      action hb_xvmPushAParams

  * harbour/include/hbexprb.c
  * harbour/src/common/expropt1.c
  * harbour/src/vm/hvm.c
    + added support for special PRG function:
         HB_ARRAYTOPARAMS( <aValue> ) -> <aValue>[ 1 ] [, <aValue>[ N ] ]
      It can be used in the same context as multivalue macros
      or ... operator and converts array to list of parameters, i.e.:
         proc main
            local aValue, aIndexes

            aValue := { 1, { 2, 3, "abcde" } }

* harbour/bin/hb-func.sh
    ! restored default optimization flag (-O3) in hb* scripts

  * harbour/harbour.spec
    ! fixed recent modification

  * harbour/contrib/rddads/ads1.c
  * harbour/contrib/rddads/adsfunc.c

    ! fixed wrongly used C reference operator

  * harbour/contrib/hbwin/win_prn2.c
  * harbour/contrib/hbwin/wapi_commctrl.c
  * harbour/source/vm/maindllp.c
    ! fixes for unicode builds

  * harbour/include/std.ch
    + added SET TIME FORMAT [TO] <f>

  * harbour/include/set.ch
  * harbour/include/hbset.h
  * harbour/source/vm/set.c
    + added _SET_TIMEFORMAT
      The folowing modifiers are supported:
         hh - hours
         mm - minutes
         ss - seconds
         fff - fraction part of seconds
         p - 1-st letter from PM / AM signature. When used time is shown
             in 12 hour format otherwise 24 hour format is used
      ex: Set( __SET_TIMEFORMAT, "hh:mm pm" )
      default _SET_TIMEFORMAT value is "hh:mm:ss:fff"
    + added C function: char * hb_setGetTimeFormat( void );

  * harbour/include/hbpp.h
  * harbour/source/pp/ppcore.c
    + added support for timestamp constant values in the form:
         t"YYYY-MM-DD HH:MM:SS.fff"
      The exact accepted timestamp pattern is is:
         YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      i.e.:
         tValue := t"2009-03-21 5:31:45.437 PM"
      or:
         YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
      with literal "T" as date and time part delimiters (XML timestamp
      format), i.e.:
         tValue := t"2009-03-21T17:31:45.437"
      The folowing characters can be used as date delimiters: "-", "/", "."
      if PM or AM is used HH is in range < 1 : 12 > otherwise
      in range < 0 : 23 >

  * harbour/source/compiler/complex.c
  * harbour/source/compiler/harbour.y
  * harbour/source/compiler/harbour.yyc
  * harbour/source/compiler/harbour.yyh
    + added support for t"YYYY-MM-DD HH:MM:SS.fff" time stamp constant
      to compiler
    + added support for VFP datetime constant values:
         { ^ [ YYYY-MM-DD [,] ] [ HH[:MM[:SS][.FFF]] [AM|PM] ] }
      The following characters can be used as date delimiters: "-", "/".
      Dot "." as date delimiter is not supported.
      There is no limit on number of characters in YYYY, MM, DD, HH, MM,
      SS, FFF parts. Important is only their value. This is the format
      in semi PP notation:
         { ^ <YEAR> <sep:/-> <MONTH> <sep:/-> <DAY> [[<sep2:,>]
           [ <HOUR> [ : <MIN> [ : <SEC> [ . <FRAQ> ] ] ] [AM|PP] ] }
      In practice it allows to also parse xHarbour datetime constant
      values with compatible conditions though xHarbour support onlu "/"
      as date delimiter.
      NOTE: there is one important difference to VFP and xHarbour in
      decoding above format. In VFP and xHarbour when date part is
      missing then it's set by default to: 1899-12-30 so this code:
         { ^ 12:00 }
      gived the same results as:
         { ^ 1899/12/30 12:00 }
      Harbour does not set any default date value when timestamp
      constant value contains only time part.
      If you want we can change it for strict VFP compatiblity.
      Now this extension is enabled by default for testing. In the future
      it will be probably covered by HB_COMPAT_FOXPRO macro.

      RT conditions.
    + added HB_IS_TIMESTAMP() and ISTIMESTAMP() macros
    + added HB_IS_DATETIME() and ISDATETIME() macros - they return true
      if item/parameter is DATE or TIMESTAMP type.

      and xhb_vmPushTimeStamp()
    + added support for timestamp values in relational operators:
         <, <=, >, >=, =, ==
      When two timestamp values are compared then VM compares date and
      time parts in both values.
      When date and timestamp values are used in <, <=, >, >=, = operations
      then VM compares only date part in both values.
      When date and timestamp values are used in == operation then VM
      compares date part in both values and then check if time part
      of timestamp value is 0.
    + added support for timestamp values in + and - math operations.
      The following rules are used in timestamp arithmetic:
         <t> + <t> => <t>
         <t> - <t> => <n>
         <t> + <n> => <t>
         <n> + <t> => <t>
         <t> - <n> => <t>
         <d> + <t> => <t>
         <t> + <d> => <t>
         <d> - <t> => <n>
         <t> - <d> => <n>
      When number is result or argument of timestamp operation then the
      its integer part is a number of day and fractional part is the time.

  * harbour/source/rtl/dateshb.c
    + added new .prg functions to mange date and timestamp values:
      HB_DATETIME() -> <tTimeStamp>
      HB_CTOD( <cDate> [, <cDateFormat> ] ) -> <dDate>
      HB_DTOC( <dDate> [, <cDateFormat> ] ) -> <cDate>

      HB_CTOT( <cTimeStamp>, [ <cDateFormat> ] [, <cTimeFormat> ] ) ->
                                                            <tTimeStamp>
      HB_TTOS( <tTimeStamp> ) -> <cYYYYMMDDHHMMSSFFF>
      HB_STOT( <cDateTime> ) -> <tTimeStamp>
         <cDateTime> should be in one of the above form:
            - "YYYYMMDDHHMMSSFFF"
            - "YYYYMMDDHHMMSSFF"
            - "YYYYMMDDHHMMSSF"
            - "YYYYMMDDHHMMSS"
            - "YYYYMMDDHHMM"
            - "YYYYMMDDHH"
            - "YYYYMMDD"
            - "HHMMSSFFF"
            - "HHMMSSF"
            - "HHMMSS"
            - "HHMM"
            - "HH"
         Important is number of digits.
      HB_TSTOSTR( <tTimeStamp> ) -> <cTimeStamp> // YYYY-MM-DD HH:MM:SS.fff
      HB_STRTOTS( <cTimeStamp> ) -> <tTimeStamp>
         <cTimeStamp> should be in one of the above form:
            YYYY-MM-DD [H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
            YYYY-MM-DDT[H[H][:M[M][:S[S][.f[f[f[f]]]]]]] [PM|AM]
         The folowing characters can be used as date delimiters: "-", "/", "."
         T - is literal "T" - it's for XML timestamp format
         if PM or AM is used HH is in range < 1 : 12 > otherwise
         in range < 0 : 23 >
      HB_HOUR( <tTimeStamp> ) -> <nHour>
      HB_MINUTE( <tTimeStamp> ) -> <nMinute>
      HB_SEC( <tTimeStamp> ) -> <nSeconds>   // with milliseconds

    + added support for timestamp values to MIN() and MAX() functions.
      when only one of given parameters is timestamp value and other
      is date value and date parts are equal then always date item
      is returned as both MIN() or MAX() value.

  * harbour/source/rtl/dates.c
    + added new C functions: hb_timeFormat(), hb_timeUnformat(),
      hb_timeStampFormat(), hb_timeStampUnformat()

  * harbour/source/rtl/valtype.c
    + added .prg functions: HB_ISDATETIME(), HB_ISTIMESTAMP()

  * harbour/source/rtl/transfrm.c
    + added support for timestamp items formatting.
    + added new function modifier @T.
      When @T is used without @D then only time part of timestamp value
      is formatted and return.
      When @D is used without @T then only date part of timestamp value
      is formatted and return.

  * harbour/source/rtl/tbrowse.prg
    + display timestamp values

  * harbour/source/rtl/philes.c
    + accept timestamp value as second parameter of HB_FSETDATETIME()
      function
    + store file data and time in second parameter of HB_FGETDATETIME()
      as timestamp value.
    Old parameters (2-dDate, 3-cTime) are still supported but please think
    about removing them - they are redundant.

  * harbour/source/rtl/filesys.c

  * harbour/source/rdd/dbffpt/dbffpt1.c
    + added support for indexing timestamp fields
    + added support for using DATE values with timestamp fields
      which replicate HVM behavior.
      SEEK and SEEKLAST with date value when active index is on
      timestamp positions to 1-st or last record where date part
      of indexed timesamp value is equal.
      Settings scopes to date values when active index is on timestamp
      value reduce the visible record range to these ones which have
      date part of timestamp value in the range of dates values used
      for scopes. It possible to mix date and timestamp values in scope
      and set one scope to date value and the second to timesamp.

  * harbour/source/rdd/sdf1.c

  * harbour/contrib/hbmzip/hbmzip.c
    + updated HB_ZipFileCreate( hZip, cZipName, tDateTime, cTime, ... )
      functions to optionaly accept timestamp value in 3-rd parameter
      instead od dDate, and cTime in 3-rd and 4-th parameters.
    + updated HB_UnzipFileInfo( hUnzip, @cZipName, @tDateTime, @cTime, ... )
      to return timestamp value in 3-rd parameter instead of date value.
      TODO: Please think about removing 4-th parameter from:

   The following contrib files should be updated but I'm leaving it to
   other developers who want to keep this code alive:
         contrib/hbtip/utils.c
         contrib/hbvpdf/hbvpdf.prg
         contrib/hbvpdf/hbvpdft.prg
         contrib/hbwin/win_dll.c
            some minor cleanups if necessary and authors will find
            timestamp values usable

         contrib/hbole/ole2.c
         contrib/hbwin/win_ole.c
            add support for timestamp values in OLE

         contrib/rddado/adordd.prg
         contrib/rddads/ads1.c
         contrib/rddads/adsx.c
         contrib/rddsql/...
            add support for timestamp values in RDDs

   Warning: this implementation is not xHarbour compatible. There are many
   important differences. Mostly on C level and used API. Please be careful
   in porting xHarbour source code to Harbour.

  - 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

  * 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

    + added new function hb_cdpID() which returns current code page
      character ID
    + added new functions hb_vmCDP() and hb_vmSetCDP() to get/set

  * 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/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

    * 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.

    + 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.

         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")

         /*** 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

                       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

  * harbour/include/hbpp.h

    ! added protection against automatic word concatenation in some cases
    ! fixed preprocessing expressions when match marker matches ';' token

  * harbour/source/rtl/Makefile
  + harbour/source/rtl/itemseri.c
    + added functions for item serialization: HB_SERIALIZE() and
      HB_DESERIALIZE() - these function are not binary compatible
      with xHarbour functions with the same names but make very
      similar job with the exception to serialization of codeblock
      and object variables - Harbour does not allow to serialize
      codeblocks and serialize objects as arrays.
      In most cases these functions can replace the xHarbour ones
    + added HB_DESERIALBEGIN() and HB_DESERIALIZE() functions covered
      by HB_COMPAT_XHB macro - this functions are only for compatibility
      with existing xHarbour code, In Harbour HB_DESERIALBEGIN() is
      dummy function which returns first parameter and HB_DESERIALNEXT()
      is a simple wrapper to HB_DESERIALIZE() so it's not necessary to
      use them.

  * harbour/source/rtl/hbinet.c
    * changed INET*() functions to HB_INET*() and enable them for default
      build
    + added INET*() functions wrappers covered by HB_COMPAT_XHB macro

  * harbour/source/rtl/hbrandom.c
    + added HB_RANDOMINT() - xHarbour compatible

  * harbour/source/rtl/len.c
    + added support for HASHes

  * harbour/source/rtl/valtype.c
    + added support for HASHes
    + added set of HB_IS*() functions - they are a little bit faster then
      calling VALTYPE( v ) == <cVal>
    - removed HB_ISBYREF() - this function cannot longer work, it was using
      a Clipper incompatible anomalies in passing variables by reference I
      fixed so it has to stop to work. If it will be realy necessary to
      implement HB_ISBYREF() function then please inform me - it will have
      to be done at compiler level or with some much deeper HVM stack
      checking.

  * harbour/source/vm/extend.c
    ! fixed hb_extIsArray() and hb_extIsObject() to work well with
      parameters passed by reference.
      Please note that now hb_extIsArray() return TRUE only for pure arrays
      not object values.

  * harbour/contrib/Makefile

    + 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)

    ! 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.

      + 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

   * source/vm/hvm.c
   * source/vm/macro.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

          <var1>:=<val>[; <varN>:=<val>]
      * fixed compilation of optional clauses (when used in different
        order then declared) -this fixes the following long

  * harbour/source/compiler/hbdead.c
    + added support for dead code elimination in functions which uses
      SWITCH ...; CASE ...; ...; END syntax

  * harbour/source/compiler/harbour.c
  * harbour/source/compiler/hbfix.c
    ! fixed optimization for HB_P_PUSHLOCALNEAR and HB_P_POPLOCALNEAR.
      It was a long existing bug not reported so far because 0, 1 and 2
      PCODEs uses only one BYTE and bad PCODE tracing in hbfix.c didn't
      caused bad side effects as long as number of locals in function
      was smaller then 768. Now for functions HB_P_PUSHLOCAL and
      HB_P_POPLOCAL is used and later changed to NEAR version in hbfix.c
      if possible.

  * harbour/source/compiler/hbfix.c
    * join sequential jumps to optimize constructions like:
         while ...
            ...
            if ...
               exit
            endif
         enddo

  * harbour/source/compiler/hbdead.c
    * remove HB_P_END PCODE also at the and of function if is repeated
      just before, f.e. in code like (source/rtl/color53.prg):
         Function RADGRDEFCO( cColor )
            if isdefcolor()
               Return applydefau( cColor, "W/N", "W/N", "W+/N")
            Else
               Return applydefau( cColor, 3, 1, 4)
            endif
         Return nil
      Now such redundant constructions like above are fully stripped by
      compiler anyhow if someone has time and think is important then can
      clean also this .prg code.

  * harbour/source/compiler/hbpcode.c
  * harbour/source/vm/hvm.c
    + added support for generating real C code not PCODE in .c files.
      Now with  -gc3 Harbour will generate .c files with real .c code
      which is later compiled to real machine code.
      I left PCODE only for code block definitions though it's also
      possible to have even code block compiled to machine code but
      we will have to add a flag to codeblock structure which will
      be checked at runtime and proper method of execution in EVAL
      will be chosen. If you think it's worth of afford then I can
      add it too in some spare time.
      The final binaries are noticable longer then the one which has
      only PCODE but they are faster. The speed improvement depends
      on type of operations. The pure Clipper code which does not
      execute any external time consuming C functions compiled with
      -gc3 is from 10% to 50% faster.
      The side effect of generating pure machine code is also harder
      recompilation but it does not mean that is impossible. If sth
      can be executed by some machines (virtual or hardware) then it
      can always be decompiled by definition.
      This modification opens door for farther optimization, f.e. when
      we will have fully working strong type support then we can add
      using native .c types.
      In fact this module is PCODE to .c translater not part of compiler
      and can be used as separate module to translate generated PCODE,
      f.e. .hrb files.
      Maybe in the future we will change the compiler to generate meta
      code not directly PCODE and it will be possible to make optimizations
      on this meta code which will depend on selected output type:
      VHM PCODE, C code, .NET code, etc. but at this moment adding support
      for .c compilation directly into compiler will make the compiler code
      too much complicated for me - IMHO it's better to invest time into
      clear separation to FRONT_END->REAL_COMPILER->BACK_END
      Please make test with your code. I rebuild whole Harbour code with
      -gc3 set in HB_FLAGS in harbour/config/rules.cf and all seems to
      work correctly. hbtest returns exactly the same results.
      I also made tests with my programs and they work correctly but
      I had to define actions for all PCODEs and it's possible that made
      some typos in some of them which are very seldom used so your tests
      will be very important.

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

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

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

      hb_dynsymSymbol(), hb_dynsymName(),

    * changed hb_arrayClone() declaration to:

    * changed hb_arrayFromParams() declaration to:
         PHB_ITEM hb_arrayFromParams( int iLevel )
      The previous version needed a pointer to stack relocatable area
      so any stack resizing could cause GPF.

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

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

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

      Please not that at runtime it looks for a file
      /etc/harbour/hb-charmap.def where user can fully tune output
      for his terminal. This file is included with proper path in
      binaries created by make_rpm.sh and make_tgz.sh
      Ryszard I've removed some of your extensions which are no longer
      necessary and some other (keyboard sequence redefinition) should
      be done in a little bit differ way. I would like to talk about it
      when you test current code.
      Added support for extended mouse keys (middle button and wheel).

  * harbour/source/rtl/gtdos/Makefile
  * harbour/source/rtl/gtdos/gtdos.c
  - harbour/source/rtl/gtdos/mousedos.c
    * rewritten for new GT API
      Fixed some small problems, finished mouse code which for DJGPP
      is fully Clipper compatible with real mouse SAVE/RESTORE code.
      For other compilers it should be updated depending on memory
      model and used DPMI driver (if any).

  * harbour/source/rtl/gtos2/Makefile
  * harbour/source/rtl/gtos2/gtos2.c
  - harbour/source/rtl/gtos2/mouseos2.c
    * rewritten for new GT API
      Fixed some problems and finished the mouse code.
      Please test it - I made all modifications without OS2 and
      I was not able to make any test. I'm interesting in information
      if it works and the speed difference - f.e. results from
      tests/vidtest.prg run with previous and current version.

      and finished so now it's full functional GT driver
      I'm interesting in keyboard sequences used by PC-ANSI drivers
      in DOS so it will be possible to implement also support for
      extended keys input.

      added support for slang 1.4x patched for UNICODE (Debian
      patches used by most of current Linux distributions) and
      slang 2.x - It's unicode ready, tries to detect terminal mode
      (utf-8/iso) at startup and switch the internal logic to
      iso/unicode mode. When compiled with slang 1.4x or 2.x
      and terminal is in UTF-8 it can display all characters like
      in DOS if only used font have them or good fall-back table is
      loaded (f.e. the one created by QRCZAK)
      Added support for extended mouse keys (middle button and wheel).

      GT some of my programs and they work quite well ;-) of course
      without colors.

      code form xHarbour - this GT can work in XWindow environment only
      and create its own window for  console output. It delays the
      initialization to the moment when user try to display anything on
      the screen so even without X Window system programs which uses this
      GT can work as long as use only outstd/outerr output.

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

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

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

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

             :__enumvalue - the value of variable
            -see tests/foreach.prg for examples

      + added warnings in cases of duplicated loop variables
       eg. FOR i:=1 TO 5
            FOR i:=i TO i+5

      -removed strong typing in the compiler (xHarbour too)
      (reactivate it by compiling with -DHB_COMP_STRONG_TYPES)

NOTE:
   The new pcodes were added - rebuild everything

   * 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 ...

     + Added support for HB_P_JAMPSHORT, HB_P_JAMPSHORTFALSE and HB_P_JAMPSHORTTRUE

   * source/compiler/cmdcheck.c
     + Added support for new switch -J[0|1] default is J1 which enables the Jump Optimizer - Use -J0 to disable.

   * source/compiler/hbgenerr.c
     - Removed following errors:
        "Jump offset too long for HB_P_JUMP needed HB_P_JUMPFAR",
        "Jump offset too long for HB_P_JUMPTRUE needed HB_P_JUMPFARTRUE",
        "Jump offset too long for HB_P_JUMPFALSE needed HB_P_JUMPFARFALSE",

     * Changed "HB_P_JUMPx not found when fixing offset" to "Jump PCode not found"

   * source/include/hberrors.h
     - Removed following defines:
   	#define HB_COMP_ERR_INVALID_JUMPTRUE            46
   	#define HB_COMP_ERR_INVALID_JUMPFALSE           47
   	#define HB_COMP_ERR_JUMP_NOT_FOUND              48

   * source/include/hberrors.h
     + Added following to __FUNC
   	ULONG  * pNOOPs;                 /* pointer to the NOOP array */
   	ULONG  * pJumps;                 /* pointer to the Jumps array */
   	int    iNOOPs;                   /* NOOPs Counter */
   	int    iJumps;                   /* Jumps Counter */

   * source/include/hbpcode.h
     + Added HB_P_JAMPSHORT, HB_P_JAMPSHORTFALSE and HB_P_JAMPSHORTTRUE

* source/include/hbpcode.h
     + Added HB_P_JUMPFAR, HB_P_JUMPFARFALSE, and HB_P_JUMPFARTRUE

   * source/compiler/hvm.c
     + Added support for HB_P_JUMPFAR, HB_P_JUMPFARFALSE, and HB_P_JUMPFARTRUE to support longer than 2^15 jumps.

   * source/compiler/harbour.c
     * Enhanced hb_compGenJump(), hb_compGenJumpFalse(), hb_compGenJumpTrue(), hb_compGenJumpHere() and hb_compGenJumpThere()
       to utilize HB_P_JUMPFAR, HB_P_JUMPFARFALSE, and HB_P_JUMPFARTRUE to support longer than 2^15 jumps.

   * source/compiler/genc.c
     + Added support for HB_P_JUMPFAR, HB_P_JUMPFARFALSE, and HB_P_JUMPFARTRUE to support longer than 2^15 jumps.
