RE: MSVC++, bind and namespaces

Hi,
FYI, the code below compiles and runs OK on MSVC++7... so you might just be
right! 
 
Regards,
Antoine

I've just encountered this problem and it looks like a MS bug. Not sure it
deserves a Boost workaround but I thought it would be nice to let you know
(in case you don't already).

Here's the code:

#include <boost/bind.hpp>
namespace A{
        struct c{
                void setName(const char*) {}
        };
}
namespace B{
        struct c{
                void setName(const char*) {}
        };
}
using namespace B;
using namespace A;
int main() {
        boost::bind(&A::c::setName, _1, _2);
        return 0;
}

It looks legal to me but I'm no expert. GCC compiles with no warnings but
MSVC++ 6sp5 gives the error below.

boost/bind/mem_fn_vw.hpp(29) : error C2872: 'c' : ambiguous symbol
        boost/bind.hpp(875) : see reference to class template

Best,
