OK, thanks to Sebastian and Nat, plus some Google group searches, I found a 
solution, which is, in a nutshell - #define BOOST_BIND_ENABLE_STDCALL:

Here is a sample:

#include <windows.h>
#include <string>
#include <vector>
#include <algorithm>
#define BOOST_BIND_ENABLE_STDCALL
#include <boost/bind.hpp>

int _tmain(int argc, _TCHAR* argv[])
{
 using namespace std;
 using namespace boost;

 vector<wstring> v;
 v.push_back(L"test.txt");
 for_each(v.begin(), v.end(), bind(&DeleteFileW, bind(&wstring::c_str, 
_1)));
 return 0;
}

Without enabling BOOST_BIND_ENABLE_STDCALL, the bind on ::DeleteFileW would 
fail.
