Hi Richard,

Frankly I do not follow what you want exactly. BOOST_REQUIRE reports a location
of that statement. What do you want to report? 

It might be that you want something like this:

void check_op1( char const* f, int l )
{
    BOOST_REQUIRE( expr, f, l );
}

BOOST_AUTO_TEST_CASE( t1 )
{
     check_op1( __FILE_, __LINE__ );
}

BOOST_AUTO_TEST_CASE( t2 )
{
     check_op1( __FILE_, __LINE__ );
}

If this is the case, I'd rather you use new BOOST_TEST_CONTEXT facility and
implement check_op1 like this:

void check_op1( char const* f, int l )
{
    BOOST_TEST_CONTEXT( "Testing invoked from: " << f << "(" << l << ")" ) {
        BOOST_REQUIRE( expr1 );
        BOOST_REQUIRE( expr2 );
    }
}
