3696. Fix some SVR4.0 build problems (#3642, Satoshi Kimura).
3695. Add XErrorDB entries for the DPS extension (#3639, Juliusz Chroboczek).
3694. Fix a bigfont extension build problem on Linux/libc5 (#3637,
      Takaaki Nomura).
3693. Extend the Mouse "ZAxisMapping" option so that it can accept
      (optionally) four arguments.  The additional two are for mice that
      have two wheels or whose scroll device has two axes) (#3636, 3641,
      Kazutaka Yokota).
3692. Add support for some new mice (Microsoft IntelliMouse Explorer,
      Genius NetScroll Mouse Optical, IBM ScrollPoint) and serial PnP
      IDs (A4 Tech 4D/4D+, MouseSystems SmartScroll, Logitech Cordless
      MouseMan Wheel, 8D Scroll mouse) to the mouse driver, and update
      the mouse documentation (#3636, 3640, 3641, Kazutaka Yokota).
add some Compaq inet keyboard symbols
