* include/hbdefs.h
    + Added HB_ISALNUM() macro.
    + Added HB_ISSPACE() macro. Please review.

  * source/contrib/hbver.c
    * isspace() -> HB_ISSPACE().

  * contrib/rddads/ads1.c
    ! toupper() -> HB_TOUPPER()

  * contrib/xhb/hbxml.c
    + Readded #include <ctype.h> because this one still uses isspace().

  * harbour/include/hbmacro.ch
  * harbour/source/compiler/ppcomp.c
  * harbour/source/compiler/hbusage.c
  * harbour/source/compiler/cmdcheck.c
    + added -ko (allow operator optimizations) compiler switch
      It's disabled by default.

  * harbour/include/hbexprb.c
    * removed HB_ADD_SUB_ONE_OPT macro and enable optimizations covered
      by it when -ko switch is used.

  * harbour/source/common/expropt2.c
    * disabled <exp> + 0 => <exp>, <exp> + "" => <exp>, - - <exp> => <exp>
      optimizations for default compiler settings. They can be enabled by
      -ko compiler switch
    + added optimizations for numeric values and + operator which uses
      standard mathematical + behavior for real numbers:
         a + b + c == a + ( b + c )
         a + b == b + a
      It's disabled by default and can be enabled by -ko compiler switch.
      There are also other similar optimizations which can be added in
      this way.

    + PCode optimizations:
        1) Self := QSELF(), Self:method -> QSELF():method
        2) Declared, but unused variables are removed from code
      These optimizations are enabled if jump optimizations are enabled.

    + added recursive pcode tree tracer. It is capable to generate new
      warning: Variable %s is assigned, but not used. 
      Warning is not generated in these cases:
        1) unoptimal Self := QSELF() pcode [generated by preprocessor rules]
        2) if variable name starts with '_nowarn_'. This allows to 
           suppress warning in case unoptimal pcode is generated by 
           preprocessor rules
        3) assigned value is NIL. This let us force garbage collection
           using oVar := NIL
      Warning has warning level 3.
      ; NOTE: if you are using -w3 -es2 in makefiles, you'll need to fix your 
              redundant code to compile the project

      but only fixed half of files. There are a lot of garbage code here.
      I do not thing this code is working... 
      I used fallback method: restored original files and used -w2
    ; NOTE: hbmake.prg has about 140 unused assignments.
      I've also fallback to -w2, because some of unused code is complex, 
      ex., ASCAN() with block parameters. I'm not using hbmake, and I'm 
      affraid to break something important. 

  * compiler/hbpcode.c
    - removed Ron's copyright on hb_compStrongType(). We do not have this 
      functions in the compiler at all. I guess this text is just a result 
      of .c header copy-paste from xHarbour's hbstrong.c some time ago.

* harbour/contrib/xhb/Makefile

  * harbour/contrib/xhb/xhbfunc.c

  * harbour/common.mak
  * harbour/source/compiler/hbmain.c
  + harbour/source/compiler/compi18n.c
    * moved hb_compI18n*() functions to separate file covered by GPL with
      Harbour exception - Thank to Mindaugas

  * harbour/include/hbcompdf.h
  * harbour/include/hbexpra.c

  * harbour/include/hbexprb.c
  * harbour/source/common/expropt1.c
  * harbour/source/compiler/Makefile
  * harbour/source/compiler/ppcomp.c
    * added support for plural forms:
         hb_i18n_ngettext[_noop|_strict]( <nExp>, <cText> | <acText> ;
                                          [, <cContext> )
      <acText> is accepted only as array of literal strings even if
      _strict suffix is missing - if it's a problem then we can change it.
      hb_i18n_ngettext_noop() is reduced only when it has valid parameters
      The default plural index expression used for reduction at compile
      time is: iif( <nExp> == 1, 1, 2 )
      If second parameter of hb_i18n_ngettext_noop() is <cText> or <acText>
      length is 1 then it's reduced to <cText> or acText[1] else if second
      parameter is <acText> with more then 1 item then it's reduced to
         <acText>[ iif( <nExp> == 1, 1, 2 ) ]
      and if <nExp> is literal numeric expression is farther reduced to
      given array item. Otherwise is not reduced and warning is generated.
      The plural forms in .pot files are generated as:
         msgid ""
         msgid_plural ""
         msgid_plural2 ""
         [...]
         msgid_pluralN ""
         msgstr[0] ""
      Then real message ID is only msgid (with context if any) and
      msgid_plural* is used only for information. When the same msgid
      is used more then once in different hb_i18n_ngettext*() calls then
      plural messages are merged.
      Please remember that for strict gettext compatibility only two plural
      forms are allowed.
    * extended i18n warnings for simple types validation, f.e.:
         hb_i18n_gettext( .t. )
    * do not generate empty .pot file when source code does not contain any
      hb_i18n_*() functions
    * store in .pot files references to real source file names with paths
      respecting #include directives
    * use hb_compIdentifierNew() to hash i18n messages at compile time
    ! fixed possible bad escape encoding of i18n strings
    + added support to control -j[01] flag using #pragma directive

      Before I'll begin to work on runtime support please test these
      modifications and inform me about problems you can see with the
      above version and missing functionality.

  * harbour/include/hbsetup.h
    + added HB_CODEPAGE_DEFAULT which works like HB_LANG_DEFAULT

  * harbour/source/vm/hvm.c
    ! fixed builds which uses non EN lang or code page modules
      by forcing linking the chosen ones

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/include/hbapicdp.h
  * harbour/source/rtl/cdpapi.c
    - removed global code page variable: hb_cdp_page and moved
      code page settings to HVM stack
    + added new function hb_cdpID() which returns current code page
      character ID
    + added new functions hb_vmCDP() and hb_vmSetCDP() to get/set
      active for given thread code page structure

  * harbour/source/vm/dynsym.c
  * harbour/source/vm/itemapi.c
  * harbour/source/vm/memvars.c
    * changed memvar handles for HB_HANDLE to void * which is directly
      casted to PHB_ITEM - new memvar references
    * changed HB_DYNS declarations for MT mode. In MT mode HB_DYNS does
      not contain area and memvar handles which are moved to thread
      local HVM stack
    + added array for thread local memvar and area handles to HVM stack
    % eliminated global continues array with all memvars and detached locals
    % changed HB_IT_MEMVAR to use pointers to HB_ITEM directly - it resolve
      synchronization problems in MT mode and should also improve the speed
      and reduce memory usage. It should be well visible in applications which
      uses lot of detached locals.
    - removed hb_memvarsInit() and hb_memvarsFree() - they are not necessary
      now because we do not longer use array with all allocated memvars
      and detached local and private stack initialization is made
      automatically
    + added internal functions hb_dynsymGetMemvar()/hb_dynsymSetMemvar()
    + added hb_memvarGetValueBySym() for debugger
    * moved PRIVATE variable stack to HVM stack
    * eliminated all static variables in memvars module

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/source/rtl/fserror.c
    * moved IO errors to HVM stack
    + added special IO error handling which works without HVM stack
      It allows to use hb_fs*() functions without allocated stack
      by 3-rd party threads.

  * harbour/source/rtl/filesys.c
    * moved hb_fsCurDir() to HVM stack with special handling to work
      with HVM stack like IO errors

  * harbour/source/rdd/workarea.c
    * allocated RDD node array in bigger peaces to reduce later RT
      reallocations in MT mode. If user want to add dynamically more
      then 64 RDDs then it should synchronize this operation himself.

  * harbour/source/rdd/wacore.c
    * moved WA list, current WA, default RDD and neteer() flag to HVM stack

  * harbour/include/hbdefs.h
    - removed HB_HANDLE declaration

  * harbour/include/hbapi.h
    - removed HB_VALUE structure - it's not longer used due to different
      memvar handling
    * updated hb_struMemvar to new memvar handling
    * replaced hb_vmIsLocalRef() and hb_memvarsIsMemvarRef() with
      hb_vmIsStackRef() which respect multiple stack and new memvar
      and static structures and location in GC mark pass.

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
  * harbour/source/vm/hvm.c
    + added support for thread specific data located on HVM stack
      Now it's possible to allocate static variables which are
      local to thread. Such variables are allocated on HVM stack
      and automatically destroyed. To declare new TSD variable use:
         HB_TSD_NEW( <name>, <size>, <init>, <destruct> )
      <name> - name of variable which holds TSD handler
      <size> - size of TSD are which has to be allocated
      <init> - init function, executed when new TSD is allocated by thread
               (thread access given TSD 1-st time). This function receives
               void * pointer to allocated area.
      <destruct> - destructor function executed when HVM stack is destroyed
      f.e.:
         static HB_TSD_NEW( s_scrData, sizeof( HB_SCRDATA ),
                            NULL, hb_xSaveRestRelease );
      To initialize dynamically allocated TSD variable use:
         HB_TSD_INIT( <name>, <size>, <init>, <destruct> )
      Pointer to TSD can be accessed using hb_stackGetTSD( &<name> )
      where <name> is name of variable which holds TSD handler, f.e.:
         PHB_SCRDATA pScrData = ( PHB_SCRDATA ) hb_stackGetTSD( &s_scrData );
      See source/rtl/xsavescr.c as an example
      It's also possible to test if data has been already allocated for
      current thread by:
         hb_stackTestTSD( &<name> ) => pData
      it works like hb_stackGetTSD() but return NULL if current thread data
      has not been allocated yet.

  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
    * changed hb_stack location to thread local storage in MT mode
    + added functions and macros to access/assign new HVM stack members
    + changed garbage collection mark functions to work with multiple
      stacks, thread local static and memvar variables

  * harbour/source/rtl/xsavescr.c
    * use TSD data for screen buffer to make __XSAVESCREEN()/__XRESTSCREEN()
      thread independent

  * harbour/source/rtl/setkey.c
    * use TSD data for allocated keys to make SETKEY() thread independent

  * harbour/source/rtl/math.c
    * moved math error handler, math error block, math error mode and
      math error structure to TSD

  * harbour/source/rtl/errorapi.c
    * moved error handler, error block, error launch counter and DOS error
      value to TSD

  * harbour/source/rdd/hsx/hsx.c
    * moved HSX handles array to TSD

  * harbour/include/hbapigt.h
  * harbour/source/rtl/console.c

    + added new PCODE HB_P_THREADSTATICS
    + added support for static variables which are local to thread:
         THREAD STATIC <varname [:= <exp>], ...>
      They work like normal static variables but each thread operates
      on its own copy.
    * added protection against possible double call to hb_xfree()
      It can happen due to wrong marking expressions as used by bison
      and executing destructors after our free code when syntax error
      appear.

    + added hb_gt_BaseFree() which will release current GT pointer
      locked by hb_gt_Base() function. This function will be used
      to optional automatic GT access synchronization when threads
      share the same GT.

      TODO: CTWIN is not MT safe yet - it will be updated together
            with core GT when we add multi window interface for
            thread with own console window.

  * harbour/bin/hb-func.sh
  * harbour/config/linux/gcc.cf
    + added rt lib to Linux builds

  * harbour/bin/postinst.sh
    * create MT safe version of FM stat library: fmmt

  * harbour/bin/pack_src.sh
    + added support for ZIP packing

  * harbour/include/hbapi.h
  * harbour/include/hbvm.h
  * harbour/source/vm/hvm.c
    + added hb_vmThreadInit()/hb_vmThreadQuit() functions - they initialize
      HVM for calling thread so it can execute .prg code and call HVM
      functions. They can be used by 3-rd party code threads.
    + added hb_vmUnlock()/hb_vmLock() functions which informs that
      thread will not operate on HVM structures for some time allowing
      to execute single thread only processes like GC.
    + added hb_vmThreadQuitRequest() which sends stop request to given
       thread
    + added hb_vmWaitForThreads() which stops main thread execution waiting
      for other threads
    + added hb_vmSuspendThreads() and hb_vmResumeThreads() used be GC
      to stop all HVM threads before mark/swap scan
    + added linked list of HVM stacks
    + added hb_vmTerminateThreads() used by main HVM thread in QUIT state
    * moved EXIT procedures execution from QUIT request to HVM QUIT state
      in MT mode. It may effects some non structural code which tries to
      access private variables in EXIT functions but it's much cleaner
      and understandable for user. Please remember that we guaranties
      that ALWAYS code in BEGIN SEQUENCE is _always_ executed even after
      HVM QUIT request just like destructs. Personally I think that we
      should move EXIT procedures execution also in ST mode.
    * changed startup and cleanup code for new internal structures
    * changes startup and cleanup code for MT mode
    % removed some redundant HB_ITEM type settings
    ! eliminated non MT safe code which was using reference counters
      without protection

  * harbour/common.mak
  * harbour/source/vm/Makefile
  + harbour/include/hbthread.h
  + harbour/source/vm/thread.c
    + added C level functions to manage threads and synchronization objects
      See hbthread.h for detail description. They are based on PTHREAD API
      and PTHREAD documentation can be used as reference. I intentionally
      keep this list small for easier multiplatform porting.
      Now they have been implemented for PTHREADS (POSIX threads supported by
      many different OSes), MS-Win32/64 and OS2. The OS2 version is not tested
      at all. I do not even know if it can be compiled so please make tests.
      I used Internet resources and some part of xHarbour code as documentation
      for OS2 MT API. It should be quite easy to add other platforms if necessary.
      Harbour core code needs non recursive mutexes, conditional variables and
      TLS for one pointer. If platforms does not support conditional variables
      (f.e. MS-Win or OS2) then they can be emulated using multistate semaphores.
    + added .prg functions to manage threads and synchronization objects:
         hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
         hb_threadJoin( <pThID> [, @<xRetCode> ] ) -> <lOK>
         hb_threadDetach( <pThID> ) -> <lOK>
         hb_threadQuitRequest( <pThID> ) -> <lOK>
         hb_threadWaitForAll() -> NIL
         hb_mutexCreate() -> <pMtx>
         hb_mutexLock( <pMtx> [, <nTimeOut> ] ) -> <lLocked>
         hb_mutexUnlock( <pMtx> ) -> <lOK>
         hb_mutexNotify( <pMtx> [, <xVal>] ) -> NIL
         hb_mutexNotifyAll( <pMtx> [, <xVal>] ) -> NIL
         hb_mutexSubscribe( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
         hb_mutexSubscribeNow( <pMtx>, [ <nTimeOut> ] [, @<xSubscribed> ] ) -> <lSubscribed>
      The function list should give similar to xHarbour API but they are not exactly
      the same and except of hb_mutex*() functions which should replicate xHarbour behavior.

  + harbour/source/vm/vmmt
  + harbour/source/vm/vmmt/Makefile
    + added hbvmmt library to GNU make builds.
      Non GNU make builds should be updated.

  * harbour/contrib/gtwvg/gtwvg.h
    - removed #include <comctl32.h> - my MinGW and MinGW/CE instalations do

      covered by #if version checking.

  * harbour/source/vm/dynsym.c

    * changed to work with new memvar structures and thread local static and
      memvar variables
    * added MUEXT protection for linked block lists
    + added parameter to hb_gcCollectAll() which will force GC activation
      in MT mode by temporary suspending all executed threads.
    + added logical parameter to HB_GCALL() functions which is passed to
      hb_gcCollectAll()

  * harbour/source/vm/fm.c
    * added MUEXT protection for FM statistic module
    * added MT protection for reference counters. For platforms
      which supports atomic incrmenetation/decrementation (f.e.
      Interlocked*() functions in MS-Win) such operations are
      used. For other it's MUTEX protection. It gives MT safe
      readonly access for HVM complex variables without user
      synchronization. The MUTEX protection can cause some speed
      overhead so it's good to define MT safe version of
      HB_ATOM_INC()/HB_ATOM_DEC() in hbthread.h if given platform
      has them. Now they are defined only for Windows. For other
      platforms We can define can define them in assembler for some
      most popular CPUs in the future.

  * harbour/source/vm/classes.c
    * changed class definition array. Now it keeps pointers to class

    * In MT mode allocated at HVM startup big enough array for class

  + harbour/tests/mt/mttest06.prg
  + harbour/tests/mt/mttest07.prg
    + added some demonstration/test small MT programs written
      using Harbour language. Some of them can be also compiled
      by xHarbour but xHarbour does not pass any of my tests in
      real multi-CPU machine so do not expect they will work
      correctly.

   Harbour threads needs OS threads support. Each Harbour thread is directly
   mapped to OS thread. It's not very efficient on some older system where
   cost of thread creation and/or task switching is very expensive but it
   should not be bigger problem for modern OS-es which can support threads
   in practice nearly in user space only.
   I haven't touched Harbour function calling convention which comes from
   Clipper. It means that we do not pass pointer to VM to each functions
   like CLIP or xBase++. To resolve the problem I have to use thread local
   storage (TLS) where such pointer is kept. If platform does not support
   TLS then it can be emulated by us. Anyhow the speed of accessing TLS
   data and extracting HB_STACK poitner is critical for performance.
   Some compilers depending on used hardware and OS give native support
   for TLS (f.e. __thread keyword in GCC/BCC or __declspec( thread ) in MSVC).
   This should give optimal performance. On other Harbour uses TLS functions
   like TlsGetValue() (MS-WIN) or pthread_getspecific() (PTHREAD) are used.
   OS2 gives quite interesting TLS functionality which seems to be quite fast
   though it will be interesting to know how it is iplemented internally for
   real multi CPU machines (if it depends on CPU exception then the
   performance will be bad). We need TLS only for one pointer to HB_STACK
   structure.
   I haven't added any tricks like HB_THREAD_STUB in xHarbour to reduce
   the cost of TLS access. If it will be necessary for some platform the we
   can add it.
   Except TLS Harbour threads needs OS support for non recursive mutexes or
   critical sections and conditional variables. If platforms does not support
   conditional variables (f.e. MS-Win or OS2) then they can be emulated using
   multistate semaphores. I intentionally didn't create code which may need
   recursive mutexes. The non recursive ones are often faster and some
   platforms may not support recursive mutexes so they will have to be
   emulated by us.
   Harbour uses reference counters for complex variables. It means that even
   readonly access to complex item causes internal write operations necessary
   to increment/decrement its reference counter. To make such readonly access
   MT safe we have to make incrementation and decrementation with result
   checking atomic. By default it's done by mutex inside vm/fm.c but some
   platforms have native support for atomic inc/dec operations, f.e. 
   Interlocked*() functions in MS-Win. If they are available then such
   functions should be used to not reduce the performance by mutex call
   very often used functions. For many CPUs it should be quite easy to
   implement such atomic inc/dec functionality in assembler. F.e. for
   GCC and x86@32 it may looks like:

      static __inline__ void hb_atomic_inc32( volatile int * p )
      {
         __asm__ __volatile__(
            "lock incl %0"
            :"=m" (*p) :"m" (*p)
         );
      }

      static __inline__ int hb_atomic_dec32( volatile int * p )
      {
         unsigned char c;
         __asm__ __volatile__(
            "lock decl %0"
            "sete %1"
            :"=m" (*p), "=qm" (c) :"m" (*p) : "memory"
         );
         return c == 0;
      }

   and then it's enough to define in hbthreads.h:
      #define HB_ATOM_INC( p )    hb_atomic_inc32( ( volatile int * ) p )
      #define HB_ATOM_DEC( p )    hb_atomic_dec32( ( volatile int * ) p )

   Probably I'll make it for some most popular CPUs in the future.
   In Harbour each thread which wants to call HVM functions have to allocate
   it's own HVM stack. It's done hb_vmThreadInit(). The HVM stack is freed
   by calling hb_vmThreadQuit(). This functions can be called also by 3-rd
   party threads if they want to call HVM functions or execute .prg code.
   Calling HVM functions without allocated stack will cause GPF.
   I moved most of static variables to HVM stack to make them thread
   local. But some of them like FS errors have their own alternative
   copy which is used when thread does not allocate HVM stack. It allows
   to use hb_fs*() functions without HVM stack but programmer have to
   know that error codes return by hb_fs*Error() functions can be
   overwritten by other threads which also didn't allocated HVM stack.
   To execute garbage collector scan and mark pass it's necessary to
   stop other HVM threads. Otherwise the scan may give false results.
   It's also possible to not stop threads but protect with mutex all
   operations on GC items but it will probably cause performance reduction
   and will force some other modifications. Maybe I'll implement it
   in the future.
   I didn't use any OS level thread KILL or CANCEL calls. All HVM threads
   have to be cleanly removed without any resource leaks.
   QUIT command terminate only calling thread. If main (startup) HVM
   thread call QUIT then it sends QUIT request to all existing threads.
   In QUIT state ALWAYS statements and destructors are executed.
   New thread is created by:
      hb_threadStart( <@sStart()> | <bStart> [, <params,...> ] ) -> <pThID>
   The returned value is a pointer to internal thread structure which
   can be used in JOIN or DETACH operations. Each thread should be Joined
   or DETACHED to avoid resource leaks. If programmer does not store
   <pThID> or all instances of <pThID> are destroyed then thread is
   automatically detached. I do not know clear method of thread detaching
   in OS2. If some OS2 users knows it then plase update vm/hbthread.c.
   When thread terminates then all locked by this thread mutexes are
   released.
   Each thread uses its own memvars (PRIVATEs and PUBLICs) and work areas.
   When new thread is created then it inherits from parent thread:
      - code page
      - language
      - SETs
      - default RDD
   error block is initialized to default value by calling ERRORSYS()
   and PUBLIC variable GetList := {} is created.
   The following objects are initialized to default value:
         - error block
         - math error handler and math error block
         - macro compiler features setting (hb_setMacro())
           or move them to SETs.
   We can think about inheriting them. It's also possible to add
   inheriting of all visible memvars but I do not know it's good
   idea.

   Compilation and linking:
   For MT mode HVM library should be compiled with HB_MT_VM macro.
   GNU make automatically creates hbvmmt library which should be
   linked with Harbour MT programs instead of hbvm.
   Non GNU make files should be updated.
   If given compiler support TLS then you can try to set HB_USE_TLS
   to force using native compiler TLS support. Now it's enabled by
   default only for BCC. For Linux and GCC builds it may depend also
   on used GLIBC version. In older system there is no TLS support
   at all or TLS works only for shared binaries so I haven't enabled
   it. If you will test some other compiler then please add default
   native TLS support for them in hbthread.h
   Users using hb* scripts can simply use -mt switch when they want
   to create MT program, f.e.:
      hbmk -n -w3 -es2 -mt mttest01.prg

   There are still some minor things which should be done but I'll
   do them later. Current state seems to be fully functional.
   The most important and still missing is our own file lock server
   for RDD synchronization in POSIX systems. Kernel internally
   recognize POSIX locks by PID and file i-node - not PID and file
   handle. It means that the same file open more then once by one
   process shares locks. Because POSIX locks can be overwritten
   then we do not have any synchronization between aliased workareas
   or threads using the same table in *nixes. We have to make
   synchronization ourselves. I'll create such lock server ASAP.

   Please test and enjoy using Harbour threads.

    ! fixed name conflict in privates/publics declaration.
      Harbour allows to declare memvars with the same name as file
      wide statics or fields but this extensions was not working well
      in some cases and can cause unexpected results in variable
      declaration, f.e. try this code:
               static v:="static"
               proc main()
                  public v:="public"
                  ? v, M->v
               return
      compiled with -n -w switches and also with -n -w -a before
      this fix.
    ! fixed some compile time warnings in memvars declaration to be
      more Clipper compatible
    ! fixed compiling external modules (DO <procname> [WITH <params,...>])
      when function <procname> is already declared but with different
      letter case. Harbour does not convert <procname> in DO statement
      to upper case to play well with case sensitive file systems and
      it could cause confusing warning message:
         Cannot open <procname>.prg, assumed external

      It's a "DOt Prompt" Console for the Harbour Language
         Syntax:  hbdot [<hrbfile[.prg]> [<parameters,...>]]
      It should look and work in similar way to pp/xBaseScript
      by Ron Pinkas but unlike xBaseScript is does not have preprocessor
      or simulated runtime environment but simply uses Harbour pp and
      compiler libraries to preprocess and compile commands. It means
      that it supports all language constructions also statements, f.e.:
         "for i:=1 to 10; ? i; next"
      Additionally it can also compile and execute .prg files given as
      first parameter just like hbrun.
      Please test it. If it will work as expected then we can remove
      'pp' (contrib/dot) from standard packages

    + added support for extended multiline codeblocks:
         { |<params,...>| <EOL>
            <statement1>
            ...
            <statementN>
            return <val>
         }
      Such codeblocks allow nested definitions. They can also have their
      own variable declarations (local, static, field, memvar, parameters,
      private, public) and visibility of declared variables is similar to
      nested function in Pascal but please note that there is one limitation
      which exists also for normal codeblocks (Clipper compatible behavior):
      internal codeblock local parameters and local variables cannot be
      used in nested codeblocks, f.e. such code:
            eval( { |p| eval( {|| qout( p + 1 ) } ) } )
      is illegal in Clipper and Harbour. This limitation also can be
      eliminated but but it will be necessary to make deeper modifications
      in code for local detaching changing the method of generating
      codeblocks local variables in nested blocks so unlike the above
      also some modifications in HVM will be necessary.
      Please test.

    * changed code used for variable scoping - now it's much more
      simple (only one function) and allows to use declarations in
      nested functions/codeblocks with visibility similar to Pascal
    ! fixed parsing FILED <fields,...> IN <alias>
      we were accepting code like:
         FIELD f1, f2 IN db1, f3 IN db2 IN db3
      and for all fields the last alias (db2 in this example) was used
    ! fixed calculating number of static variables with -b (debugger)
      compilation (number of file wide statics were doubled)
    ! fixed generation of static variable names for debugger when declared
      with array dimensions, f.e.:
         static sVar[3]

      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

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

  * harbour/source/vm/classes.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")

         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)

      I updated non GNU make files but I cannot tested the modifications
      - please check and fix me if necessary

    * 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/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?

  * harbour/source/vm/hvm.c
  * harbour/source/vm/itemapi.c
    ! 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.

    * updated <string> + <string> optimization and other macrotext usage

    ! 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(...)()

    * 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>
      results.

    ! generate error when PARAMETERS is used as file wide declaration.
    ! generate errors when different executable statements are used before
      first procedure - now such code was simply ignored without any errors.
    ! generate valid error messages when some declarations are used in
      wrong places
    ! fixed setting begin of executable statement flag in different .prg
      constructions.

      ! 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

    ! 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

    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

    * 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

    * 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.

    * restored support for old hb_inLine() syntax
    + added support for hb_inLine() to new PP. It can be enabled by
      -kI compiler switch. It's disabled by default.
      The new hb_inLine{} syntax is:
         [ <exp> ] hb_inLine [ ( [<params,...>] ) ] { [ <c_code> ] } [ <exp> ]
      <c_code> can contain new line characters.
      Nested hb_inLine{} in <params,...> is not supported. If you think
      it's important I can add it in few lines.
      This version does not break any valid Clipper syntax, hb_inLine is
      not reserved word and hb_inLine can be repeated many times in the
      same line. F.e. this code can be properly preprocessed and compied if
      you disable in compiler old hb_inLine() syntax and enable the new one
      by -kcI Harbour compiler switch:

         proc main()
         local hb_inLine := " (var) "
         ? hb_inLine{ hb_retc("inLine"); } + hb_inLine(" parameter ") {
              hb_retc( hb_parc( 1 ) );
              } + "!" + hb_inLine + hb_inLine() { hb_retc( ":-)" ); } + ;
           hb_inLine() + "{}"
         return
         function hb_inLine()
         return " func() "

      So from user point of view this version have real "inline" syntax.
      To be clear: I'm not a fun of any C inline extensions. They works
      only when we use .c code as compiler backend so the code which uses
      them cannot be used in .hrb files and any other format we will add
      in the future which do not support later C code compilation. F.e it
      will not work in compiler integrated with HVM or with .NET
      Anyhow if someone finds it useful then I think that it should be
      properly implemented. This is the reason I added the new version.
      The old one I left only for backward compatibility. It breaks any
      code which uses hb_inLine keyword can be used only once in a line
      and it does not have "inline" so IMHO it should not be enabled by
      default.
      I would like to hear your opinion about default compiler switches:
         1. should we disable both: hb_inLine() and hb_inLine {}
         2. should we disable hb_inLine() and enable hb_inLine {}
         3. should we disable hb_inLine {} and enable hb_inLine()
         4. should we enable both: hb_inLine() and hb_inLine {}

  + harbour/tests/hbinline.prg
    + added test code for new hb_inLine{} syntax

    + 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.

   * source/vm/hvm.c

      * fixed compilation of code that uses '@' pass by
       reference. The following syntax is no longer supported:
       var := IIF( .T., @var, var )
       however you can still use the following:
       funcall( IIF( bPassbyRef, @someVar, someVar ) )
      +added support for the following statement:
         WITH OBJECT <objexpression>
            ...
         END
       inside this statement you can use simplified form of sending
       messages to the object specified by <objexpression>
         :message( )    instead objexpression:message()
         :property      instead objexpression:property
       The runtime error will be generated at the time of message
       sending (or property access/assign) if <objexpression>
       is not a value of type object.
       You can use the reserved property:
         :__withobject
       to access/assign the controlling object.
      *fixed support for command line response file (@file.clp)
       to be compatible with Clipper (Clipper genertes a single
       obj file)
      *fixed memory leaks when there is a fatal error in autoopened
       module (using DO ... statement)
      *implicit startup functions are removed from the list of
       functions before generation of output code

   * source/pp/ppcomp.c
   * source/pp/pplib.c
   * source/pp/ppcore.c
      * redefinition of #define no longer causes a memory leak
      * fixed repeatable optional clauses
         #xcommand SET <var1> [, <varN>] WITH <val> =>
          <var1>:=<val>[; <varN>:=<val>]
      * fixed compilation of optional clauses (when used in different
        order then declared) -this fixes the following long
        waiting bug:
         #command MYCOMMAND [<mylist,...>] [MYCLAUSE <myval>] => ;
            MyFunction( {<mylist>} [, <myval>] )
         MYCOMMAND MYCLAUSE 321 "HELLO"
      * fixed restricted macro match marker <x:&>

   * tests/Makefile
   - tests/pretest.prg
   + utils/hbpptest
   + utils/hbpptest/Makefile
   + utils/hbpptest/pretest.prg
      * moved file 'pretest.prg' from tests to separate directory
        to make easier validation of the preprocessor

   * TODO
      * added note to fix hb_objGetMethod() so it will not generate
        error if there is no method

   * doc/en/clipper.txt
      * added documentation for WITH OBJECT usage

* harbour/include/hbcomp.h
    + added extern hb_comp_szFile

  * harbour/include/hbinit.h
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx() respecting
      Mindaugas suggestion.
    + added HB_INIT_SYMBOLS_EX_END() macro
    * translate HB_INIT_SYMBOLS_END() macro to HB_INIT_SYMBOLS_EX_END()

  * harbour/include/hbsetup.h
    + added HB_PCODE_VER_MIN and HB_PCODE_VER both now are set to 0x0001

  * harbour/include/hbtypes.h
    * changed VM_PROCESS_SYMBOLS_EXT to VM_PROCESS_SYMBOLS_EX

  * harbour/include/hbvm.h
    + added hb_vmFindModuleSymbolName() - it returns the file name of given
      symbol if it was registered in HVM

  * harbour/source/compiler/genc.c
    * set HB_FS_LOCAL for local module functions
    * use HB_INIT_SYMBOLS_EX_END instead of HB_INIT_SYMBOLS_END

  * harbour/source/compiler/harbour.c
    * minor modifications

  * harbour/contrib/rdd_ads/ads1.c
  * harbour/source/rdd/dbf1.c
  * harbour/source/rdd/delim1.c
  * harbour/source/rdd/sdf1.c
  * harbour/source/rdd/dbfdbt/dbfdbt1.c
  * harbour/source/rdd/dbffpt/dbffpt1.c
  * harbour/source/rdd/dbfcdx/dbfcdx1.c
    * added HB_FS_LOCAL to function symbols in registered symbol tables

  * harbour/source/rdd/dbfntx/dbfntx1.c
    * added HB_FS_LOCAL to function symbols in registered symbol tables
    ! added missing break
    + added DBOI_KEYCOUNTRAW, DBOI_KEYNORAW. They works like DBOI_KEYCOUNT
      and DBOI_KEYNO in pure DBFNTX. Only with some upper level RDDs like
      RMDBFNTX which supports bit map filters they can return differ results.

  * harbour/source/rdd/workarea.c
    * changed ORDERINFO to DBORDERINFO in error message

  * harbour/source/rtl/set.c
    * respect previous settings in logical SETs if given value is not valid
      new one.
    + added misinf initialization for _SET_FORCEOPT and _SET_HARDCOMMIT.
    * changed default value of _SET_OPTIMIZE to TRUE

  * harbour/source/vm/dynsym.c
    * give the highest priority for LOCAL function symbols

  * harbour/source/vm/hvm.c
    + added hb_vmFindModuleSymbolName() - it returns the file name of given
      symbol if it was registered in HVM
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx() and added
      PCOE version checking

  * harbour/source/vm/maindllp.c
    * changed hb_vmProcessSymbolsExt() to hb_vmProcessSymbolsEx()
    * changed VM_PROCESS_SYMBOLS_EXT to VM_PROCESS_SYMBOLS_EX

  * harbour/source/vm/proc.c
    * changed to use stack macros/functions instead of direct accessing
      HB_STACK members
    + implemented PROCFILE() - it returns now real source file name
      with body of given function symbol or function executed at given
      stack level. If the source file cannot be detected then empty
      string is returned. Unlike in xHarbour it works also for static
      functions. synatx:
         PROCFILE( [ <FuncSym> | <nStackLevel> ] )
      F.e.:
         PROCFILE() -> current module name
         PROCFILE(@DBFCDX())  -> ../../dbfcdx1.c
