But look at the code in builtin.c.  puts("no"); near line 4193 is compiled
iff NCURSES_VERSION is defined.  I did compile zsh on SunOS 4 and echotc
works for me (without ncurses).  If one is not careful enough when
installing ncurses, ncurses installs termcap.h which will be used instead
of the system termcap.h which will cause problems with other applications
as well not only with zsh.  Are you sure that the included termcap.h does
not come from ncurses?
