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