   * 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 ...
