As you can see here, we have now a working Windows tinderbox. It finished tonight its first successful build of master branch and will send you nagging e-mails for any breakages from now on. It is our hope that this tinderbox will help us to keep LibreOffice buildable on Windows much easier.
This tinderbox is running Windows Server 2008 R2 Service Pack 1 with Visual Studio 2008 Service Pack 1 and Windows SDK 7.1. The server was graciously given at the disposition of the LibreOffice community by the French town of Voreppe through the association La Mouette. I want to personally thank Laurent Godard, a long-time community member and contributor who was more then instrumental in this transaction.
