And the definition of __DARWIN_ALIGN32()?

It looks like the definition is not properly resulting in a compile-time
constant, and therefore the warning about the initializer is resulting
because you can't initialize a dynamically-sized array.  But you still
haven't shown us why the headers are resulting in a non-constant size.
