--- Comment #4 from Peter A. Bigot <pab at pabigot dot com> --- If you mean how did OpenEmbedded configure the compiler that's being used for the bootstrap, that's an uglier question that I can't really answer since it's got various patches and special stuff involved. The only reason I'm bootstrapping the released 4.9.1 at all is to determine whether a C++11 issue is due to OE patches; I didn't expect to run into this particular problem, which appears to be a fragility in the bootstrap when using the newly built compiler with the system headers from the originally build compiler.
