When trying to use the foreach library, whether running it tests or trying to build quickbook which uses the foreach macro, I am seeing from different compilers:

Does anybody know what is causing this error ? I can't seem to proceed in building documentation with quickbook until I can get foreach working. I pulled the latest foreach from the master branch and ran b2 headers but still the problem occurs.
This comes from my testing of type_traits Version2. Sorry for the noise <g>.
