I used to think that this:

but it is not, in a subtle way.
This is likely a gcc bug isn't it? The gcc info page states:
Specifying this attribute for `struct' and `union' types is
equivalent to specifying the `packed' attribute on each of the
structure or union members.
A gcc *documentation* bug?
I asked on the gcc list about this before posting here, and although
replies are still coming in the first opinion was "it's doing exactly
what you asked it to do".
