It doesn't seem to work with default arguments. :-(

Here is my test case (under gcc 4.7.2 -std=c++0x):

#include "boost/type_traits/has_call.hpp"
#include <cassert>

template<typename Sig, typename F>
bool HasCall(F const&)
{ return boost::has_call<F, Sig>::value; }

void DefaultVal(int = 0) {}

int main()
{
    assert(HasCall<void()>(DefaultVal));
}
