I've added these static assertions in the casting methods:
    BOOST_STATIC_ASSERT(sizeof(cast_type) == sizeof(data_type));
That should guarantee I'm casting an IEEE floating-point number to an
integer of the same size.

Also, using toolset=darwin resolved by bjam issue, and my tests run and pass

Thanks for your help Steve.
