  + 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/Makefile
  + harbour/contrib/tip/Changelog
  + harbour/contrib/tip/Makefile
  + harbour/contrib/tip/atokens.c
  + harbour/contrib/tip/base64x.c
  + harbour/contrib/tip/cgi.prg

  + harbour/contrib/tip/smtpcln.prg
  + 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/hbapi.h
  * harbour/include/hbapiitm.h
  * harbour/source/vm/garbage.c
  * harbour/source/vm/extend.c
  * harbour/source/vm/itemapi.c
    + added hb_gcFunc(), hb_parptrGC(), hb_itemGetPtrGC()
      hb_parptrGC() and hb_itemGetPtrGC() uses GC cleanup function address
      to validate if pointer item points to expected memory block type

  * harbour/source/common/hbhash.c
  * harbour/source/compiler/hbident.c
    * formatting and minor modifications

  * harbour/source/pp/pplib.c
  * harbour/source/pp/pplib2.c
    * use hb_parptrGC() to be sure that given pointer item points
      to PP structure

  + harbour/include/hbregex.h
  + harbour/source/rtl/hbregex.c
  * harbour/source/rtl/Makefile
  * harbour/common.mak
    + added support for regular expressions. Now it's enabled by default
      only in *nixes (POSIX regex) and BCC 5.5 (PCRE regex). Setting
      HB_PCRE_REGEX macro enables Perl-Compatible Regular Expressions
      and HB_POSIX_REGEX - POSIX regular expressions. In xHarbour regex
      support is enabled for all builds because PCRE source code is stored
      in CVS. If you will want we can make the same.
    + the following C functions are available:
      hb_regexCompile(), hb_regexGet(), hb_regexFree(), hb_regexMatch()
    + the following PGR functions are available:
      HB_REGEXCOMP(), HB_ISREGEX(), HB_ATX(), HB_REGEX(), HB_REGEXMATCH(),
      HB_REGEXSPLIT(), HB_REGEXATX(), HB_REGEXALL()
      They are working in similar way to the ones in xHarbour with the
      exception to some bug fixes and form of compiled regular expression.
      In Harbour it's pointer item for which HB_ISREGEX() returns TRUE when
      in xHarbour it's binary string.

  * harbour/source/rdd/dbfcdx/dbfcdx1.c
  * harbour/source/rdd/dbfntx/dbfntx1.c
    * enabled code to seek in index using regular expressions
      (DBOI_SKIPREGEX[BACK])

      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

      optimizer
    * chaned a little bit WITHOBJECT syntax.
      Now WITHOBJECT somefunc(); END is not silently ignored and call

      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.

    ! 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.

  * harbour/source/vm/macro.c

  * harbour/include/hbexprb.c
    ! use HB_P_DUPLUNREF instead of HB_P_DUPLICATE when assign is used in

         f(y:=iif(.t.,@x,))
         ? x, y
         func f(x)

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

  * harbour/source/common/expropt2.c

      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

               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

  * harbour/source/vm/classes.c

      is supported.
    ! fixed passing parameters by reference in IIF() statement and macro

      was not supported
    ! do not allow to use references or empty expressions in expression list

      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.

     + 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

       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

      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.

      you will decide what you prefer - faster code or strict Clipper error
      messaged.

  * harbour/source/common/expropt2.c
    + added optimizations for <num> + <date>

      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

      source code:
      ! 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

    * 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.

    + added hb_comp prefix to grammar/lexer compiler public functions to
      reduce possible conflict with 3-rd party code which may use default
      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

      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.

  * harbour/source/common/expropt1.c
  * harbour/source/common/expropt2.c
    * changed HB_MACRO_SUPPORT to HB_COMMON_SUPPORT to automatically detect
      possible conflicts between compiler and macro compiler
    ! removed first detected conflict which existed for long time
    + added hb_compExprMacroAsAlias() function to convert HB_ET_VARIABLE
      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
         x := "&v.1->fld"
         M->v := "v"
         M->v1:= "data"
         ? &x
    ! fixed memory leak in macro substituted expression compilation

  * harbour/source/vm/macro.c
    ! fixed initialization of some HB_MACRO members
    ! fixed value returned for type("&V->F") when alias does not exist
    - removed not longer used hb_comp_bShortCuts global variable

      fatal errors does not interrupt application but only sets
         HB_COMP_PARAM->fExit = TRUE;
      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.

      with only his own rules we are not forcing linking static tables
      which are quite huge (over 100kb)

         __PPADDRULE(), __PREPROCESS(), __PP_FREE()
      Please note that using this function is not MT safe. They should
      work like with old PP code. Using any of this function automatically
      forces linking __PP_STDRULES

    + New PP code written from scratch. It works in similar way to
      Clipper PP even the error codes are replicated. The code is MT
      safe does not have any limitation on size of preprocessed code,
      line, etc. It's also Clipper compatible lexer. It means that
      we do not longer need FLEX or SIMPLEX which can be replaced
      by new PP after some small modifications. Anyhow I haven't
      decided to make it myself. I would like to agree with with the
      rest of developers. I will be very happy if such modifications
      will be done by someone else, Ryszard?
      Meanwhile I current PP join on output the line tokens and give
      the string line to FLEX/SIMPLEX. It does not have any sense and
      all FLEX/SIMPLEX limitations are still existing. Ryszard, even
      if we keep it then I hope you can remove at least FLEX line buffer
      and use the one returned from PP.
      Because string tokens in parsed line are converted to text which is
      later once again decoded to tokens by FLEX I had to introduce new
      string format which supports embedded string delimiters. I chose
      modified version of xHarbour extension with escaped strings e"<sting>"
      so now FLEX understand such strings and decode them like C escaped
      strings. It means that you can use them also in the .prg code f.e.:
         outstd( e"Hello\n\rWorld" )
      The new PP is also noticeable faster. You should see the difference
      compiling long files. The build in PP rules are generated automatically
      by ppgen program created from source/pp/ppgen.c
      I had to add to GNU source/pp/Makefile these two lines:
         pptable.c : ppgen$(EXE_EXT)
         	./ppgen$(EXE_EXT) $(TOP)$(ROOT)include/hbstdgen.ch -opptable.c -q
      Sth like that will have to be done also in non GNU make system.
      Now Harbour can be compiled only using GNU make.
      Marek can you update non GNU make files? I would like to leave this
      modification to you or other developers who can test it.
      It was quite big modification and I do not believe that I haven't
      make any mistakes but I hope that in few weeks I'll fix any reported
      bugs and it will resolve any PP problems.
      TODO:
         * error messages
           create one common list of errors and warnings and keep it
           in common library. PP and compiler can still generate different
           errors with the same number. It can be confusing for the users
           and hard to document and add i18n translations.
           If possible we should also try to keep Clipper error numbers.
           In new PP code I added Clipper error numbers but I cannot use
           them until compiler code is not updated.
           We should aslo remove the ctype passed to error functions and
           hack with first character in warning messages and use only
           error number. The codes from 1000 to 1999 should be warnings
           where range 1000:1099 is activated by -w, 1100:1199 by -w1,
           1200:1299 by -w2, etc. 2000:2999 are errors and 3000:3999
           fatal errors. All compiler functions which generate an error
           should expect that error function will not stop the compiler
           but return and cleanly finished their job. It's necessary for
           MT support in compiler and making compiler part of some other
           programs which may still work and compile different source code.
         * FLEX/SIMPLEX
           remove them at all and add some final pass to PP to create
           more precise tokens for grammar parser or at least add better
           integration to remove some redundant code and existing limits.
         * hb_inLine() support - it's broken in new PP but as I can see
           it was never working correctly. I can add a hack to PP to support
           hb_inLine() but I'm not sure it's worth to do. Maybe in few days.

  + harbour/include/std.ch
    + added new std.ch. It was created without using Clipper's std.ch.
      It's quite possible that some rules are wrong and should be fixed
      so please help. Anyhow I created a set of programs based on new PP
      code generating all possible combinations of different commands I
      collected from different source code, documentation and match patterns
      of rules I was adding to new std.ch and then I was comparing .ppo
      files generated by Clipper and Harbour so I do not expect any bigger
      problems then some minor typos. I had to introduce some modifications
      in spacing as workaround for FLEX/SIMPLEX which cannot properly decode
      text preprocessed by Clipper after stringify.

  * harbour/utils/hbpptest/pretest.prg
    * updated for new PP
      It reports 16 wrong translations but some of them are valid
      and some others are caused by escaped string e"..." (one of hack
      for FLEX/SIMPLEX support)
      I also had to remove all spaces in comparison the results
      because they were not Clipper ocmpatible at all. Ryszard please
      look at it.

Ryszard Glab
64509ea871 + added support for passing methods as macro 
eg:
         o:&send()
         o:&send.end()
         o:&(expr)()
         o:&var++
         o:&var := 0
         o:&(expr)++
         WITH OBJECT obj
            ++:&var
            :&var += :&(var2+"oo")
         END

   NOTICE:
   For simple assigments (=,:=), compound assignments (+=,-=,*=,/=)
   and for pre/post increment operators( ++,--) the macro should
   evaluate to a symbol that starts with underscore '_'.
     To access a variable the macro should evaluate to a symbol
   with no '_' char.

  * harbour/source/vm/classes.c
    * restored the original 3-rd parameter in  hb_clsAdd to void(void) -

    + 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.
    * moved all classes/object functions to separate file: hbapicls.h
    + added hb_retptrGC()
    + added internal function hb_memvarGetItem()

  * harbour/include/hbapiitm.h
    - removed hb_itemForwardValue() and added macro which translates
      hb_itemForwardValue() to hb_itemMove()
    + added hb_itemUnShareString() and hb_itemReSizeString() functions

    + added hb_vmProcessSymbolsExt(), hb_vmRegisterSymbols(),
      hb_vmFreeSymbols(), hb_vmBeginSymbolGroup(),
      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
    * commented out HB_ASORT_OPT_ITEMCOPY - it's not longer used - see note.

  * harbour/include/hbstack.h
    * added missing parenthesis in hb_stackItem() macro

  * harbour/include/hbtypes.h
    * updated VM_PROCESS_DLL_SYMBOLS definition

      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
    + added GC inspected HB_IT_POINTER items.

   * 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.

  + harbour/contrib/libct/ctwfunc.c
  + harbour/contrib/libct/ctwin.c
  + harbour/contrib/libct/ctwin.h
    * added CT3 like Window System - it's a GT driver which inherits
      from the existing one and adds CTW functionality

  * harbour/contrib/libct/screen1.c
    * updated for GTAPI modifications

  * harbour/contrib/libnf/Makefile
  * harbour/contrib/libnf/chdir.c
  * harbour/contrib/libnf/mkdir.c

  * harbour/include/Makefile
    * added new header files

  + harbour/include/hbgtinfo.ch
    + added GTI_* defintions for hb_gtInfo() function.
      This function works in similar way to dbInfo() in RDD.
      The GTI_* definitions are taken from xHarbour "as is" and
      they should be cleaned - not all functionality are supported
      in Harbour and some others should be implemented in differ
      way then in xHarbour.

  + harbour/include/hbgtcore.h
  * harbour/include/hbapigt.h
    * new GTAPI
      hbgtcore.h file should not be included by user code
      it's only for internal use in GT drivers
    * HB_inkey_enum changed to int - this is bit field not enumerated type.
      Many of C/C++ compilers forbid bit operations on enum types and
      forcing it by casting which finally exceeds the enum range is defined
      as bug because it may badly interacts with some compiler optimizations

  * harbour/include/hbvm.h

  * harbour/include/hbvmpub.h
    * separated internal and external API. Now the definitions for
      internal HVM structures and functions are excluded by default
      they could be enabled if user include hbvmopt.h before other
      header files. Such operation should be done _ONLY_ by core
      code - if 3-rd party developers make sth like that then it's
      for their own risk and such code may stop to work with next
      Harbour versions. Without hbvmopt.h the internal structures
      like HB_ITEM, HB_DYNS, ... are  mapped to 'void' so there is
      no way to access their members so we can modify them in the
      future without afford for 3-rd party code.
      There is one small exception 'type' should be the first member
      for HB_ITEM structure because I used a small ugly hack in
      HB_IS_*() macros with castin PHB_ITEM to HB_TYPE* - it works
      without speed overhead but if you think that it will be
      better/cleaner to not use such tricks then it's enough to
      change HB_ITEM_TYPE() definitions in hbvmpub.h - see note.
    * cleared the usage of HB_EXPORT - to avoid problems with some C/C++
      compilers we agreed that the only one common way of using HB_EXPORT
      is adding it ad begining of declaration - please keep this convention
      in the future.
    + added new functions:
      hb_extIsObject(), hb_codeblockId(), hb_idleSleep(),
      hb_fsGetOsHandle(),
      hb_dynsymFindSymbol(), hb_dynsymGetSymbol(),
      hb_dynsymSymbol(), hb_dynsymName(),
      hb_dynsymMemvarHandle(), hb_dynsymAreaHandle(), hb_dynsymSetAreaHandle()
    * changed hb_arrayClone() declaration to:
         PHB_ITEM hb_arrayClone( PHB_ITEM pArray )
    * changed hb_arrayFromParams() declaration to:
         PHB_ITEM hb_arrayFromParams( int iLevel )
      The previous version needed a pointer to stack relocatable area
      so any stack resizing could cause GPF.

    % rewritten jump optimization
      ! fixed some minor problems
      * do not optimize jumps and local variable access by shorter
        PCODE version and HB_P_NOOP when jump optimization is
        disabled, this is a note I left in source code in few places:
         /*
          * optimizing jumps here by shorting them and setting HB_P_NOOPs
          * only slow down the compilation process for three reasons:
          * 1. When it's dummy jump to next instruction we need two passes
          *    in hb_compOptimizeJumps() to fully remove it
          * 2. hb_compOptimizeJumps() also make jump shortcutting in each pass
          * 3. When Jump Optimization is disabled (-kJ) then it cause slowness
          *    at runtime because we will have more HVM loops: first  for the
          *    shorter jump and next for the HB_P_NOOP PCODE(s)
          * [druzuz]
          */

      + added support for multi passes in jump/dead code elimination
        (hb_compOptimizeJumps())
        By default is set upto three passes.
        Now hb_compOptimizeJumps() keeps all compiler internal data clean
        on exist and can be called any times and does not change other
        compiler's functions behaviors
      + added dummy jumps elimination
      + added optimization for:
            IF .T.
            IF .F.
            WHILE .T.
            WHILE .F.
         etc.
      * restored empty BEGIN/RECOVER sequence block elimination
        if Jump Optimization is enabled then it marks the block
        with HB_P_NOOPS else it cut the generated PCODE
      + added dead code eliminator (new functions hb_compCodeTraceMarkDead()/
        hb_compPCodeTrace() - it works only when Jump Optimization is
        not disabled)
      As a result of the above we have smaller and faster PCODE.

      I do not think that we will have meta code support in the reasonable
      time and because I need some valid compiler data/structures like
      updated table of all jumps for real C code (not PCODE in .c files)
      generation then I decide to make some modifications and the above
      is in practice a side effect of this work.

      Ryszard I've removed some of your extensions which are no longer
      necessary and some other (keyboard sequence redefinition) should

      slang 2.x - It's unicode ready, tries to detect terminal mode
      (utf-8/iso) at startup and switch the internal logic to
      iso/unicode mode. When compiled with slang 1.4x or 2.x
      and terminal is in UTF-8 it can display all characters like
      in DOS if only used font have them or good fall-back table is
      loaded (f.e. the one created by QRCZAK)

      what broke GNU make compilation for some compilers
      This libraries should be included automatically when RDD lib
      is included by *.cf files

   Summary:
      The whole patch (cvs diff -uN) is ~1.5MB length and I cannot describe
      everything in details - sorry but it was too much modifications in
      one commit so now just some of general notes.
      The header files included as is does not have any information about
      internal HVM structures and some functions. In practice only HB_SYMB
      is public and it has to be public for .c files generated from .prg
      so I force the fixed size of this structure (alignment independent)
      by redefining some members to union with void * - it's a little bit
      ugly trick but it effectively eliminates the problem of linking
      binaries compiled with differ alignment C compiler switches.
      The structures like HB_ITEM, HB_CODEBLOCK, HB_STACK, HB_DYNS are not
      longer defined and pointers to the defined as void * - like in Clipper
      the ITEM structure. It caused that I had to add some new functions
      to make some operation still possible to implement. If I missed sth
      and any of you will have a problem with your code then please inform
      me about it and after a small discussion on Harbour developers list
      we can decide if other functions should be added.
      The internal API is still accessible. It's enough to include "hbvmopt.h"
      file before other header files to enable it. Now only files in
      source/vm directory include it.
      The 3-rd party code which does not include hbvmopt.h (or tries to
      set some internals macros) should be safe for future HVM modifications
      and will work also with new binaries so 3-rd party library developers
      should remember about it. If they won't then it's only their and
      their clients problem not Harbour developers.
      With this modifications I also create new GT model which is similar
      to the one used by RDD with multi inheritance. It can be quite easy
      extended to simultaneously load more then one GT subsystem (sth like
      work areas in RDD) but I left it for the future when someone may
      need it. hbapigt.h file now contains only information about public
      functions and does not have any code which depends on current
      internal implementation - it should be backword compatible as long
      as somone did not try to use internal GT functions.
      The internal GT system use hbgtcore.h file which should not be
      included by 3-rd party code as long as someone will not make new
      GT driver. The internal GT code is new so I expect that it will
      be changed yet in the nearest future (I'm waiting for other developers
      feedback) and in such case any 3-rd party GTs will have to be updated.
      How it works:
         The base GT driver (GTNUL) is fully functional GT driver which
         makes all operations on memory buffer. After each screen write
         Flush() method is called which check for dispcount() and if
         it's 0 then call Refresh() method to update modified area by
         Redraw() method. This method is dummy in GTNUL and external
         output with this GT can be reached by outstd()/outerr() which
         are now redirected to GT methods. A simple GT driver may overload
         only Refresh() method to give full screen output.
         Application can use only this GT driver and it seems to be very
         good choice for GUI and background daemon/service programs.
         This GT is loaded at startup then all other GTs can be loaded
         later and inherit from the previously loaded GT drivers.
         The new GT driver can overload as much method as wants/needs.
         Now all GT operations are implemented as GT method so GT driver
         can easy change their default behavior, f.e. it may fully overload
         color parsing methods and use differ or extended to Clipper color
         definitions.
         I rewrote all existing GTs to work with new GT model.
         OS2 users - please test GTOS2 which I was not able to test and
         see the note in Redraw() method. If possible please make some
         speed tests.
         In fact now there is much more internal operations then it was
         before but because they are done on memory only then current
         code is much faster in this GT drivers which so far makes all
         operations on real video area. I made some tests with GTNUL
         and tests/vidtest.prg and the total overhead is minimal. Now
         dipbegin()/dispend() in practice does not cost anything so it
         gives additional speed improvement in application which extensively
         use it.
         More then one GT driver can be linked with final binaries and
         chose on application startup by //GT<NAME> switch and/or environment
         variable HB_GT=<name>
         In the RTL is new GT function GTSYS() which works in similar way
         to RDDSYS() in RDD subsystem and for linking default GT driver
         for given platform. When RTL is compiled the default GT driver
         is set to HB_GT_DEFAULT envvar and if not exist to HB_GT_LIB
         envvar and if it also does not exist to hard coded platfom GTs
         (see source/rtl/gtsys.c and source/rtl/Makefile for rules)
         Adding to source code:
            ANNOUNCE GTSYS
         disable linking the default GT driver and:
            REQUEST HB_GT_<name>
         for linking given (<name>) GT driver, f.e.: REQUEST HB_GT_WIN
         If you are working in SH environment (Linux and other *nixes users,
         DJGPP bash, MinGW shell then it's possible to use -gt<name> switch
         in hblnk / hbmk scripts to force linking GT drivers (it could be
         repeated with different <name>) and the first one becomes the default
         one. F.e.:
            xhbmk -m -n -w -es2 -gtcrs -gtsln -gtstd -gtpca vidtest.prg
         Usually the GT driver are loaded at HVM startup but it's possible
         to load it later. I created new GT driver CTW which gives full
         CT3 like Window system. The CT3 extended driver change the behavior
         of some function in Clipper extended driver, f.e WRITECON() or
         SETPOS() with parameters out of screen range. So I implemented it
         CTW as RT GTs which is loaded when some of CTWIN function is used
         (f.e. WOPEN()/WBOARD()) and inherits from any existing GT driver.
         This is full CT3 WIN implementation with all detail behaviors I
         found (with some CT3 bug fixes). It does not have any CT3 limitations
         and can be used for any virtual screen/window size though I hardcoded
         CT3 limitation for backword compatibility. If somone will want to
         remove it then it will be enough to delete few lines from ctwin.c
         file. I'm not CTWIN Clipper user so maybe I missed some side effects
         in this driver and was not able to well test it so if you will find
         any incompatibilities then please inform me.
         THe default GT buffer uses 32bit character cell internally but
         in savescreen/restscreen it uses VGA compatible two bytes character
         cell. Some GT drivers may want to use differ character cell.
         Now GTCRS and GTSLN use 32bit character cell by default. They
         need additional information about character set (box/normal) to
         properly display box characters. It is possible to force in this
         GT drivers using Clipper compatible character cell by calling:
            hb_gtInfo( GTI_COMPATBUFFER, <lCompat> ) -> <lPreviousSeting>
         but in may cause that box drawing characters will be lost in
         some countries after RESTSCREEN(). It will depend on used code
         page.
         HB_GTINFO() is new function which works in similar way to DBINFO()
         in RDD. It allows to retrieve/change some of GT driver settings.
         GTI_* actions are defined in hbgtinfo.ch - it has all GTI_*
         definitions used in xHarbour. Now in Harbour only few of them
         are implemented.
         The new three .prg functions:
            HB_SETKEYCP( <cTermCP> [,<cHostCP>] )
            HB_SETDISPCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
            HB_SETTERMCP( <cTermCP> [,<cHostCP>] [,<lBoxChar>] )
         have been added. They set automatic input (HB_SETKEYCP)
         and output (HB_SETDISPCP) (or both: HB_SETTERMCP) character
         translation. They are also important for some GTs which
         informing them about used internal code page for unicode
         translation (GTXWC, GTSLN) and/or chosing proper character
         set (standard/alternate) for letters and other (f.e. box
         drawing characters) (GTCRS, GTSLN),
            <cTermCP> is encoding used on external (terminal) side
            <cHostCP> is encoding used internally, if not given then
                      current code page set HB_SETCODEPAGE() is used.
                      some of GTs which uses unicode output may
                      ignore <cTermCP>
            <lBoxChar> is optional parameter which interacts with dispbox()
                       output disabling switching to alternate character
                       set in some GTs. It effectively causes that if internal
                       (host) code page contains some letters on the box char
                       positions then they will be shown also by box drawing
                       functions like dispbox() instead of CP437 characters.
                       In some cases it could be useful. By default lBoxChar
                       is not set and GTs which can switch between standard
                       and alternate character set (GTCRS, GTSLN) will try to
                       use alternate character set for box drawing functions.

      Victor: I removed some of your functions. They can be very easy
      implemented with hb_gt_GetChar()/hb_gt_PutChar() but I do not want to
      make them part of documented external API because some GT drivers may
      want to use absolutely differ color definitions and they will stop to
      work so I do not want to make this functions documented external API.

      Ryszard: Setting alternative debug keys does not longer work.
      I like such possibilities but it should be implemented in differ
      way to f.e. using HB_GTINFO interface to allow low level GT driver
      extensions, f.e. in *nixes using CTRL+[A-Z] and SIGINT, SIGQUIT,
      SIGTSTP signals for real asynchronous setting of debug/cancel flag
      without keyboard polling from main HVM loop. I would like to discus
      about such more general solution.

* harbour/source/common/expropt2.c
    * casting

  * harbour/include/hbdate.h
    + added hb_dateJulianDOW() - retrieve day of week from Julian's date

  * harbour/source/rtl/dates.c
  * harbour/source/common/hbdate.c
    * moved hb_dateDOW(), hb_dateDecStr() and hb_dateEncStr() to
      hbdate.c - Ryszard I'd prefer to keep this function together
      It will be much easier to update them.
    + added HB_STR_DATE_BASE for conversion to string - Clipper
      compatibility though we are not 100% Clipper compatible in STOD()
      because we will have to reduce functionality (supported date
      range) to reach it. In Clipper STOD(DTOS()) is not revertible.
      I decided to make it revertible in [x]Harbour for the whole supported
      in string conversion range: 0000/01/01 : 9999/01/01
    % optimized hb_dateEncode()
    * some minor fixes for Clipper compatibility

  * harbour/source/rtl/dateshb.c
    * use faster and Clipper compatible hb_dateJulianDOW() instead of
      hb_dateDOW()

  * harbour/source/rdd/nulsys/Makefile
  - harbour/source/rdd/nulsys/nulsys.prg
  + harbour/source/rdd/nulsys/nulsys.c
    * replaced .prg code with #pragma begindump/enddump by native C code
      rtl/symbol.prg have to be updated yet.

  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
    * synced with xHarbour
