This works on gcc3.3 and gcc4.0 (OSX) but doesn't compile on vc8.0
I'm wondering whether it should and I've just messed up somewhere
installing boost 1.33 or vc8 (VS 2005). I noted that the regression
test does not perform this form of disconnect, is that the manual
telling me this isn't supported? I get a very similar error if I try
a functor (using bind) rather than example below ~ "can't convert to
'const int'". There's some comments in signal_template.hpp that
indicate vc 6.0 and 7.0 have problems with this, maybe that #ifdef
needs to include vc8?
cheers,

#include <iostream>
#include
void rfun()
{
std::cerr << "Hello World\n";
}
int _tmain(int argc, char* argv[])
{
boost::signal sig;
sig.connect(&rfun);
sig.disconnect(&rfun);
return 0;
}
