# autonum breaks align* and equation*

The autonum package apparently doesn't like me to declare math modes to be unnumbered, and prefers to do this on its own. Can't really tell if this is intended behavior and if so, why.

\documentclass{article}
\usepackage{amsmath}
\usepackage{autonum}
\begin{document}

\begin{align*}
x &= a+b
\end{align*}

\end{document}
