BTW I did some googling just now and found out that some libraries use a technique they call "CPU probing": just try it and see if you get SIGILL. Is that a bad idea for some reason? Here is a quick hack -- anyone got an ARM system without crc that they could test it on? -- Thomas Munro http://www.enterprisedb.com
