Is there a technical limitation preventing this from working?

int __stdcall VirtualUnlock(void*, size_t);

void f()
{
    std::list<void*>  locked_buffers;
    size_t size;

    std::for_each(locked_buffers.begin(), locked_buffers.end(),
        boost::bind(VirtualUnlock, boost::lambda::_1, size));
}

Irrelevant code snipped for brevity.  I get the error

It complains about how it can't find F::result_type in
bind_template.hpp line 15, with F = int (__stdcall*)(void*, size_t)

If I change it to

int __stdcall VirtualUnlock(void*, size_t);

void f()
{
    std::list<void*>  locked_buffers;
    size_t size;

    std::for_each(locked_buffers.begin(), locked_buffers.end(),
        boost::bind(boost::function<int(void*,size_t)>(VirtualUnlock),
boost::lambda::_1, size));
}

it works, but this is much uglier and I'd rather avoid it.
