    ! 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/macro/macro.y
    + added small hack for two BCC/OW warnings
  * harbour/source/compiler/harbour.yyc
  * harbour/source/compiler/harbour.yyh
  * harbour/source/macro/macro.yyc
  * harbour/source/macro/macro.yyh
    * regenerated with modified Bison version which should give code
      without BCC warnings - I cannot promise I'll keep it in the
      future but I will try.

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

  * harbour/source/vm/classes.c
    * added support for (@func()):eval(...)

* harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
    ! fixed some possible false warning messages

  * harbour/include/hboo.ch
  * harbour/source/vm/classes.c
    + added support for HB_OO_MSG_PROPERTY and HB_OO_MSG_CLASSPROPERTY
      to make some xHarbour users happy ;-)

  * harbour/common.mak
  * harbour/harbour.spec
  * harbour/include/hbcompdf.h
  * harbour/source/compiler/Makefile
  + harbour/source/compiler/hbcmplib.c
    + added HB_COMPILE() function - it accepts exactly the same parameters
      as harbour compiler and makes the same job :-)

  * harbour/utils/hbrun/Makefile
  * harbour/utils/hbrun/hbrun.prg
    + added support for compilation and direct execution of .prg files
      Now hbrun can accept as first parameter .hrb or .prg file and if
      it's .prg file it's compiled and then executed just like .hrb one.
      In *nixes if you copy compiled hbrun to /usr/bin directory then
      you can add to your .prg files as first line:
         #!/usr/bin/hbrun
      and then after setting executable attribute you can directly
      execute them, f.e.:
         ./test.prg
      If you are using Linux then you can also chose default gt driver
      by dding to above line: //gt<name>
      F.e.
         #!/usr/bin/hbrun //gtstd

  * harbour/source/vm/itemapi.c
  * harbour/source/vm/macro.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/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)

      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

* harbour/include/hbexprop.h
  * harbour/source/common/expropt1.c
    + added hb_compExprAsNumSign()

  * harbour/include/hbexprc.c
    * optimize lValue++ and ++lValue

  * harbour/source/common/hbdate.c
    * minor optimization

  * harbour/source/compiler/cmdcheck.c
    * maximum supported warning level should be 3 not 4

  * harbour/include/hbxvm.h
  * harbour/source/compiler/gencc.c
  * harbour/source/vm/hvm.c
    * use separate functions for equal and exactly equal operations
    * cleanup and some other minor optimizations

  * harbour/source/compiler/hbopt.c
    * optimize PCODEs for code like: lVar:=lVar, sVar:=sVar, mVar:=mVar, ...
  * harbour/include/common.ch
    * changed HB_SYMBOL_UNUSED( symbol ) to ( symbol := ( symbol ) )
      It's a little bit simpler version and now it's also stripped by
      PCODE optimizer

  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
    * eliminated some redundant rules
    * optimized PCODEs generated for FOR/NEXT code and removed some old
      hardcoded optimization for local variables - if it will be worth
      to optimize then such optimization will be done by expression
      optimizer
    * chaned a little bit WITHOBJECT syntax.
      Now WITHOBJECT somefunc(); END is not silently ignored and call
      to somefunc() is left. This optimization also works when there
      are empty line between WITHOBJECT and END

  * harbour/source/rdd/dbf1.c

  * harbour/source/compiler/hbfix.c

    * divided hbfix.c into two separated functions:
      - hb_compFixFuncPCode() which only fix generated PCODE updating
        local parameters numbers when PARAMETERS is used
      - hb_compOptimizePCode() which makes PCODE optimization
      It allows to not execute hb_compFixFuncPCode() when PARAMETERS
      is not use and execute hb_compOptimizePCode() more then once in
      optimization process.

  * harbour/hbgtmk.sh

  * harbour/source/compiler/hbcomp.c
  * harbour/source/compiler/hbgenerr.c
  * harbour/source/compiler/hbident.c
    * changed code for generating in PCODE line numbers and module names
      there was serious problem with line numbers and module names in old
      code - in many cases line numbers were not generated at all or
      generated in wrong places. Also file module name was not updated
      when inside of function some code was included with #include
      For such situation now modified version of HB_P_MODULE is generated
      with module name only but without function name, f.e.:
         HB_P_MODULE    "test.prg:"
      exactly the same form of HB_P_MODULE is used in xHarbour.
      Debugger code should be updated to recognize such HB_P_MODULE version
      Ryszard any chance that you can look at it?
      And what about syncing with xHarbour debugger?
      I can add some missing functions to compiler and HVM but I do not
      want to update next peace of code myself. Sorry but I do not have
      enough time. I'd prefer to finish some other things I'm working.
      If Ryszard is busy can someone else try to port xHarbour debugger
      to Harbour?

    ! 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/rdd/workarea.c
    * formatting

  * harbour/include/hbapi.h
  * harbour/source/vm/extend.c
    + added missing hb_storptrGC()

  * harbour/include/hbapicdp.h
  * harbour/source/rtl/cdpapi.c

      code translation
    * formatting

  * harbour/source/rtl/gtsln/kbsln.c
  * harbour/source/rtl/gtxwc/gtxwc.c
    * use new unicode translation function format. It also fixes problem
      with space translation in GTLSN used in UTF8 mode

  * harbour/include/hbapiitm.h
  * harbour/source/vm/itemapi.c
    + added hb_itemCopyToRef(), hb_itemMoveToRef(), hb_itemMoveRef(),
      hb_itemUnRefWrite()

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

         local s, c
         s:="abcdefghijklmnopqrst"
         for each c in @s
            if c$"aeio"
               c:="*"

    ! fixed typo in expression type checking in IIF() reduction - it was
      working because wrongly used macros has the same values as the valid
      ones
    - 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:
         &("myfunc(<exp>, @var1, @var2)")
      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(...)()

    * 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.

    + 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

      ! 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.

    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.

    ! 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

      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.

    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.

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/rtl/gtxwc/gtxwc.c
  * harbour/source/rtl/gtxwc/gtxwc.h
    * changed the selection code - now both PRIMARY and CLIPBOARD
      selections are set by Harbour. It should work with any programs
      which uses any of them but I'd like to remove one of this selections
      or give user a way to chose the preferred one. I can also add support
      for automatic setting/clearing/pasting PRIMARY selection by GTXWC
      with mouse and shift key. I'm waiting for opinions.
    + added basic support for GFX operations

    + added new GT by Mauricio Abre based on Allegro cross platform
      graphic libraries.
      Code borrowed from xHarbour and modified by my for new Harbour
      GT API.

        However there are still leaks when the compiler aborts
        compilation due to errors.
      + added optimalization of '+=' '-=' '*=' '/=' operators
      + added hb_itemGetNDDec(),
        hb_itemPutHBLong(),
        hb_itemPutNumType()
        borrowed from xHarbour

      NOTE: new pcodes:
      HB_[PLUS|MINUS|MULT|DIV]EQ
      HB_[PLUS|MINUS|MULT|DIV]EQPOP
      recompile all sources.

      Do not use any extern ... in source code to aviod possible mistakes
    ! fixed some mistakes in BOOL/int declarations
    * use hb_fsFreeSearchPath() to free allocated path list

  * harbour/source/compiler/harbour.c
    * keep functions and public variables definitions in header files.
    + added memory statistic module - it's disabled now because too
      much errors is reported.
      Ryszard I hope it will help in locating memory leaks in compiler.
    * begun of cleaning static variables to make compiler code
      ready for reentrance.

  * harbour/source/rtl/gtstd/gtstd.c
    ! fixed cursor positioning

  * harbour/config/os2/gcc.cf
    + added socket library

* harbour/source/compiler/harbour.c
    * do not strip redundant line information when compiled for debug (-b)

  * harbour/source/compiler/harbour.y
    ! fixed typo in hb_compSequenceFinish() call - Ryszard please check me.
      using iNumber instead of lNumber caused that on big endian machines
      begin sequence / endsequence block was stripped

  * harbour/source/compiler/hbdead.c
    ! fixed stupid typo in counting length of debug variable/module names
