This is actually the reason to not even try to compile my ktaglib extensions under Windows. Well but this approach is doomed to fail as most of the developers out there use Windows as their operating system. [...] So actually I ended up booting up windows again (well after searching for the harddisk that contains a running windows) and try to compile it. Otherwise my fellow collegues wouldn't be able to fix my buggy PHP code.

He talks about the pecl2 updates and how it makes compiling on a Windows system easier than before and two resources that budding Windows extension developers can use to get started - the PHP.net wiki and a screencast from Elizabeth Smith that can help out quite a bit.
