This reverts commit 953c9fcf8c1a2e0cbebadd9c07591caed7d26f8a. It turns out that most packages (guile-ncurses, cursynth, aumix, util-linux, etc.) expect libncurses to provide everything. So they had to be patched to add -ltinfow to their LDFLAGS, which is counterproductive. Other recent distros take that approach---e.g., <https://bugs.launchpad.net/ubuntu/+source/ncurses/+bug/259139>.
