Przemyslaw Czerpak eeb38e90e7 2007-04-16 01:50 UTC+0200 Przemyslaw Czerpak (druzus/at/priv.onet.pl) 
* harbour/source/debug/debugger.prg
    * removed some not longer necessary GTWVW extensions

  * harbour/source/rtl/hbgtcore.c
  * harbour/contrib/libct/ctwin.c
    + added support for GTI_{NEW,GET,SET}WIN in CTWIN
      Now debugger can be used with CTWIN without any problems
