+/*  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
