Obviously, distributors can do whatever they please, but the C++

As far as I'm concerned, I totally agree on both accounts. Maybe was not
clear in this thread, but I sent the original message to point-out a
*bug*, which had to be fixed, and quickly. To be safe, while waiting for
the fix, I even reverted completely the new feature.
Now the C++0x feature is back in, provided only for target implementing
the atomic builtins unconditionally: it works that the corresponding
declarations do *not exist* in <exception> if the prerequisites are not met.
