encounters the math display with \=:

\documentclass{amsart}
\AtBeginDocument{%
\makeatletter
\renewcommand*\@aciii{\mathbin{\,=\,}}
\renewcommand*\={\@aciii}
\makeatother
}
\begin{document}
$A\= B$
\end{document}

The funny thing is that just adding the @-code after \begin{document}
yields the error \@aciii undefined''.

But works fine on my 600-page document.
