  * include/Makefile
  + include/hbzlib.h
  * include/hbzlib.ch
  * src/rtl/Makefile
  * src/rtl/hbzlib.c
    + added new C functions weakly bound with ZLIB library:
         HB_SIZE hb_zlibCompressBound( HB_SIZE nLen );
         HB_SIZE hb_zlibUncompressedSize( const char * pSrc, HB_SIZE nLen,
                                          int * piResult );
         int hb_zlibCompress( char * pDst, HB_SIZE * pnDst,
                              const char * pSrc, HB_SIZE nLen, int iLevel );
         int hb_zlibUncompress( char * pDst, HB_SIZE * pnDst,
                                const char * pSrc, HB_SIZE nLen );
      these functions can be used by any C code without forcing ZLIB liking.
      If user usese in his code HB_ZCOMPRESS() function or has
         REQUEST HB_ZCOMPRESS
      then above funcitons are automatically bound with linked ZLIB library.
      Otherwise they return 0 or HB_ZLIB_RES_UNSUPPORTED error.

  * src/rdd/dbf1.c
    * small code simplification
    ; added note about alternative numeric value rounding when
      pure binary integer fields (without decimal places) are
      assigned.

  * src/common/hbdate.c
    ! added missing header for WinCE builds

  * include/hbexpra.c
    * minor simplification

  * src/vm/macro.c
    + added new implementation for MemVarBlock() function. It's much faster
      and does not force dynamic symbol table scanning on each call

  * src/rtl/Makefile
  - src/rtl/memvarbl.prg
    - removed previous implementation of MemVarBlock()

  * src/rtl/tgetint.prg
    ! fixed __Get() and __GetA() to return NIL when cVarName parameter
      is not string (CA-Cl*pper compatible)
    ! fixed __GetA() to return NIL when given aIndex parameter or value
      returned by variable block is not array (CA-Cl*pper compatible)
    ! fixed __Get() and __GetA() to use FieldWBlock() instead of manually
      created macro block which didn't respect workarea
      (CA-Cl*pper compatible)
    ! fixed __GetA() to create SET/GET block instead of access block
      (CA-Cl*pper compatible)
    ! fixed  __Get() and __GetA() to not create simple SET/GET macro
      blocks but always force memvar usage (CA-Cl*pper compatible).
      Please remember that
         &( "DATA" )
      gives code which tries to access field then memvar but
         &( "DATA := .T." )
      gives code which always tries to assign memvar and does not even
      check if "DATA" field exists in current WA. It means that macro
      compiled code like:
         &( "{|_1| iif( _1 == NIL, DATA, DATA := _1 ) }" )
      should not be used because gives higher priority for fields in
      access operation and always assigns memvars, if necessary creating
      them.
    ! allow to dynamically create memvars for get objects in error handler
      (CA-Cl*pper compatible)
    % use much faster MemVarBlock() instead of manually created codeblock
      which activates dynamic symbol table scanning on each call
