[texhax] Badly placed \widehat

My problem is well illustrated by the following file

\documentstyle{article}
\def\bbrack#1{[\![#1]\!]}
\begin{document}
$\bbrack{\widehat c =\widehat d}$
\end{document}

Yes, I could add extra space after the argument, but that is a real 
kludge.  My real question is why can't I get the \widehat to actually be 
centered over its argument.  As you can see, it starts halfway along the 
"d" and ends well to the right.  This is also true of the one on the "c" 
so it is not just centering over an ascender.
