I presume from your previous message that you're using AIX (it always helps
to know that sort of thing).  In that case, this may be an ncurses problem:
in fact, I see the same thing.  What's happening in my case is that
termcap.h is found in /usr/local/include, where it comes from ncurses;
this is being included and defining NCURSES_VERSION, which messes things up
in bin_echotc().  You can check this by looking to see if HAVE_TERMCAP_H
is defined in config.h.  If it is, try changing the line to
/*#undef HAVE_TERMCAP_H*/
and recompiling.

Does anyone know if ncurses is 100% guaranteed to fail on AIX, given that
the search order for libraries puts curses before ncurses?  If so, then
the following patch would be OK.  (We're stuck on AIX 3.2.)
