For about half a year ncurses has a "--with-versioned-syms" configure option that enables symbol versioning. We should use this option in the upcoming ncurses 6.0 release and rebuild all reverse dependencies before the Stretch release so that we can switch to the new ABI afterwards. When using this option, quite a lot of internal symbols which are not part of the API are no longer exported, see the attached list. Fortunately according to codesearch.debian.net, very few packages seem to use any of those symbols: - fpc, in fpcsrc/packages/ncurses/src/form.pp, apparently declares _nc_Default_Form and _nc_Default_Field. Probably nobody really uses those, but I don't really have a clue of Pascal. - cmake has a lot of hits since it includes a very outdated copy of the form library which is apparently unused. The /usr/bin/ccmake binary from the cmake-curses-gui package is linked with the system form library and does not use any private symbols from it. - libncursesada and haskell_ncurses declare _nc_has_mouse, but only if NCURSES_VERSION_PATCH < 20081122. Prior to that date, _nc_has_mouse was actually part of the API so its removal might break some old programs. This might be a case where the symbol should actually be exported in order not to break the ABI.
