ncurses has a configure option that adds a few more consts to its
headers by way of the NCURSES_CONST define. Starting with version
6.0, this has become the default. OpenBSD is still on ncurses 5.7,
but FreeBSD and I guess most Linux distributions have moved on.
I suggest we also enable the additional consts. This eliminates
compiler warnings when sharing code with other platforms.
The diff below has successfully gone through a release build on
amd64, as well as a full amd64 package build.
OK?
