Yeah, you're right. I would argue it should just be FLEX_ARRAY for
consistency with other spots, though (in which case add_name_decoration
needs to be updated with a +1).

Running "git grep '^	char [^ ]*\[[01]]' -- '*.[ch]'" shows that this
is one of only two spots that don't use FLEX_ARRAY (and the other has a
comment explaining why not).
