Re: [boost] Signals (& Slots) library updated

The following does not compile on Borland C++. I am getting very confused by
all the macros in signal_template.hpp, any idea what the problem is?

#include <boost/signal.hpp>
#include <iostream>
#include <string>

struct testSig {
    void operator()(std::string x)
    {
        std::cout << x << '\n';
    }
};

boost::signal<void, std::string> sig;

int main()
{
    sig.connect(testSig());
    sig("hello");

    return 0;
}

Error E2034
C:\PROGRA~1\Borland\CBUILD~1\Bin\..\include\boost/signals/signal_template.hp
p 217:
