On http://gcc.gnu.org/gcc-3.0/criteria.html, Debian 2.1 is listed as primary evaluation platform for i686-pc-linux-gnu. - This should be Debian 2.2, which is currently frozen and will be released this year (although a date is not yet known). - Currently Debian ix86 is built for i386-pc-linux-gnu. - Is the alpha architecture omitted by intent (it's listed for RedHat). - Same for the Sparc secondary platform, where RedHat is mentioned explicitely.
