 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
 Lou
