Trying to use the new random library on borland gives runtime problems.
The following program below gives a constant result of 85.
I have tracked the problem to variate_generator.hpp, where the internal engine type is computed
typedef typename random::detail::engine_helper<have_int, want_int>::BOOST_NESTED_TEMPLATE impl<decorated_engine, typename Distribution::input_type>::type internal_engine_type;
In the example program it is using uniform_int_float instead of uniform_01 (engine_helper<false,true> instead of engine_helper<true,false>)
I could patch the engine_helper to work using mpl::bool_, but the dependency is probably not wanted?
