I use long long and long double in the configuration of my integer arithmetic traits.  I'd like to guard those usages with boost macros to allow the code to compile on platforms that don't support long long and long double (replace with long and double respectively) but I can only find a BOOST_HAS_LONG_LONG macro (which is apparently not documented) and not a corresponding BOOST_HAS_LONG_DOUBLE.  Is there some other macro I can use to detect BOOST_HAS_LONG_DOUBLE or a typedef I can use that is already set to long double if available and double otherwise?

Thanks,
Luke
