5722	Compilation error when boost/signals.hpp is included before asio.hpp	anonymous	chris_kohlhoff	"On the [http://lists.boost.org/boost-users/2011/07/69466.php mailinglist] it has been discovered, that including {{{boost/signals.hpp}}} before {{{boost/asio.hpp}}} causes a compile error in {{{asio/detail/impl/signal_set_service.ipp:74}}} saying ''""boost::signal"": use of class template requires template argument list''. 

The following testcase has been used to confirm this under MSVC10:
{{{
#!c++
#include <boost/signals.hpp>
#include <boost/asio.hpp>

int main(int argc, char **argv)
{
    return 0;
} 
}}}

[http://lists.boost.org/boost-users/2011/07/69475.php Igor R] provided the following patch for {{{boost\asio\detail\impl\signal_set_service.ipp:71}}}:
{{{
#!diff
- signal(signal_number, asio_signal_handler);
+ ::signal(signal_number, asio_signal_handler);
