But try to link it with your curses first - and then with ncurses. My former
post was telling about executable using ncurses.
Yes, when using your curses, it seems to work a bit better in NetBSD's
environment. Are ncurses not quite compatible with NetBSD?

I have added raw() immediately after initscr() - but I wasn't sure, is it
the proper way.

Right. Found it too. Shouldn't it just dispose of all the subwindows,
when "parent" is already deleted? (even without a need to delete
sub-windows separately...)

Found another thing: it seems, that subwindows (in NetBSD's curses) cannot
"inherite" properties (like back-/foreground colour, for example) of the
"parent" windows. Look at that "draw_menu" procedure - before
wbkgd(items[1],COLOR_PAIR(4)); (which shows the position of "higlight tab"),
I had to add:
for (i=1;i<9;i++) {
wbkgd(items[i],COLOR_PAIR(2));
}
...just to set color pair for each subwin separately - although a few lines
earlier there was:
items[0]=newwin(10,19,1,start_col);
wbkgd(items[0],COLOR_PAIR(2));
So, the "parent" window has been set - but "children" forgot the settings.
Is it a bug - or feature?
