There are way to many predicates out there to introduce direct library support 
for each one. The recomendation is to use generic predicate support instead.

Not equal check can be done either using STL functors by 

BOOST_CHECK_PREDICATE( not(equal_to), (a)(b) )

or using lambdas by 

BOOST_CHECK_PREDICATE( _1 != _2, (a)(b) );
