Ah! # pragma defineonoption BOOST_CODEGEAR_0X_SUPPORT -Ax

That's a new one to me. Live and learn.

They should be there:


And they did get documented, too:-)

I do need to check the gcc 4.4.x compiler series to make sure we are
covering the features they added after the 4.3 series. And I expect a
stream of C++0x features from all of the compiler vendors over the
next year or so. With both GCC and Microsoft shipping 0x features, the
others won't dare to be left behind:-)
