   /*  Note on IntelMac. [2006.06.05]
       SIGINT does not seem to be blocked on the rosetta emulator of ppc
       on the IntelMac's. "ox" should be universal binary.
      A dirty hack to generate a universal binary of ox is as follows.
      (1) Add -arch ppc -arch i386 to CFLAGS in src/kxx/Makefile
          and src/kan96xx/plugin/Makefile
      (2) Build ox
