To fix termcap problem:

1. emacs CANNOT use libtermcap.a (libncurses.a) of FreeBSD-4.0.

2. Use following "quick dirty" patch

Comment 2 kaz 2000-05-09 20:17:55 UTC 
It was to change termcap library in FreeBSD 4.0R.

The old version's tgetstr("cm"...) return follows string at xterm.

\E%i%d;%dH

But, new version's it return follows that is likely terminfo format.

\E%p1%d;%p2%dH

The Emacs has 'tgoto' routine in itself that is in tparam.c. This 
routine doesn't support new format. So, We don't use system termcap 
library (Mr.Tomoyuki's patch) or must be modify tgoto routine.

e.g)
