Yes, Nathan and I stepped on each other there.  I think we should keep 
the __extension__ just for clarity; it is an extension, and Jason, 
Nathan, and I have been contemplating issuing a diagnostic, but having 
it be a warning.  It probably wouldn't trigger since this is a system 
header, but I think it's best to leave the marker there.
