The ABI reflects how your executable interfaces with the ncurses
library; whether your application uses ABI 6 depends entirely on what
your distro provides.

The API reflects what functions your can call in your source-code. As
far as I know, you should check for NCURSES_EXT_COLOR before assuming
you can draw more than 16 foreground or background colours;
NCURSES_EXT_FUNCS before assuming you can use any ncurses-specific APIs
like use_default_colors() or init_extended_pair(), and
NCURSES_MOUSE_VERSION >= 2 before assuming you can receive scroll-wheel
events. There may be others.
