Subject: Re:  Bug with anonymous unions and bit-fields

Wow, So there is a diff inside and outside a struct? 

This is very counter-intuitive but I am  to accept your explanation if that's
what the language says. 

Thanks so much for looking into it and responding. Sorry if it is not a bug, I
googled for anything similar before filing it.
