portability issues wiki   (link)

http://www.flamingspork.com/portawiki/index.php/Main_Page
A Wiki for the collecting, sharing and collaboration on portability issues that arise during software development and porting. There are entry points per topic and per platform. Please contribute what you know/find and help build this essential resource!

The idea for this came up at AUUG 2005 in Sydney, originally by Peter Gutmann (cryptlib). People from MySQL AB and the OpenBSD / OpenSSH project immediately responded positively, so Stewart Smith set up this wiki to get things started.
