Pushed, thanks.
I ended up using level 4 and dialling back to 3 for zic.c only
(different make trickery though). I also settled on FALLTHROUGH rather
than FALLTHRU because the latter seems ugly as a spelling to me. I'm
not a fan of the uppercase, but the alternative would be to add a - or
@s.
I get no warnings with this (gcc 8), but ccache seems to save warnings
in one run so that they can be thrown in a later one. I'm not sure what
to make of that, but ccache -d proved that beyond reasonable doubt and
ccache -clear got rid of the lot.
