The binary dates back to 386BSD 0.0, and I'm only keeping it out of curiosity: j@uriah 66% ls -l /usr/local/bin/utree -rwxr-xr-x 1 bin bin 179639 Apr 30 1992 /usr/local/bin/utree* The only thing to make it run is to use a termcap entry that is smaller than 1024 byte, as this used to be a hard-coded limitation in the termcap library of those days, and the binary is statically linked. TERM=vt100 works, xterm no longer does. The ability to run this binary only serves as a proof that no backward compatibility has ever been broken in FreeBSD. ;-) (Obviously, all the various COMPAT_* options must be present in the kernel config.) -- cheers, J"org .-.-. --... ...-- -.. .
