pdflatex works fine but latex just won't

Hi. 
I've had problems with latex the last few days. First A file of mine wouldn't
compile. It complained about unfinnished "/fi" statements. While compiling it on
another system with latex installed it worked like a charm and it worked fine
with pdflatex. The kink was at the first if statement in the lines below (which
by the way is a rip of of "The Not So Short Introduction to LaTeX2e"):

\documentclass[a4paper,12pt]{article}
\newif\ifPDF
\ifx\pdfoutput\undefined\PDFfalse
\else\ifnum\pdfoutput > 0\PDFtrue
	\else\PDFfalse
	\fi
\fi
\usepackage[T1]{fontenc}
\usepackage[swedish]{babel}
\ifPDF
	\usepackage[pdftex]{graphicx}
	\usepackage[colorlinks,linkcolor=black,urlcolor=blue,pdftex,%
	pdftitle={ansökan},bookmarks=false]{hyperref}
\else
	\usepackage[dvips]{graphicx}
\fi
