And, by the way - by putting the attribute after the 'struct' keyword we
get the best of the two worlds: accidentally non-defined attribute
shortcuts will still result in a build error.
Below is the fix - should be identical to yours (which was whitespace
mangled).
I'll backmerge these fixes to the originating commits & push out -v2 later
today.
Thanks,
Ingo
