Building with curses is, according to Paul Eggert:
"Completely broken" in the sense it won't link and Emacs won't build,
yes. (It will link in master, due to a patch I installed recently.)
And yes, the original curses library has been obsolete for at least two
decades.
See the discussion here:
https://lists.gnu.org/archive/html/emacs-devel/2021-01/msg00416.html
The conclusion from that thread AFAIU is that support for curses
should be removed. (We should keep ncurses though.)

Doesn't that mean we will be removing support for AIX (and any other
systems that cannot use ncurses due to the same problem)? Are we
willing to drop support for those platforms because of curses? AFAIU,
the original problem was fixed, and there's no longer a link error
when using curses.
In any case, if we are planning to drop support for curses, we need
to obsolete it first, i.e. add a configure-time warning for that.

Yes it does mean that, at least, on AIX systems without any of the other
terminal libraries installed.

That's right. So I guess we should keep curses support, for the odd user
still running Emacs on AIX. Sorry about any confusion on the topic.

If curses support is actually needed for some systems
which people still run Emacs on, and it does work on those
systems, there is no need to delete it.
