   And/or both could be stubbed out easily enough;  i.e.,  if you want 
to use those libraries with PDCurses*,  you add

SCREEN *_nc_screen_of( WINDOW *unused_pointer)
{
   return SP;      /* the only screen PDCurses* currently has */
}

size_t _nc_wcrtomb( char *s, wchar_t wc, mbstate_t *ps)
{
    return wcrtomb( s, wc, ps);
}

   to your code (maybe modifying the second function on some 
platforms),  and... you're done?

   Warning taken,  but this does look as if it may be much more 
straightforward than I'd thought.  With the above trickery,  it would at 
least appear the libraries can be used unaltered... which would be 
amazing.  I'll give it a try and see what explodes.

Thanks!           -- Bill
