Alternatively you can just bootstrap GCC under test natively first and then use the newly-built compiler for all the cross builds you want to verify. As you need to do it only once per iteration the extra time spent on the native build shouldn't be a big fraction of the duration of the whole iteration. A drawback is if this native bootstrap fails for any reason, it will make the whole run invalid, i.e. none of the cross targets will be verified. Maciej
