Maybe this can > be added to the FreeBSD Jenkins instance now? Thank you *very* much, Dimitry. For the informative reply. Yes. I agree, adding a task for Jenkins seems like a *very* good idea. Well, it looks like a real gamble not going with defaults, for now. I guess attempts using gcc as base compiler is off the table, for now. This must really hit some of the other ARCHS pretty hard. I can't imagine trying to develop under these circumstances. Here's hoping for improvements in this area soon! Thanks again, Dimitry. --Chris > > -Dimitry
