The old system just came back online so I checked and GCC 3.4.6 (the oldest version I have, released Mar 06 2006) is able to bootstrap c,ada for 4.3.2 release (2008-08-27) on Linux i686. So at least 3.4.x is able to build 4.3.x with Ada enabled on Linux. I will build and test ability of 3.4.0 (released Apr 18 2004) to 5 to bootstrap 4.3.x in the coming weeks. Hope this helps, Laurent
