My initial impression was that the code uses them (e.g. ATTRIBUTE_UNUSED).
But OK, actually the first thing I did was a simple "if" in the default
section; I only thought that ranges would be more evident. Alternatively,
we could have a bunch of O_md cases; 32 cases with just a simple break
might be way too much, though. With md_resolve_symbol this makes more
sense, I think.
This might avoid the fatal error, but will still hit an error later

after the switch (including this break).
I think this calls for an

Do you mean letting the caller define this as macro? I suggest calling it
in "default:" section then, with the corresponding ifdef check.
