Yes, there's been a bug that I've been unable to track down. Note
that if -std=c++0x option were actually in the user-config.jam file,
then no 3.4.6 test could pass, they'd all fail. Since many 3.4.6
tests are passing while some libraries are failing wholesale, I'm not
sure quite what to make of this. If all of 3.4.6. was failing I could
easily track it down. Since only some of the libraries are failing
with this flag, I'm less clear where to look for the problem. I've
been watching this behavior for some months now, it first appeared
about less than a year ago.
