bordermatrix with thinner columns

I'm trying to set-up the column width of a bordermatrix with the usual \setlength{\arraycolsep}{0pt} command (usual in the sense that it works for usual matrices) without success: what should I use instead?

-

\quad is used as seperator.

\documentclass[12pt]{article}
\begin{document}

$\bordermatrix{% & 0 & 1 & 2 \cr 0 & A & B & C \cr 1 & d & e & f \cr 2 & 1 & 2 & 3 \cr }$}

\end{document}
