Sorry about travesty, everybody. On all the machines I use, bcmp()
returns a signed value like strcmp(). This assumption isn't portable.

For a quick fix, redefine cmp() in terms of strncmp(), and don't feed
travesty any nulls! Remember that strncmp() and strncpy() take arguments
in the opposite order to bcmp() and bcopy().

I coded cmp() inline in version 1.1; apparently that fixes the problem.
If you're desperate for a copy before Bill reappears, write me.

Yes, Peter, you can replace srandom() and random() by srand() and
rand(). random() and srandom() are two of those annoying routines that
work much better than their predecessors but aren't as widely available;
getopt() is another example.
