Comment (by barendgehrels):

 After doubting about this one, and looking at other Boost.Libraries, it is
 indeed probably the best to use #pragma's here. Many libraries do the same
 for the same problem.

 Alternatives were rewriting (too much), or declaring local non-const
 variables to avoid this warning (I considered this as too much workaround
 for this message only, and this has a (though small) performance penalty)

 So pragmas are added yesterday.
