* src/vm/runner.c
    ! Minor to prev.

  * include/hbapi.h
  * src/vm/extend.c
    + Added hb_parnsize(), hb_retnsize(), hb_stornsize() functions.
    ; NOTE: These should be used in place of hb_parnl(), hb_retnl(),
            hb_stornl() when passing HB_SIZE types.
    ; TODO: Use them all accross Harbour if they are correct and
            after being finalized.

  * src/vm/itemapi.c
    + Added hb_itemGetNSize(), hb_itemPutNSize() functions.
    * DATETIME stuff in hb_itemGetNL() marked as HB_LEGACY_LEVEL3.
    ; QUESTION: It's marked as to be deleted in the TODO, so maybe we should
                rather delete it.

  * include/hbapiitm.h
  * src/rtl/filesys.c
    + hb_fsReadAt(), hb_fsWriteAt(): Added support for Win64 HB_SIZE.
    ; QUESTION: I assume these functions have the purpose of being
                atomic seek + read without moving the file pointer,
                which means current modification isn't safe. How
                can this be solved given Windows doesn't seem to have
                64-bit read/write API calls?
    ! Fixed old copy-paste typos in Windows OVERLAPPED initialization,
      where the lines were ended with command instead of semicolon,
      they didn't cause any harm though in their former location.
    % Reverted a minor change from prev commit to make it
      possibly a little bit faster, like it was before.

  * src/rtl/hbzlib.c
    + Added casts (at external interface calls) and other fixes to
      make it build for Win64 without warnings.

  * src/rdd/dbfntx/dbfntx1.c
  * src/rdd/dbfnsx/dbfnsx1.c
  * src/rdd/dbfcdx/dbfcdx1.c
  * src/rdd/dbffpt/dbffpt1.c
  * contrib/rddbmcdx/bmdbfcdx.c
    * HB_ULONG -> HB_SIZE where appropriate to avoid Win64 errors
      and some warnings. I'm still not comfortable to touch this
      code, but it could certainly need a type cleanup.

  * include/hbdefs.h
    + Added HB_PFS macro which holds the printf() format string
      for HB_SIZE value.
    ; TODO: Use it all accross Harbour.

  * contrib/sddmy/sddmy.c

  * contrib/hbssl/pem.c
  * contrib/hbssl/rand.c
  * contrib/hbssl/evp.c
    + Added necessary casts at external component boundaries to
      make Win64 builds warning-free.

  * contrib/hbct/ctstrfil.c
    + HB_ISIZ -> HB_FOFFSET, hb_fsSeek() usage, other type cleanup
      to handle file offsets correctly.

  * contrib/xhb/hbnxs.h
  * contrib/xhb/hbcrypt.c
    ! Fixed warnings for Win64.

  * contrib/hbwin/win_prn3.c
  * contrib/xhb/dbf2txt.c
  * contrib/xhb/fparse.c
    * int -> HB_ISIZ for Win64.

  * contrib/xhb/freadlin.c
    * hb_fsSeek() -> hb_fsSeekLarge().

  * contrib/sddfb/sddfb.c
    * Minor type cleanup to make Win64 warning-free.

  * contrib/hbsqlit3/hbsqlit3.c
    + Added necessary casts at external interface calls.
    % Deleted one dummy operation from SQLITE3_FILE_TO_BUFF().

  * contrib/rddsql/sqlmix.c
  * contrib/rddads/adsx.c
    * HB_ULONG -> HB_SIZE.

  * contrib/gtwvg/wvgutils.c
  * contrib/gtwvg/wvgcore.c
    ! int -> HB_ISIZ/HB_SIZE
    + Added necessary casts at external component boundaries to
      make Win64 warning-free.

  * contrib/rddads/ads1.c
    * HB_ULONG -> HB_SIZE

  * contrib/hbtip/utils.c
    * int -> HB_ISIZ
    ! Fixed to use HB_FOFFSET type to save/restore file position.

  * ChangeLog
    + Added missing item to previous log entry:
      ! Fixed hb_fsCurDirBuff() for Win64.

  ; It's quite large commit, nevertheless I'd highly appreciate
    peer review, and certainly there will be places which need
    better or different solution for Win64.

 BMDBFCDX RDD:
 ----------------------------------------------------------------------------

 Is a DBFCDX RDD compatible with clipper 5.3, use SET OPTIMIZE ON to make a
 static bitmap filters, with SET OPTIMIZE OFF works as harbour DBFCDX.

 Addons:

     BM_DbSeekWild( uKey, [lSoftSeek], [lFindLast], [lNext], [lAll] ) => .T./.F. or aSeekRec when lAll clause
     BM_Turbo( lOnOff ) // Is only recomendable to use it on creating FILTERS
     BM_DbGetFilterArray() => aFilterRec
     BM_DbSetFilterArray( aFilterRec )
     BM_DbSetFilterArrayAdd( aFilterRec )
     BM_DbSetFilterArrayDel( aFilterRec )

 Respecting command:

 SET OPTIMIZE
 Change the setting that determines whether to optimize using the open orders
 when processing a filtered database file
------------------------------------------------------------------------------
 Syntax

     SET OPTIMIZE ON | OFF | (<lToggle>)

 Arguments

     ON enables optimization.

     OFF disables optimization.

     <lToggle> is a logical expression that must be enclosed in
     parentheses.  A value of true (.T.) is the same as ON, and a value of
     false (.F.) is the same as OFF.

     Note:  The initial default of this setting depends on the RDD.

 Description

     For RDDs that support optimization, such as DBFCDX, SET OPTIMIZE
     determines whether to optimize filters based on the orders open in the
     current work area.  If this flag is ON, the RDD will optimize the search
     for records that meet the filter condition to the fullest extent
     possible, minimizing the need to read the actual data from the database
     file.

     If this flag is OFF, the RDD will not optimize.

 Examples

     ¦  The following example enables optimization for the Inventor
        database file using the SET OPTIMIZE command:

        USE Inventor NEW VIA "DBFCDX"
        SET OPTIMIZE ON
