Milestone:  Boost 1.54.0                         |  Component:  signals2
  Version:  Boost 1.54.0                         |   Severity:

-------------------------------------------------+-------------------------
 My current boost version is boost_1_54_0_beta1.

 In the signals2 component, there is two 'extra ";"' warnings with the
 -pedantic option under g++ 4.7.2 compiler.

 In the boost\signals2\signal.hpp line 58:


 {{{
 // free swap function, findable by ADL
 template<typename Signature,
   typename Combiner,
   typename Group,
   typename GroupCompare,
   typename SlotFunction,
   typename ExtendedSlotFunction,
   typename Mutex>
   void swap(
    signal<Signature, Combiner, Group, GroupCompare, SlotFunction,
 ExtendedSlotFunction, Mutex> &sig1,
    signal<Signature, Combiner, Group, GroupCompare, SlotFunction,
 ExtendedSlotFunction, Mutex> &sig2)
 {
   sig1.swap(sig2);
 };
 }}}

 In the boost\signals2\detail\signal_template.hpp line 740.


 {{{
 #ifdef BOOST_NO_CXX11_VARIADIC_TEMPLATES
     // free swap function for signalN classes, findable by ADL
     template<BOOST_SIGNALS2_SIGNAL_TEMPLATE_DECL(BOOST_SIGNALS2_NUM_ARGS)>
       void swap(
         BOOST_SIGNALS2_SIGNAL_CLASS_NAME(BOOST_SIGNALS2_NUM_ARGS)

     {
       sig1.swap(sig2);
     };
 #endif
 }}}
