Fix from Poul-Henning Kamp and Dima Ruban from the FreeBSD tree, with
changes from Jason Thorpe to not overrun the end of the static buffer

contents of that header (the only file that includes it compiles to the
same object code on multiple architectures with or without including

to the release date.
