The question is not just one for bootstrapping a native compiler but also one of what compiler can be used to build a cross compiler (such as that with multiple targets), which is not bootstrapped in the usual GCC sense. There we presently document GCC 2.95 or later as required (and again I think requiring a version later than 4.1 would be a bad idea). -- Joseph S. Myers jos...@codesourcery.com
