[boost] [exception][mpl] Boost.Exception uses unqualified size_t

The Boost.Exception library uses size_t without any qualification, which leads to unexpected ADL problems related to mpl::size_t. I'm currently not able to provide a minimal use case as I don't fully understand where this happens, but if I replace size_t with std::size_t in boost/exception/detail/object_hex_dump.hpp my problems go away. I tried to look around in other Boost libraries, but all other occurrences of size_t are qualified as std::size_t. Regards Hartmut ------------------- Meet me at BoostCon http://boostcon.com
