If I use ncurses instead, all is fine until the final linking; I then
get errors that 'wechochar' and 'intrflush' are 'undefined references.'
(And sure enough, if I check the man pages, I find excellent documentation
on those two functions, as well as a footnote that says "these haven't
been implemented yet.")
The version of ncurses, by the way, is 1.8.5.
Thanks,
Steve
