Make buildable under FreeBSD.
This one's a real mess. It's full of undefined macros, and in one
place deliberately causes syntax warnings. I've decided against
taking out the undefined macros: they don't alter the format of the
output document, and maybe one day somebody will put in the macro
definitions.
Note that this file corrects a number of format errors which appear in
the O'Reilly 4.4BSD manual set.
