Check the option flags whether the new or old legacy behaviours are
wanted.

For _MSVCR_VER < 140, don't check the option flags but hardcode them to
TRUE. (This avoids having to manually add all three flags into every
caller of pf_printf.) Mask out any other flags, to avoid other
out-of-range flags to be interpreted as the other flags (positional
params, invoke invalid param handler).
