  - 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/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/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/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.
      Non GNU make builds should be updated.

  * harbour/contrib/hbnf/fttext.c
    ! fixed casting

  * harbour/contrib/gtwvg/gtwvg.h
    - removed #include <comctl32.h> - my MinGW and MinGW/CE instalations do
      not have them. If it exists in some newer ones then it has to be
      covered by #if version checking.

  * harbour/source/vm/dynsym.c
    - removed hb_dynsymLog() and hb_dynsymMemvarHandle()
    * modified code to be MT safe and improved speed of some operations
    * added MUEXT protection for global dynamic table access

  * harbour/include/hbapi.h
  * harbour/source/vm/garbage.c
    * changed to work with MT HVM
    * 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
      structures.
    * In MT mode allocated at HVM startup big enough array for class
      definitions to avoid later RT reallocations. It effectively eliminates
      MUTEX synchronization for class structure access.
    * protect by MUTEX code for new class creation

  * harbour/source/debug/dbgentry.c
    * eliminated hbvmopt.h and direct accessing to HVM structures

  * harbour/source/rtl/gtclip.c
    * protect with MUTEX access to internal clipboard data

  * harbour/source/rdd/nulsys/nulsys.c
    + added hb_rddCloseAll()

  + 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.

  * harbour/contrib/hbct/ctwin.c

      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.

      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.

   * 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__
     !!! cPlatfrom can have lower letters (for xHarbour compatibility)
     If you do not like it please change it.
   * others ...
