work in progress patch for this case

 * this is not finished (needs to be conditional on a compatibility flag)
 * might not be acceptable upstream (depending on whether other maintainers are
willing to accept clang extension work-arounds). 

However, AFAICS this 'extension' would affect all targets if they were
presented with such input (so that this is not actually a Darwin-specific
problem) - it's just that we see it in the headers.

The patch is against recent master, but I'd expect it to apply reasonably
easily to 12.1, 11.3 and 10.x.
