Except it's not a final std yet?

Oooo, power :-)

OK there are a couple of outstanding issues:

* We need test cases for the new macros.
* The config-tools (the configure script and the small generator program
under libs/config/tools that updates the test driver and
config_test.cpp+config_info.cpp) assume that the macros are named BOOST_NO_*
or BOOST_HAS_HAS_*, without that they don't work :-(

The general proceedure for new macros is documented here:

So could you either use BOOST_HAS_* or else modify the script
and the generate.cpp program to do the right thing?

Many thanks,
