Dan, I dare you to try this:

// assert_example.cpp
#include <boost/smart_assert_ext.hpp>

void login_admin( const std::string & username, const std::string & passw) {
     SMART_ASSERT( username == "admin" && passw == "secret") 
(username)(passw)
         .msg( "Unauthorized administrator login!");
}

int main() {
     login_admin( "admin", "anonymous");
     return 0;
}

You can get the code from http://www.torjo.com/smart_assert.zip
Also, it's been quite tested on VC6.

Best,
John
