[XeTeX] geometry.sty FIX for XeTeX 0.994

[Will Robertson]

Hello,

People have run into some unfortunate coding in the geometry package  
that assumes only pdfTeX uses the \pdfpagewidth command. This results  
in an error compiling a previous-working document.

Use the following to temporarily fix the problem until geometry is  
updated; note that it works whether the document is typeset using  
either the XeTeX or pdfTeX backends:

   \ifdefined\XeTeXversion
     \newcount\pdfoutput
     \pdfoutput0\relax
   \fi
   \usepackage[dvipdfm]{geometry}

(Actually, the [dvipdfm] option might not be necessary...not sure,  
really.)

Hope this helps,

Will
