* harbour/include/hbgtinfo.ch
    + added GTI_ADDKEYMAP and GTI_DELKEYMAP

  * harbour/include/hbapicdp.h
  * harbour/source/rtl/cdpapi.c
    + added const to declarations of some function parameters

  * harbour/include/hbgtcore.h
  * harbour/source/rtl/Makefile
  + harbour/source/rtl/gtchrmap.c
  * harbour/source/rtl/gtcrs/Makefile
  - harbour/source/rtl/gtcrs/chrmap.c
  * harbour/source/rtl/gtcrs/gtcrs.c
  * harbour/source/rtl/gtcrs/gtcrs.h
    * hb_gt_chrmapinit() common function now for different GT drivers
    * minor cleanup in GTCRS code

  * harbour/include/hbcompat.ch
    + added some new translation rules

  * harbour/include/hbapi.h
    * cleanup comment

  * harbour/source/pp/ppcore.c
    ! fixed line numbering when errors are reported in different order
      due to preprocessing extended code block

  + harbour/source/rtl/gttrm
  + harbour/source/rtl/gttrm/Makefile
  + harbour/source/rtl/gttrm/gttrm.c
    + added new GT driver - it's terminal driver like GTCRS and GTSLN
      but it does not use any external library like [N]CURSES or SLANG
      so it can be compiled in nearly all POSIX systems. It's not such
      flexible like curses or slang base drivers because instead of
      using termcap/terminfo databases to extract terminal capabilities
      it uses some hard coded sequences for few terminals (now Linux, ANSI,
      XTERM) but it should cover users requests in 95% of cases. Terminals
      I tested are quite well supported (GTTRM works even better then GTCRS
      or GTSLN and is much faster in full screen mode - 2-4 times).
      I noticed that most terminal emulators works much better with GTTRM
      then with GTCRS or GTSLN due to limited list of used escape sequences
      so some minor differences in each terminal implementation are not
      noticeable. GTTRM automatically detects ISO/UTF8 terminal mode and
      chose valid output what should also help *nix users.
      Now I would like to ask BSD and MacOSX users to test GTTRM in these
      systems with pure text console and XWindow terminal emulators. I'm
      interesting in any problems you may found.

  * harbour/source/vm/hvm.c
    + added protection for possible GPF caused by wrong .prg code

  * harbour/source/vm/maindllp.c
    % store function addreses in static variables to improved execution
      speed
    + added support for compilers which does not use "_" as function prefix
    + added support for using with harbour*.dll

  * harbour/source/vm/memvars.c
    + added new method of detaching enumerators and array item references
      covered by HB_COMPAT_XHB macro. xHarbour does not work in such way
      but the final results are similar.

  * harbour/source/vm/dynlibhb.c
    + added protection against passing wrong pointer items to HB_LIB*()
      functions

  * harbour/source/common/reserved.c
    * cleaned warning

  * harbour/bin/hb-func.sh
  * harbour/config/hpux/global.cf
  * harbour/config/darwin/global.cf
  * harbour/config/linux/global.cf
  * harbour/config/sunos/global.cf
  * harbour/config/bsd/global.cf
    + added GTTRM to library list
