This looks like a bug to me.  There have been some significant changes
to the bit-field support over the last few years.  There were some cases
where we were non-conforming with respect to C89: getting sign/zero
extension wrong, performing operations with the wrong precision.  Plus
some changes were needed for C99 support.  It looks like these changes
have accidentally broken the -Wformat support.

Just taking a quick look, I don't see any existing bug report for this,
so I created a new one.  This is now FSF gcc bug 22421.
