# Conflict: kluwer and amsmath

When I try to use the document class kluwer together with amsmath there seems to be a conflict. Is is possible to avoid this conflict?

I have tried to add \let\iint\noexists before loading amsmath as suggested in http://groups.google.com/group/comp.text.tex/browse_thread/thread/b57ac7fcbffa5120/9afe4da0cacfffdf but that doesn't help.

Here's an example. The following

\documentclass{kluwer}

%\let\iint\noexists
\usepackage{amsmath}

\begin{document}

Bla bla bla

\end{document}


gives the following error

ERROR: LaTeX Error: Command \iint already defined.

For me, a minor modification of the linked fix works:

\documentclass{kluwer}

\let\iint\undefined
\let\iiint\undefined
\usepackage{amsmath}

\begin{document}

Bla bla bla

\end{document}


You need to undefine both \iint and \iiint (count the is!)
