--- Comment #1 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-04-28 19:51:56 UTC --- Currently the library itself, its *.cc files, are not meant to be all built in c++0x mode (the Makefile carefully builds some in c++03 mode and some in c++0x mode). Thus, even if somehow one of these days it apparently works please do *not* trust what you get, at minimum the abi compatibility could be broken. Maybe that could change, but not soon, I'm sorry, the priority of the task is quite low (compared to the other)
