You'll probably want to introduce and use an ARRAY_SIZE macro, like
we've been doing in several other places. Chances are it will become
globally available fairly soon. I'd also argue for making integers
unsigned unless there's a reason to make them signed.

"debugstr_a(name)"

Also pretty minor, but "else" and "!func" are redundant here, since
we'd have returned above for any non-NULL "func".
