Identifiers that start with '_' are illegal at file scope per 188.8.131.52.2.
I think that the best way to tackle the problem is to leave
boost/bind/placeholders.hpp as it is. You are free to #define
BOOST_BIND_NO_PLACEHOLDERS and use your own placeholders.hpp with whatever
definitions are appropriate in your case.
