[pdftex] Hyperref, pageanchor, and titlepage

[Patrick Riley]

This is a minor problem I have encountered using hyperref with
pdftex. I have a workable solution, but it seems a little ugly to me,
and if there's a better way to do it, I'd love to hear about it.

I have a document for which I want to use page anchors so that the
table of contents is hyperlinked. The document also have a title page,
using the titlepage environment from the article class. If I have this
file:

\documentclass[notitlepage]{article}
\usepackage[debug,pageanchor=true]{hyperref}
\begin{document}
\begin{titlepage}
  Title page
\end{titlepage}
Some text
\end{document}

I get this output:

What's going on is that the titlepage environment sets the page number
to 0 so the first real page comes out as 1. But it's too late at this
point because we already have the page.1 link. I tried all kinds of
combinations of setting the page counter before and after the
begin{document}, with \AtBeginDocument, etc and nothing
worked. 

Finally, doing this makes it all work, but it's a little weird.

\documentclass[notitlepage]{article}
\usepackage[debug,pageanchor=false]{hyperref}
\begin{document}
\begin{titlepage}
  Title page
\end{titlepage}
\hypersetup{pageanchor=true}
Some text
\end{document}
