Viktor Szakats e5abaa5fb4 2010-02-09 02:12 UTC+0100 Viktor Szakats (harbour.01 syenar.hu) 
* src/vm/runner.c
  * src/vm/garbage.c
  * src/vm/classes.c
  * src/rtl/cdpapi.c
  * src/rtl/cdpapihb.c
  * src/rdd/dbcmd.c
  * include/hbapicdp.h
  * include/hbapiitm.h
  * include/hbextern.ch
  * include/hbdefs.h
  * include/hbsetup.h
  * include/hbapi.h
    - Deleted code guarded with (previously disabled) HB_LEGACY_LEVEL2

  * include/rdd.api
  * include/clipdefs.h
    + Permanently enabled HB_LEGACY_LEVEL2 related changes.

  * contrib/xhb/bkgtsks.c
    - Deleted HB_OS_WIN_USED. It wasn't used.

  * include/hbapi.h
  * src/vm/cmdarg.c
    * hb_winmainArgGet() changed to not use Windows types.
      This function is declared in hbapi.h and this header
      shouldn't depend on windows.h.

  * include/hbwince.h
  * include/hbsetup.h
    * HB_OS_HAS_DRIVE_LETTER is now configured in central
      place (hbsetup.h) for WinCE platform also.

  * include/hbwince.h
  * include/hbdefs.h
    * Windows (CE and not-CE) specific declarations moved from
      hbwince.h to hbdefs.h.

  * include/hbdefs.h
    % hbwince.h inclusion now better guarded to not include it
      for non WinCE platforms.
    + HB_OS_WIN_USED macro will now autodetected by checking
      whether windows.h was included before this header.
      This is required for hbwince.h. I don't like it, since
      hbapi.h still depends on windows.h for WinCE platform, 
      which still ties us to unnecessary windows.h inclusion 
      rules. Rather, hbwince.h should be included directly
      by .c files when needed and when HB_OS_WIN_CE is defined.
      After all this our little Windows API implementation 
      for compilers which need it.

  * include/hbdefs.h
  * include/hbwmain.c
    + hb_winmainArgInit() declaration moved to hbwmain.c, the
      only place where this is used.
    * Deleted HB_EXPORT from hb_winmainArgInit. Pls speak up if
      this is wrong. It's possible to move this back to hbdefs.h,
      but parameter types should be changed to ANSI ones.

  * contrib/gtwvg/gtwvg.c
  * contrib/gtwvg/gtwvg.h
  * contrib/gtwvg/wvggui.c
  * contrib/gtwvg/wvgcuig.c
  * contrib/gtwvg/wvggui.h
  * contrib/gtwvg/wvgwin.c
  * contrib/gtwvg/wvgutils.c
  * contrib/gtwvg/wvgcore.c
  * contrib/gtwvg/wvgwing.c
    - Deleted HB_OS_WIN_USED. Now it should work without it.
      windows.h was already included in non-official method, so
      it's now okay also.
