Under FreeBSD (on my 2.1.5) the dc is the GNU dc 0.2 version. If I remember
well, there is a newer 0.3 version, included in the GNU bc package. Maybe
it works well (if it is, this is the reason, why some Linux systems
generate the xyz..., the others the Get life string.) Are there anybody,
with the newer GNU bc who can try it?
And another one: it reminds me to one of the winners of IOCCC, korn.c:
main()
{
printf( &unix[ "\021%six\012\0" ], (unix) [ "have" ] + "fun" - 0x60 );
}
Well, this cannot even compile on AIX systems - their ad's: The world's best
UNIX! Of course, we can compile and run it on FreeBSD, and on most of the
UNIX machines, I've tried (most of them were mainly SysV).
