* contrib/hbqt/tests/wvtqt.hbp
  * contrib/hbxbp/tests/wvtqt.hbp
    ! Added missing SVN header.
    % Cleanup.

  * INSTALL
  * contrib/hbpost.hbm
  * config/global.mk
    * Changed HB_BUILD_IMPLIB to HB_INSTALL_IMPLIB to reflect
      new meaning after recent changes. With new build system
      the implibs are always created in lib working dir, and
      this setting only controls whether to copy it to final
      install directory. The default is still 'no'. Setting it
      to yes is only recommended if the installation will be
      used in local environment (3rd party .dlls) only. IOW
      never set this to yes when creating a build for other
      users (f.e. for distribution).
      INCOMPATIBLE if you used this setting, pls change it now.

  * INSTALL
    + Documented HB_STATIC_* options.

  * contrib/make.hbs
    * Updated TODO list.

  * src/debug/debugger.prg
  * src/rtl/dirscan.prg
  * tests/wcecon.prg
  * contrib/xhb/traceprg.prg
  * contrib/hbqt/tests/wvtqt.hbp

  * examples/httpsrv/session.prg
    * HB_OSPATHSEPARATOR() -> HB_PS()
    % Delete temp vars along the way.

  * utils/hbmk2/hbmk2.prg
    + Generalized internals for support for older Harbour and
      xhb versions.
    + Added -hb20 option. (thanks for asking for it so nicely ;)
