the development version (afaik) builds with either - though I have no 10.x
system to verify this.  (Lynx's source-code can be built with either a
K&R or ANSI compiler).

there's more than one version of HP curses as delivered (the default one,
I'm told, is the one with a broken 'select()' call - but Hcurses and
curs_color may also work).  You need an ANSI compiler with ncurses,
but I don't know about the others.

a little better, perhaps, (uglier but handles more than apollo):
#ifdef S_IFSOCK
# ifdef S_IFIFO
                        case S_IFSOCK: type = 's'; break;
#  endif
# else
                        case S_IFSOCK: type = 's'; break;
# endif
