You may do this simply, this way:

\begingroup\expandafter\expandafter\expandafter\endgroup
\expandafter\ifx\csname pdfoutput\endcsname\relax\newcount\pdfoutput\fi

This may be some chars more but you'd have only one then- and (not in this 
case) one else-part. So the mistake changing only one of them can't happen.
