Why not just name the function jot() so we don't have to change all
calls?

I maintain a separate FreeBSD port.
https://cgit.freebsd.org/ports/tree/devel/got

In fact, the -portable people may want to take a look at that for
an overview of problems I have solved there and how I did it:
- I use sed to insert
  #include "openbsd-compat.h"
  into all *.[cy] files between the #include <...> and #include "..."
  headers.
- There are various compatibility headers/wrappers.

I also recommend looking at OpenSSH for a template for the whole
autotools stuff.

I would happily merge the FreeBSD changes into -portable, eventually.
There was a long break where no work at all was happening in
-portable, and the next few weeks I'll be very short on time.
