Hi!
It seems that Boost.Accumulators is broken for all msvc builds with error messages like:
boost/accumulators/framework/accumulators/reference_accumulator.hpp(72) : error C2061: syntax error : identifier 'BOOST_PP_CAT' boost/accumulators/framework/accumulators/reference_accumulator.hpp(72) : fatal error C1903: unable to recover from previous error(s); stopping compilation
(from http://www.boost.org/development/tests/develop/developer/output/teeks99-02e-...)
The regression page http://www.boost.org/development/tests/develop/developer/accumulators.html shows _all_ msvc builders failing.
My own code broke with an identical message sometime last week.
Any ideas?
I think there's a missing #include <boost/preprocessor/cat.hpp> in boost/accumulators/accumulators_fwd.hpp. There is another use of BOOST_PP_CAT in boost/accumulators/numeric/detail/function_n.hpp but it has the #include. I don't see how this could be related to boost/accumulators/framework/accumulators/reference_accumulator.hpp though.
