      tolower() -> HB_TOLOWER()
      toupper() -> HB_TOUPPER()

  * source/rtl/natmsg.c
    ! Fixed to use CP sensitive case conversion in
      __NATISNEGATIVE() and __NATISAFFIRM().

  * source/rtl/is.c
    ! Fixed typo in recently added hb_charIsUpper()/hb_charIsLower()
      functions.

  ; TODO: Remove DJGPP to*() hack.
  ; TODO: Replace HB_PP_UPPER(), HB_PP_ISDIGIT() with equivalent
          new macros.
  ; TOFIX: Some of the above macros should better be replaced
           by CP sensitive versions. F.e. the one in hbtip.
  ; TOFIX: Remove remaining #include <ctype.h> lines.

  * 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.

    + Added HB_OSISWINCE()
      [TOMERGE 1.0]

  * include/hbver.ch
  * source/rtl/version.c
    + Added:
      hb_version( HB_VERSION_MT )          -> <logical>
      hb_version( HB_VERSION_UNIX_COMPAT ) -> <logical>
      hb_version( HB_VERSION_PLATFORM )    -> <string> (same as ending of __PLATFORM__* macros)
      This makes these functions/macros deprecated:
      - HB_MTVM()
      - __PLATFORM__* (not for all possible situations)
    ; TOFIX: Cleanup REVISION/SVN term usage in source.

    ! change the expressions precedence - references to variables were
      wrongly marked as simple expressions

  * harbour/include/hbexpra.c
    ! fixed protection against wrong static initializers. Now code like:
         static s_var := { { func(), M->var } }
      or:

         static s_var := { @M->var }
      or:
         static s_var := QSelf()
      is not accepted by compiler and error is generated at compile
      time instead of crashing at HVM startup when static variables
      are initialized

  - harbour/source/rtl/set.c
  + harbour/source/vm/set.c
  * harbour/include/hbstack.h
  * harbour/source/vm/estack.c
    * moved from RTL to HVM
    * eliminated hb_set global structure
    * moved set structure to HVM stack
    + added internal function hb_setClone() which is used to create
      copy of SET structure for child threads
    * hidden HB_SET_STRUCT declaration - 3-rd part code must not access it
      directly. Dedicated hb_set*() functions should be used instead.
    + added new function:
         BOOL hb_setSetItem( HB_set_enum set_specifier, PHB_ITEM pItem )
      which allow to change some set by 3-rd party code.
      TODO: not all SETs can be changed yet - if someone have a while
            then please add code for missing ones.

  * harbour/include/set.ch
  * harbour/include/hbset.h
    + added _SET_CODEPAGE which works like _SET_LANGUAGE giving common
      interface

  * harbour/include/hbsetup.h

  * harbour/source/vm/hvm.c
    ! fixed builds which uses non EN lang or code page modules

  * 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/include/hbstack.h

  * 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/idle.c
    * use TSD data for idle task settings and codeblocks
    - removed hb_idleShutDown() - it's not longer necessary

  * 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/rtl/inkey.c
    * moved inkey "before" and "after" blocks to TSD

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

  * harbour/include/hbapigt.h
  * harbour/source/rtl/console.c
    - removed hb_setkeyInit() and hb_setkeyExit() - they are not longer
      necessary, allocated resources will be freed by TSD destructor
      function

  * harbour/include/hbapi.h
  * harbour/source/rtl/console.c
    * removed hb_conXSaveRestRelease() - it's not longer necessary,
      allocated resources will be freed by TSD destructor function

  * harbour/source/vm/macro.c
    * moved s_macroFlags to TSD

  * harbour/source/rtl/accept.c
    * moved accept buffer to TSD

  * harbour/source/compiler/harbour.yyh
  * harbour/source/vm/hvm.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.

  * harbour/source/rtl/menuto.prg
  * harbour/source/rtl/getlist.prg

  * harbour/source/rtl/text.prg
    * use THREAD STATIC variables to make above code MT safe

  * harbour/include/hbgtcore.h
  * harbour/source/rtl/hbgtcore.c
    + 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.

  * harbour/source/rtl/gtapi.c
  * harbour/source/rtl/inkeyapi.c
  * harbour/source/rtl/mouseapi.c
  * harbour/contrib/hbct/ctwin.c
    * free GT pointer by hb_gt_BaseFree()
      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.

  * harbour/source/vm/fm.c

    * 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

  + 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.

       These will return the screen dimensions regardless 
       of the size of an active window (when using CT 
       windows for example). Functionality is the same 
       as MaxRow(.T.) and MaxCol(.T.) previously.
     ! MaxRow()/MaxCol() extended parameters removed.
     + Added MaxRow(.T.)/MaxCol(.T.) conversions for 
       xhb lib (hbcompat.ch) in both directions.
     ; XBase++ doesn't have any extended parameters 
       for Max*() function. Flagship has two of them, 
       both of them doing something different. CAVO doesn't 
       have these functions at all.

    ! removed:
         MESSAGE <msgName> IS <mthName>
      used as synonym of:
         MESSAGE <msgName> METHOD <mthName>
      If someone was using the removed version then please update the
      code to MESSAGE ... METHOD ...
      The removed command has special meaning in Class(y) and it allow
      to define alternate names for existing messages. I'll add support
      for them in the future.

  * harbour/contrib/hbct/ctwin.c
    * added disabled code which is a workaround for some possible
      bad side effect caused by online shadow showing by CTWIN.

  * harbour/source/rtl/errorint.c
    ! fixed displaying internal error message

  * harbour/source/common/hbver.c
    * added "Rev." prefix to shown revision number

  * harbour/include/hbexprop.h

  * harbour/source/common/expropt1.c
  * harbour/source/common/expropt2.c
    + added hb_compExprReduceNegate()
    ! fixed wrong negate optimizations for platforms where HB_LONG_MAX
      is smaller then -HB_LONG_MIN, f.e. all x86 based CPUs.
    ! fixed setting the size in optimized negative numbers
    ! fixed some math optimizations to not use casting to double value
      when it's not necessary - when double precision is smaller then HB_LONG
      (f.e. on x86 it's 53 bits and HB_LONG has 64bit) such casting can damage
      up to 11 less significant bits in big 64 bit numbers.

  * harbour/source/rtl/hbinet.c
    * replaced MAKEWORD() macro with HB_MKWORD() to pacify BCC58 warnings

  * harbour/include/hbdefs.h
    + added #include <limits.h>
      It should hide some warnings related to redefined integer size constants
      Viktor if it will not help for BCC58 warnings then you will have to add
         #include <stdint.h>
      few lines below but please remember that older BCC version does not
      have it so check for the exact compiler version.
    ! changed macros which setting default numeric item size for more strict
      Clipper compatible mode. I'm not a fun of some Clipper behavior in
      calculating number size and I left some notes about it in hbdefs.h
      Anyhow this and some other modifications below should cover the
      differences you've found recently. Some things are not addressed by
      me intentionally, f.e. _itemPutNL() in Clipper always set size to 10
      without checking the maximum size so it's too small for values less
      then -999999999. Harbour compiler makes more compile time optimizations
      then Clipper. The formatting rules used by compiler are a little bit
      different then by VM so this can be source of some other differences
      to Clipper. I can easy create some examples. Harbour supports 64bit
      signed integers and Clipper doesn't. This is yet another situation
      when we may have different results then Clipper. Most of them can
      be hidden if we add new PCODE(s) for integer number with explicit
      size but I do not think it's such important to increase PCODE list.
      In few cases it will be necessary to disable some optimizations at
      all and I do not like it. In the future when I will be adding some
      new optimizations I also add compiler switch to disable/enable
      optimizations which can have such side effects for people who need
      strict formatting.

    ! fixed Harbour support for accessing string characters with array

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

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

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

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

      little bit deeper modification

  * harbour/source/compiler/complex.c

      in code like:

         retu:=myCaseClass():new()

         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/include/hbcompdf.h
     + added comment

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

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

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

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

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

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

  * harbour/source/compiler/hbfix.c
     * better optimization of PCODE generated for logical expressions

  * harbour/source/compiler/hbfunchk.c
     % use binary search instead of linear scan

  * harbour/source/rtl/minmax.c
     ! fixed GPF when MIN() or MAX() function is called with less then
       two parameters

  * harbour/source/vm/itemapi.c
     * minor optimization and formatting

* harbour/include/hbexprb.c
    * 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.

  * harbour/include/hbcomp.h
  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
  * harbour/source/compiler/harbour.yyh
    + added hb_compStatmentStart()
    ! restrict MEMVAR and FIELD usage - now they have to be located before
      executable statements like in Clipper.
    ! 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.

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

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

    ! do not use bison destructors for expressions. Internal bison logic
      cannot properly detect if expression was used or not in some of our

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

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

  * harbour/source/common/expropt1.c
  * harbour/source/common/expropt2.c
    * changed HB_MACRO_SUPPORT to HB_COMMON_SUPPORT to automatically detect
      possible conflicts between compiler and macro compiler
    ! removed first detected conflict which existed for long time
    + added hb_compExprMacroAsAlias() function to convert HB_ET_VARIABLE
      expression to HB_ET_ALIAS.

  * harbour/source/macro/macro.y
    ! fixed using prefix&macro-> and &macro.sufix-> when macro cannot be
      substituted by compiler, f.e.:
         M->v := NIL
         x := "&v.1->fld"
         M->v := "v"
         M->v1:= "data"
         ? &x
    ! fixed memory leak in macro substituted expression compilation

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

    * 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.

  * harbour/include/hbexprb.c
  * harbour/include/hbexprop.h
  * harbour/source/common/expropt2.c
    + added compile time optimization for STOD(cConstDateString)
      covered by -kh compiler extension (default)
      It allows to keep the same source code for Clipper and
      Harbour and benefits from data constants without using
      0dYYYYMMDD values

  * harbour/source/vm/classes.c
    * restored the original 3-rd parameter in  hb_clsAdd to void(void) -
      PHB_FUNC - and added translation for PHB_SYMB to not force using
      [P]HB_SYMB in 3-rd party code

  * harbour/source/vm/estack.c
    * added protection against possible GPF after executing
      hb_stackBaseProcOffset() when first item on the stack
      was not HB_IT_SYMBOL - it can happen in some seldom
      cases. Probably some more general solution like leaving
      first dummy item on HVM stack for breaking stack scan
      loops will be better. I'll think about it.

  * harbour/source/vm/itemapi.c

    * casting

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

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

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

  * harbour/source/rdd/nulsys/Makefile
  - harbour/source/rdd/nulsys/nulsys.prg

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

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

            [EXIT]
         [OTHERWISE]
            ...
         END

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

   Notice:
      The above changes apply only to FLEX version!

  * harbour/source/vm/hvm.c

      BTW - is this really necessary? I copy it form hb_itemUnRef()
      but in fact it cannot detect all possible item reference cycles
      if they appear - can they appear?

   * Sorry but it's too much modification for full description
     cvs diff gives file 785982 bytes length. So I only count the
     main things:
   ! cleand the code (no more warning messages under Linux and GCC and
     DOS OpenWatcom) - some of them were real bugs
   ! cleaned all endian dependend code I've found - now Harbour can be
     compiled on LITLE and BIG endian machines - for some other like
     PDP ENDIAN it's enough to define proper macros in hbdefs.h
   + added macros for to get/put values in chosen byte order:
         HB_GET_LE_[U]INT{16,24,32,64}( pPtr )
         HB_GET_BE_[U]INT{16,24,32,64}( pPtr )
         HB_PUT_LE_[U]INT{16,24,32,64}( pPtr, nVal )
         HB_PUT_BE_[U]INT{16,24,32,64}( pPtr, nVal )
   + added macro HB_CAST_BYTE_NUMBERS_OFF which disables casting in
     HB_{GET|PUT}_{LE|BE}_* macros - it's necessary for some platforms
     like ALPHA DEC.
   ! cleaned the code for 64bit machines
   * changed all parameters in hb_date* functions (day, month, year, week)
     from LONG to int - it doesn't change binary compatibility for 32bit
     machines but can cause troubles with compiling the old source
   + changed HB_IT_LONG type to HB_LONG which is mapped to long long
     by default for 32 bit machines.
   + change HB_IT_INTEGER to be real 'int' C type not 'short int'
   + added HB_IS_NUMINT() macro
   + added hb_parnll, hb_stornll, hb_retnll, hbretnlllen, hb_itemPutNLL,
     hb_itemPutNLLLen, hb_itemGetNLL which operates on LONGLONG
   + added hb_parnint, hb_stornint, hb_retnint, hb_retnintlen,
     hb_itemPutNInt, hb_itemPutNIntLen, hb_itemGetNInt which operates on
     HB_LONG
   + added HB_PUSHLONGLONG pcode
   + changed compiler and optimizer to use HB_LONG numbers and reduce
     conversion from to double which may damage the 64bit number.
   + common functions for string to number conversions for compiler, RTL
     and RDD to reduce problems with differ FL values for the same number:
     hb_compStrToNum(), hb_valStrnToNum(), hb_strToNum(), hb_strnToNum()
   + common function hb_numRoun() which uses exactly the same algorithms
     as string to number conversion for the same reason - please keep
     this functions together.
   + hack inside hb_numRound() similar to the one used by CL5.3
   + hb_numInt() which uses uses the same hack as hb_numRound()
   + rewritten number to string conversion
   + some new string manipulation functions hb_strncpy(), hb_strncat(), ...
     They works differ the the C one - always set 0 at the end, the buffer
     has to be n+1 bytes length, the n is total size of buffer not the
     left free space.
   ! cleaned some code which operates on ASCIIZ string to avoid potential
     buffer overflow
   + updated RDD code - it's the first part - in few days I plan to change
     workarea structure in both projects - it will break any 3rd party RDDs
     so they have to be updated. I want to add SUPERTABLE into workarea
     to allow creating new RDD on-line.
   ! cleaned the bugs with negating integers - on most machines (like x86)
     the integers are not 0 symmetric - it means that x = -x does not work
     for {INT,LONG,LONGLONG}_MIN (hb_vmNegate, ABS())
   + cleaned error messages to be Clipper compatible.
   + updated build process for .DEB packages - now hb* scripts and shared
     libs are created by standard make install
   * added new .prg #defines: __PLATFORM__<cPlatfrom>,
     __ARCH{16|32|64}BIT__, __LITTLE_ENDIAN__|__BIG_ENDIAN__|__PDP_ENDIAN__
