Ugh, those come from an archaic bodgy reimplementation of half of
termcap or something.

Try installing the ncurses development files (libncurses5-dev on
Debian-type systems, for example), or terminfo development files, or
something like that, so you get the system's termcap/terminfo/whatever
library instead?

(We should maybe just delete tparam.c and termcap.c and make the
system termcap/terminfo mandatory...)
