\pdfoutput is normally nowaday always defined. You need to check its
value to see if you are outputting dvi or pdf

So you need something like

\ifnum\pdfoutput<1
  \special{papersize=\the\totalwidth,\the\totalheight}%
\else 
  \pdfpagewidth=\totalwidth
  \pdfpageheight=\totalheight
\fi  

Be aware that a \special must be issued on a page, you can't do that
in the preamble. In LaTeX the special is in \AtBeginDvi.

It you want to support also xetex and luatex you need a few more
tests.
