--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> --- Now, Marek, since this is known to fail even with 4.5.0 (with -std=c++0x of course) there is definitely something wrong with your pointing to r180707. I wonder if the fact that before r180707 one couldn't use -std=c++11, had to use -std=c++0x, is somehow fooling your scripts...
