Well, in Debian/Ubuntu are _two_ dev packages, one for the wide API
(libncursesw5-dev), and on for the non-wide API (libncurses5-dev).  Only
the latter should be necessary, but with your original patch people
would need to install the former as well.

That seems unlikely to cause regressions on its own.
