Pierre-Alain Joye has made an update to his information about building Cairo on Windows with more fixes and the creation of a dedicated page for the project.

I fixed a possible issue with PDF and PS support, it should work way better now. The cairo_build_windows archive has been updated and a decent freetype2 is now included (from gnuwin32). The build system has been tested with VC++ Express and VC.net 2003. Also a configure.bat is now included, it is a simple "alias" for "cscript /nologo configure.js ". You can call it just like any real configure.

As mentioned, a project homepage has been set up for cairo-win32, and can be found here along with some results of it: PNG file, PDF file.
