After upgrading MiKTeX from 1.20c to 1.20e, I noticed that TIFF files
were no longer converted correctly by dvips.  I've reproduced this
problem on both Win98 and WinNT4.  I found that if I replaced 1.20e's
dvips v5.86 with 1.20c's dvips v5.83, everything works fine.

Is some additional configuration necessary to cause dvips 5.86 to call
tifftopnm and ppmtobmp to convert and embed TIFF files in PS output?

Here is an example TeX file, named foo.tex on my system:

====================
\documentclass{article}
\usepackage[dvips]{graphicx}
\DeclareGraphicsRule{.tif}{bmp}{}{}
\begin{document}
\includegraphics[width=0.73in,height=0.65in]{bar.tif}
\end{document}
====================
Converting with dvips 5.83 (after running `latex foo', of course):
