[fptex] Using color package with pdftex

[Guy Worthington]

With the following tex source code I get an error.

%--------------------------------------------------
\input miniltx
\makeatletter
\def\Gin@driver{pdftex.def}
\input color.sty
\resetatcatcode

\textcolor{red}{a little red}
\textcolor{blue}{a little blue}

\bye

The log file is attached below:

If I comment out the line in pdftex.def which contains the \if@label
commmand, the file will run to completion.

(I think I'm using the latest pdftex.def, it has the following id:
\ProvidesFile{pdftex.def}[2001/09/01 v0.03h graphics/color for pdftex])
