Actually, I didn't look closely enough, even after Mark's answer.
This is already dealt with, so we can remove this one as well.
So I'm suggesting this patch instead (which such scraps the alloca
#pragma in addition to what the previous patch was already removing).

Is this OK?

(the only little detail is that I am not sure I can verify this works
or not. I'll see what I can do).
