrays and HCLONE()
      _DOES_NOT_ clone _ANY_ nested items.

  * harbour/include/hbextern.ch
    + added hash functions HB_H*()
    * changed INET*() functions to HB_INET*()
    + added hash functions H*() and socket functions INET*() when
      HB_COMPAT_XHB is set

  * harbour/include/hbtypes.h
    + added missing HB_EXTERN_BEGIN / HB_EXTERN_END

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    ! added protection against automatic word concatenation in some cases
    ! fixed preprocessing expressions when match marker matches ';' token

  * harbour/source/rtl/Makefile
  + harbour/source/rtl/itemseri.c
    + added functions for item serialization: HB_SERIALIZE() and
      HB_DESERIALIZE() - these function are not binary compatible
      with xHarbour functions with the same names but make very
      similar job with the exception to serialization of codeblock
      and object variables - Harbour does not allow to serialize
      codeblocks and serialize objects as arrays.
      In most cases these functions can replace the xHarbour ones
    + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
      by HB_COMPAT_XHB macro - this functions are only for compatibility
      with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
      dummy function which returns first parameter and HB_DESERIALNEXT()
      is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
      use them.

  * harbour/source/rtl/hbinet.c
    * changed INET*() functions to HB_INET*() and enable them for default
      build
    + added INET*() functions wrappers covered by HB_COMPAT_XHB macro

  * harbour/source/rtl/hbrandom.c
    + added HB_RANDOMINT() - xHarbour compatible

  * harbour/source/rtl/len.c
    + added support for HASHes

  * harbour/source/rtl/valtype.c
    + added support for HASHes
    + added set of HB_IS*() functions - they are a little bit faster then
      calling VALTYPE( v ) == <cVal>
    - removed HB_ISBYREF() - this function cannot longer work, it was using
      a Clipper incompatible anomalies in passing variables by reference I
      fixed so it has to stop to work. If it will be realy necessary to
      implement HB_ISBYREF() function then please inform me - it will have
      to be done at compiler level or with some much deeper HVM stack
      checking.

  * harbour/source/vm/extend.c
    ! fixed hb_extIsArray() and hb_extIsObject() to work well with
      parameters passed by reference.
      Please note that now hb_extIsArray() return TRUE only for pure arrays
      not object values.

  + harbour/contrib/tip/tip.ch
  + harbour/contrib/tip/url.prg
  + harbour/contrib/tip/utils.c
    + added TIP library - code borrowed from xHarbour



   Please test - a lot of above code is not well tested, also some peaces
   were written over year ago for different things (f.e. serialization for
   NETRDD) and now I collected them and committed.
   The TIP library was not tested at all. It can be compiled but I cannot
   say if it works - I hope that people familiar with it can make necessary
   test and fixes.
   It's also not the final version of low level HASH item code. I'm working
   on more efficient structure which uses binary tries but I cannot say when
   I'll finish it (maybe in this weekend or maybe in next year) so I committed
   working version now even if I'm not happy with overall performance (BTW
   not worser then in xHarbour)

* harbour/include/hbexpra.c
    * emulate xHarbour HB_ENUMINDEX() inside FOR EACH loop when
      HB_COMPAT_XHB macro is set
      It's only for compatibility - I strongly suggest to use
            <unumvar>:__enumIndex()
      which is more flexible and allow to chose the enumerator
      variable not only the one from last loop

  * harbour/include/hbexprb.c
    * added comment removed from hbexpra.c

  * harbour/source/compiler/hbmain.c
    ! fixed GPF which can appear when -b option is used in line numbering
      inside codeblocks

      Now new compiler library is created.
      There are some things which can be improved and cleaned yet
      but it's enough to create single binaries with compiler+HVM+RTLs.
      I updated non GNU make files but I cannot tested the modifications
      - please check and fix me if necessary

    ! fixed Harbour support for accessing string characters with array
      index operators []
    + added support for #define HB_COMPAT_XHB - it's disabled by default.
      When set it enables some of xHarbour features like negative array
      indexes calculated from tail, accessing string characters with []
      operators (warning it's not compatible with default Harbour version
      enabled by -ks during compilation and //flags:s at runtime - in
      xHarbour compatibility mode "ABC"[2] returns "B" when in Harbour 66)
      and some other minor features.

  * harbour/source/compiler/cmdcheck.c
    * added support for optional setting C output type in -go switch
      Now it accepts optional digit [0123] after -go in the same way
      as -gc, f.e.: -go3

  * harbour/source/compiler/harbour.c
    * call hb_compExprLstDealloc() only when errors appeared during
      compilation - it disable automatic freeing all allocated expressions
      in clean compilation. I make it intentionally for easier detecting
      problems one some expressions are not freed. So far the final cleanup
      code always deallocated expressions what can hide some real bugs.

  * harbour/source/vm/hvm.c
    ! fixed very serious bug in HVM closing. The s_uiActionRequest flag
      was not cleared before hb_rddShutDown() so when RDD buffers were
      hot and flushing required some PCODE evaluation (f.e. index KEY
      or FOR expression) then they were not properly evaluated.

      push context - Clipper compatible behavior, see:
         x:=10
         f(y:=iif(.t.,@x,))
         ? x, y
         func f(x)
         x+=100
         return nil

  * harbour/include/hbver.h
  * harbour/source/common/hbver.c
    * changed status to "devel"

  * harbour/source/common/expropt2.c
    * disabled setting NIL when iif(.t.,,sth()) is optimized to avoid
      warning when iif() is used as statement - to fix number of parameters
      passed to function in code like f(iif(.t.,,sth())) we will need a
      little bit deeper modification

  * harbour/source/compiler/complex.c
    * added hack for potential problems caused by WITH OBJECT syntax, f.e.
      in code like:
         proc p(obj,x)
         case:=myCaseClass():new()
         retu:=myCaseClass():new()
         WITH OBJECT obj
            do case
               case x==nil
               case:value()
               case:action()
                  retu:sth()
            end
         END
         case:action()
         retu:sth()
         return
      case:action(), case:value(), retu:sth() can means two different things
      and compiler cannot guess which one should use. It cannot be fixed
      because it's caused by bad WITH OBJECT syntax. In xHarbour constractions
      like case:value() or retu:sth() are always used as in  WITH OBJECT
      context what is not Clipper compatible. I do not want to introduce
      such limitations. We have two choices: change WITH OBJECT syntax or
      add some hack to "hide" the problem a little bit. Now I intorduce
      ugly hack which check number of spaces between ':' so
         case :action()
      is compiled as case condition using WITH OBJECT message and
      case:action() as sending message to object in case variable

  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
    + added support for passing base value to FOR EACH by reference.

  * harbour/source/vm/arrays.c
    * use hb_itemMoveRef() in AINS()/ADEL() to avoid creation of cyclic
      reference chains

  * harbour/source/vm/debug.c
  * harbour/source/vm/memvars.c
    * use hb_itemCopyToRef() to avoid creation of cyclic reference chains

  * harbour/source/vm/classes.c
  * harbour/source/vm/hvm.c
    * use hb_itemMoveToRef() to avoid creation of cyclic reference chains
    + added support for for writable string enumerators, f.e.:
         proc main()
         local s, c
         s:="abcdefghijklmnopqrst"
         for each c in @s
            if c$"aeio"
               c:="*"
            endif
         next
         ? s // "*bcd*fgh*jklmn*pqrst"
         return

    - removed compiler switches and macros for old HB_INLINE() syntax - it
      was not supported after last months modifications. Only:
         HB_INLINE([params,...]) { C code }
      is supported.
    ! fixed passing parameters by reference in IIF() statement and macro
      compiler. The following valid Clipper code:

      was not supported
    ! do not allow to use references or empty expressions in expression list
      AFAIK it's Clipper compatible. If I'm wrong then please fix me but
      Clipper allows to use references only as function arguments, 2-nd and
      3-rd IIF() argument and as directly created array items ( {...@var...} )
      DO ... WITH ... is a special case of function call.
    ! Changed grammar rules to accept only Clipper compatible parameters.
    ! fixed typo in macro name in hb_memvarNewParameter() function.
    * use HB_FUNC_EXEC(...) instead of HB_FUNCNAME(...)()

* harbour/include/hbcompdf.h
     + added comment

  * harbour/include/hbexpra.c
     * change expression type for <exp> = <exp> from HB_EO_EQUAL
       to HB_EO_ASSIGN in hb_compExprGenStatement() function so
       later we can safely make all optimization in hb_compExprUseEqual()
       during reduce process - optimization only when PCODE is generated
       is too late and causes that expressions like:
         iif( 1 = 1, <exp>, <exp> )
       are not reduces (Clipper reduce them)
     * do not execute hb_compFunCallCheck() in hb_compExprNewFunCall()
       to avoid repeating the same error message in hb_compExprUseFunCall()

  * harbour/include/hbexprb.c
     * enabled reduction for hb_compExprUseEqual() and generate errors
       when it's used as statement

  * harbour/source/common/expropt2.c
     * added some missing reductions for expressions like: NIL == NIL

  * harbour/source/common/reserved.c
     % very basic optimization: use binary search instead of linear
       scanning for reserved words and shortcuts - it gives noticeable
       speed improvement in macro compiler

  * harbour/source/compiler/complex.c
     * changed the order of special keywords to keep alphabetic sorting

  * harbour/source/compiler/harbour.c
     % some minor optimizations in aliased expressions
     ! added protection in hb_compIsJump() to avoid possible problems
       when this function is executed after replacing some code with

  * harbour/source/compiler/hbfix.c

    * a little bit more simple implementation of passing optional arguments
      and simplified some code. Now they can be used in any place in argument
      list (also repeated). It's also possible to create arrays using "..."
      as array element(s), f.e.: func f(...); return { "{", ..., "}" }
      If you think it will be usable then I can also add support for accessing
      array items with optional parameters, f.e.: ? a[ ... ]
      so it can be used in the same context as xbase++ like macro lists
      but for this I will need new PCODE so I'd like to hear your opinion
      ASAP - I'm closing any extensions today.

    * do not generate HB_P_FUNCPTR - it's not longer necessary
    + added optimization for <exp> + 1, <exp> - 1 - disabled by default
      because it changes error messages in hbtest, code like NIL + 1
      generates 'argument error ++' instead of 'argument error +'. I'd like
      you will decide what you prefer - faster code or strict Clipper error
      messaged.

  * harbour/source/common/expropt2.c
    + added optimizations for <num> + <date>
    + added ooptimizations for <exp> + 0, 0 + <exp>, <exp> - 0
      This is also sth what may interact with operators overloading in object
      system. When we will have strong typing then we should think about an
      option which will optionally disable some optimizations - someone may
      want to define arithmetic where <obj> + 0 gives differ then <obj>

      HB_P_DUPLICATE -> HB_P_JUMP[TRUFALES] -> ...
      In fact it should not be done here but because we do not have
      any metacode level where such optimizations should be done and
      PCODE is generated online then it will have to be here. Maybe
      in the future we will add metacode.

  * harbour/source/rdd/dbcmd.c

  * harbour/source/vm/macro.c
    * removed hb_compMemvarCheck() - this function was not dooing
      anything - only slows the TYPE() by calling hb_dynsymFind()
      one or two times.
    + added TODO note: memvars create by TYPE() have PUBLIC scope
      in Clipper. Clipper also always tries to evaluate valid expressions
      inside TYPE even if the contain UDF. UDF only stops evaluation
      so:
         TYPE( "(val:=1) + f() + (val2:=2)" )
      creates in clipper public variable VAL but not VAL2.

      ! fixed GPF traps when too long string or codeblock is generatd
      + added support for 16MB codeblocks and strings
      ! removed macrocompiler limitation for jumps range
      ! fixed GPF when more then 255 local variables is used and added
        support for 2^15 locals
      ! removed all strtok() functions
      % added optimization for all +=, -=, *=, %=, ^=, **= operations
        when left side of expression is variable or array item
      % added optimization for all +=, -=, *=, %=, ^=, **= operations
        when left side of expression is object method and updated ++, --
        for new code. It's still disabled until we will not add support
        for late evaluated reference items to HVM
      ! fixed a[++i]++ and similar operations (a[++i]*=2, ...). Now ++i is
        executed only once. It's not Clipper compatible but it was in
        TODO note in source code. It can be disabled by -kc option
      * finished support to xHarbour like #pragma TEXTHIDDEN(1)
      ! fixed local add int optimization when PARAMETERS used after
        optimization changed local variable number over 255
      ! fixed GPF trap when in HB_P_<op>EQ PCODEs when executed for
        direct values
      * others
    ! fixed problems reported by Chen
    * optimized strtran(), left(), right() to not create new string copy
      when the same value is returned

      yy prefix.
    ! do not use bison destructors for expressions. Internal bison logic
      cannot properly detect if expression was used or not in some of our
      grammar rules and it's possible that some expressions will not be freed
      and some other freed twice.
    ! added protection against multiple destructors execution for CBSTART
      and LITERAL tokens
    * added small garbage collector for deallocating expressions which were
      not freed (such situation can happen in syntax errors)
    % some optimizations in used structures to reduce their sizes

    * hide HB_MACRO internal definitions in hbapi.h when HB_MACRO_SUPPORT
      is not set
    These modifications should help in future compiler and macro compiler
    integration into single binary.

    + added clipper compatible error message in unclosed structures
      In general we should cleanup rules to make error reporting more
      user friendly and Clipper compatible
    % eliminated unnecessary allocations
    + added int mode member to common part of HB_COMP and HB_MACRO
      structure. It's initialized to HB_MODE_MACRO or HB_MODE_COMPILER
    + add TOFIX note about memory leaks in cParamTypes and pParamClasses
      members of COMDECLARED structure. It's a part of unfinished strong
      typing code. I do not know what Ryszard plan to do with it so I'm
      leaving it as is. The part of strong typing which were operating
      on emulated HVM stack has been removed.
    * removed static variables from genjava.c. Also gencli.c and genobj32.c
      should be fixed but this will not make this code working so I haven't
      touched it.
    * changed 3-rd parameter of hb_compIdentifierNew() from BOOL to int.
      Now it can have the following values: HB_IDENT_STATIC, HB_IDENT_FREE,
      HB_IDENT_COPY. This modification will allow in the future using common
      for static and dynamic symbol hash table without additional source code
      changes. I also plan to use identifier hash table in PP the reduce
      number of memory allocations and speed-up preprocessing by using
      second level hashing for hash keys.

      expression to HB_ET_ALIAS.

  * harbour/source/macro/macro.y
    ! fixed using prefix&macro-> and &macro.sufix-> when macro cannot be
      substituted by compiler, f.e.:
         M->v := NIL

         M->v := "v"
         M->v1:= "data"

      What should cause silent clean application close.
      Please keep it in mind making future modifications and do not
      introduce and exit() function call.
    + added support for \x<hex> and \<oct> quoting in extended strings
      (just like in C). Warning !!!. Embedded 0 bytes are supported by
      PP, lexer and expression optimizer but not by bison. To make them
      working it will be necessary to change Literal terminal symbol
      holder and add length field in bison rules and also change the hash
      table used to hold identifiers, literals and macros to store and use
      real string length. If someone will try to use strings with embedded
      0 now then they will be cut but nothing worser should happen.

    * changed the internal compiler API to be MT safe.
      All global and static non constant variables replaced by
      HB_COMP structure which have all compiler context settings.
      It's possible to allocate simultaneously many compiler contexts
      and compile code. Only constant/read only variables are shared.
      In macro compiler HB_COMP is replaced by HB_MACRO.
      In source code I everywhere used to macros: HB_COMP_DECL and
      HB_COMP_PARAM which are equivalents of old HB_MACRO_DECL and
      HB_MACRO_PARAM definitions.
      We will only have to change compiler FATAL errors support to
      not execute exit() for non batch systems.
    * make macro compiler fully MT safe
    * removed not longer used definitions and variables
    ! add direct accessing to PP line number information - it fixes missing
      line numbers reported recently
    ! added generating .ppo files when tokens are teken directly by compiler
      - it fixes empty .ppo file problem
    ! clear hb_stack internall variables after removing hb_stack to avoid
      possible GPF if application still works and try to access unexsiting
      hb_stack
    ! do not allocate new memory block when final FM statistic report is
      generated - it fixes problem with GPF when application compiled with
      FM statistic exits and CLIPPER envvar is set.
    ! fixed memory leak hb_cmdargCheck()
    ! added to harbour.y symbol destructors - it should fixes memory leaks
      in syntax errors but it uses quite new bison feature which is not
      fully supported yet. Unfortunately it's also not MT safe and the
      destructors implementation in 1.875c does not respect %parse-param.
      Bison documentation says that it should so I hope it will be fixed
      soon (or maybe even already is in the newest bison versions) before
      I'll add multi context compilation support. If not then I will have
      to add some workaround. I can pass compiler context pointer inside
      YYSTYPE using hack in a lexer but it will force really huge number
      modifications in existing bison rules so probably it will be much
      easier to fix bison or write a small tool to update generated parser.
    * other modifications - the total size of patch is nearly 1MB and
      detail description will have to take me few days.

    PP, new lexer and most of grammar parser should be MT safe. Now we should
    update all compiler functions to pass pointer to HB_COMP data structure
    where we should all current global variables. This structure as first
    member should have HB_CMPCOMMON structure which will hold common to
    compiler and macro compiler data. Ryszard I think you are the best person
    to define this structure.

    We have new lexer which is MT safe but please note that it has to be
    extensively tested so I would like to ask everybody to compile as much
    as possible different code and check if the final programs work as
    expected. Working on new code I removed some limitations existing in
    FLEX though not all. At the beginning I tried to replicate the exact
    FLEX behavior but I've found that in few places it does not work as
    it should so I begin to encode rules in a way which remove some
    limitations. In fact now it's much easier to control some things.
    I kept the FLEX code working and made all necessary modifications
    so it still can be used but keeping FLEX working cost us IMHO too
    much. It's not possible to introduce some improvements to grammar
    parser. All identifiers, keyword and macros returned by new lexer
    are converted to upper letters, do not have to be freed by hb_xfree()
    and is guarantied that will be always accessible. So from grammar file
    we can remove all hb_compIdentifierNew( hb_strupr($1), TRUE ) what
    should give noticeable speed improvement but will break the FLEX code.
    Ryszard and other you will have to decide if we will support FLEX in
    the future. We can also clean the code and remove most of other
    redundant hb_strupr() and hb_strdup() used in many places. BTW only
    one terminal symbol can be returned with lower letters: DOIDENT
    and I make it intentionally so it's possible to use:
         DO prog1 WITH "sth"
    on case sensitive file systems so this symbol should be cloned in
    upper cases as function symbol but used without modification as
    file name. It's current behavior but I'm not sure you will want
    to keep it. Maybe compiler switch to always convert file names
    created from
         DO <id> [WITH <params,...>]
    to lower cases will be better. Please think about it.

* harbour/include/hbapi.h

  * harbour/source/pp/ppcore.c
  * harbour/source/pp/ppgen.c
  * harbour/source/pp/pplib.c
    * make HB_PP_TOKEN structure public for other code and changed
      public PP API to not force including static rules by programs
      which does not need them.
    + added basic API for using PP as lexer
    * divided HB_PP_TOKEN_MACRO to HB_PP_TOKEN_MACROVAR and
      HB_PP_TOKEN_MACROTEXT and mark
         [<keyword>][&<keyword>[.[<nextidchars>]]]+
      as HB_PP_TOKEN_MACROTEXT not pair HB_PP_TOKEN_KEYWORD and
      HB_PP_TOKEN_MACRO
      It allows easier integration PP as (macro)compiler lexer and
      fixes preprocessing [<keyword>][&<keyword>[.[<nextidchars>]]]+
      in some patterns.

  * harbour/utils/hbtest/Makefile
    + added PP library to linked library list

  * harbour/source/macro/macro.y
    + added seaport to use PP as lexer. It's disabled by default and
      can be enabled using by defining HB_PP_MACROLEX. It eliminates
      using FLEX or SIMPLEX lexer in macro compiler. Now it emulates
      the behavior of FLEX lexer because I wanted to minimize the
      modification but in fact because parsed token are freed when
      macro compiler finish its job then we can resolve RT memory
      leaks which apear during parsing wrong expressions. It will be
      enough to drop allocating memory for new terminal symbols and
      using them as is like in compiler. It will also quite nice
      simplify include/hbexpr*.c code and will allow to move some
      functions to COMMON library. I want to make also pure compiler
      code MT safe so I will have to add passing pointer to a structure
      with compiler context just like in macro compiler. It means that
      if we define a structure which will be common to compiler and macro
      compiler with local (not common) data stored in other structure for
      which will will keep only a pointer then we will be able to move most
      of include/hbexpr*.c code to common library. But I do not want to
      make farther modification without consultation without Ryszard.
      Also to make PP default lexer some farther modifications should
      be done in core PP code and include/hbexpr*.c files to not reduce
      the speed. Now using HB_PP_MACROLEX for sure will have to cause
      speed reduction in macro compiler. But if we make necessary
      modifications then we should keep at least the same speed or
      probably reach noticeable better results.

* harbour/include/hbdefs.h
    * use extern "C" as default for HB_FUNC() declaration in C++ mode.
      I know that this modification will interact with binary compatibility
      but current state is worser because we were not binary compatible
      between C and C++ mode. Now the problem should gone with some
      reasonable for me cost. If your compiler uses the same ABI for C and
      C++ mode then the backward binary compatibility problem can be resolved
      by small tools which can strip C++ decoration from binary libraries or
      maybe even linker has necessary switches to ignore them.

  * harbour/source/compiler/harbour.c
    * extend init statics name with the number of used static variables
    * formatting

  * harbour/source/compiler/hbusage.c
    + added my name to developers list - I hope that there is enough
      of my code in Harbour (BTW for quite long time) ;-)

  * harbour/source/rdd/dbcmd.c
    - removed DBF2TEXT() function

  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
    * generate RT error when someone tries to create DBF with memo fields
      without MEMO RDD linked.

  * harbour/source/rtl/errorapi.c
    * replace all hb_vmDo() with hb_vmSend()

  * harbour/source/rtl/math.c

    - removed hb_arrayRelease() function.
    * changed hb_arrayReleaseGarbage() to be safe for recursive call
    * updated to use GC counters

  * harbour/source/vm/arrayshb.c
    * use stack function/macros instead of direct accessing HB_STACK members

  * harbour/source/vm/asort.c
    * removed unused HB_ASORT_OPT_ITEMCOPY

  * harbour/source/vm/classes.c
    * added class code from HVM
    % added fast overloaded operator detection and execution
    + added hb_objHasOperator(), hb_objOperatorCall()
    + added separated overloading of "=" and "==" operators
    * operate on PHB_SYMB not PHB_FUNC - support for pure PCODE function
      without any machine code
    * use stack function/macros instead of direct accessing HB_STACK members
    * separated profiler code
    * some code cleaning

  * harbour/source/vm/codebloc.c
    + added USHORT usLen parameter to hb_codeblockMacroNew() - when sets
      to non 0 value it informs that PCODE should be copied to dynamically
      allocated buffer.
    * updated to use GC counters
    - removed hb_codeblockDelete() function.
    * changed hb_codeblockDeleteGarbage() to be safe for recursive call
    - removed restoring statics base in hb_codeblockEvaluate()

  * harbour/source/vm/debug.c
    * cleaned and optimized some code

  * harbour/source/vm/dynlibhb.c
    + added support for loading and unloading dynamic libraries with PCODE
    + added support for dynamic libraries in Linux (.so)

  * harbour/source/vm/fm.c
    + 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.

  * harbour/source/vm/garbage.c
    + added hb_gcRefInc(), hb_gcRefDec(), hb_gcRefFree(), hb_gcRefCount()
      functions. These are also internal function which corresponds to the
      above hb_x*() ones.
    * changed Step 3 of GC pass and execution of clean-up function to be
      safe for recursive calls and additional activity.
      Ryszard see my note and s_pDeletedBlock

      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.
    + 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/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.

   + source/common/hbdate.c
   + tests/ddate.prg
   + tests/switch.prg
      +added support for DATE type constants in the following format:
         0dYYYYMMDD
      for example (see tests/ddate.prg for more):
      IF( dDate > 0d20051112 )

      +added support for SWITCH command (see tests/switch.prg)
         SWITCH <expr>
         CASE <integer_expression>
            ...
            [EXIT]

            [EXIT]
         [OTHERWISE]
            ...
         END

   Notice:
      - Integer and string expressions can be mixed in a single
        SWITCH command with no runtime errors;
      - CASE expression have to be resolved at compile time and
        the result has to be either an integer or string constant
      - if there is no EXIT statement then next CASE is executed
        (or OTHERWISE for the last CASE)
      For example:
      CASE 1+32+2*4
      CASE CHR(64)
      CASE ASC('A')
      CASE "A"+CHR(13)

   Notice:
      The above changes apply only to FLEX version!
