[texhax] pdflatex \neq latex + dvipdfm

[Michael Barr]

The following file produces different output when run through pdflatex 
and latex followed by dvipdfm:

\documentclass{slides}
\textwidth 9in
\oddsidemargin 0in
\textheight 6.2in
\topmargin -0.5in
\headsep 0in
\headheight 0in
  \footskip .6in
\special{landscape}
\usepackage{lipsum}
\begin{document}
\lipsum
\end{document}

The output is not different if the line \special{landscape} is removed. 
It is the latex + dvipdfm that produces the output I want.  This may also 
depend on the viewer.  I think that the adobe viewer showed the wrong 
thing in any case, but it also hung up my computer and I have deleted it 
and replaced it by sumatrapdf.
