13627	"""bcp --namespace=..."" misses change in macro for ""unordered""."	Lou Barbieri <louis.barbieri@…>	John Maddock	"Boost version:  1.67.0

Steps to reproduce given below error message.

Hello,

I'm using bcp to put all of boost under a new namespace.  bcp completes ok, but compilation of the new tree gives the following error (repeats several times - first instance shown):

Steps to reproduce:
{{{
unzip boost_1_67_0.zip >/dev/null
cd boost_1_67_0/
./bootstrap.sh --without-libraries=python
./b2 tools/bcp
mkdir -p ddt
./dist/bin/bcp --namespace=ddtboost bin.v2 boost libs more status tools ddt
cd ddt
./bootstrap.sh --without-libraries=python
./b2 -j4 --build-dir=build --without-python --layout=tagged variant=release link=shared threading=multi runtime-link=shared
}}}

Changing the third parameter from {{{boost}}} to {{{ddtboost}}} in the calls to {{{BOOST_UNORDERED_CONSTRUCT_FROM_TUPLE()}}} starting at lines 1606 and 1695 fixed the issue (given my --namespace).

I've attempted to attach a patch file showing the differences, but chances are outstanding I screwed it up.

If I can provide any more info, please let me know.

Thanks
