[Boost-users] BOOST_CHECK_EQUAL compiler warning

I get a compiler warning when using BOOST_CHECK_EQUAL in conjunction with BOOST_AUTO_UNIT_TEST.  The code and warning are below.  Anyone know what I'm doing to cause the warning?

Environment:  Windows XP with MS VS 2003

#define BOOST_AUTO_TEST_MAIN
#include <boost/test/auto_unit_test.hpp>

class MyTest
{
public:
    MyTest( int newVal = 3 ) : a (newVal) {}
    int GetA() {return(a);}
protected:
    int a;    
};

MyTest  test1;

// _____________________________________

BOOST_AUTO_UNIT_TEST( TestCase1 )
{
    int b = test1.GetA();
    BOOST_CHECK_EQUAL( b, 1 );
}

The warning is:
