By Diaoul:

--enable-overwrite put include files in `include` whereas the behavior without this option is to put it in `include/ncurses`.
So in the C code, you include `panel.h` or `ncurses/panel.h`

Python requires ncurses to be in `include`, some other programs may search for ncurses libraries in `include/ncurses`
