no, it's a feature.  The headers are in a subdirectory to make it simple
to avoid including /usr/include/curses.h

Portable applications that use ncurses would either have two -I options
or have some ifdef to switch between these cases:

        #include <curses.h>
        #include <ncurses/curses.h>
        #include <ncursesw/curses.h>
