Can we abstract this kind of thing into

DISPLAY_GRAPHIC_P=no

test "${HAVE_X11}" = "yes" || test "${HAVE_NS}" = "yes" || \
  test "${opsys}" = "mingw32" && DISPLAY_GRAPHIC_P=yes

if test "${DISPLAY_GRAPHIC_P}" = "yes"; then...

Sometimes it seems to be test "${HAVE_W32}" = "yes" instead, so maybe
there are not enough common patterns for it to be worthwhile.
