A revised Mac OS 9 support patch is attached.  It also contains the
following enhancements for Carbon Emacs on Mac OS X.

  * Rearrangement of startup routine
    - The Carbon build no longer crashes with window system specific
      functions such as `xw-display-color-p' when invoked with `-nw'
      option.
    - Many window system command-line options are now interpreted.
  * WM size hints emulation
    - If the geometry is not specified explicitly, the initial frame
      is positioned at the center of screen.  A new frame is placed
      near the selected frame (10.2 and later).
    - The frame (border) that is displayed during window resize now
      changes its size according to the character boundary.
  * `select' emulation with CFSocket (not enabled by default)
    - It reduces CPU usage when Emacs is idle even with asynchronous
      processes.  Previously, polling with a short interval has been
      used for simultaneously monitoring window events and process
      outputs.  Although the new one is more efficient and works fine
      as long as I tested, it is not enabled by default in case it may
      cause unpredictable results because it spawns a thread for
      monitoring sockets.  To enable it, specify
      `-DSELECT_USE_CFSOCKET' for CFLAGS.
