i've done it with SIGWINCH handlers, and then getting the new window size 
coordinates through curses, but it's a pain in the ass. i agree it's not worth 
it.

oh, cool. thanks!  i'll update to netbsd 1.6 and see what happens then.

i'd suggest something like AC_CHECK_FUNC(resizeterm, , AC_MSG_ERROR("your 
curses implementation is too old. please update."))

some time ago, i sent you a quick patch that fixed this . it wasn't perfect, 
but it worked for me, and might just need some cleaning up. i can send it again 
if it is of any use.

thanks again!
