Thats not an issue for ncurses because Include/py_curses.h does:

  #ifdef HAVE_NCURSES_H
  /* configure was checking <curses.h>, but we will
     use <ncurses.h>, which has all these features. */
  #ifndef WINDOW_HAS_FLAGS
  #define WINDOW_HAS_FLAGS 1
  #endif
  #ifndef MVWDELCH_IS_EXPRESSION
  #define MVWDELCH_IS_EXPRESSION 1
  #endif
  #endif

So it overrides WINDOW_HAS_FLAGS for ncurses case.
