Cute. I had not known of perror(1) (perror(3) has been around for
perhaps 25 years).
perror(1) is part of the mysql-server package so not all folks have it
installed.
$ type perror
perror is /usr/bin/perror
$ rpm -qf /usr/bin/perror
mysql-server-4.1.12-2.FC4.1

Right. The internal kernel functions tend to use negative errno(3)
values to indicate failure. These sometimes leak out into messages, as
in this case. errno(3) values themselves are strictly positve (0
means "no error").
I never knew it was included with mysql. I created one for my
3B1 (yes a long time ago) and I've always had it. It's simple
enough, you're just passing a number to the function perror. :-)
