got the same problem

[Marshall Clow]

Boost.Signals is being deprecated. Please transition to Boost.Signals2

[johannes@…]

The problem is with typeof, not signals. I dont know whether that still occurs though. Defining BOOST_TYPEOF_SILENT was a leftover from earlier boost versions which would be quite verbose wrt to typeof details. Might as well be irrelevant now.
