4784,numeric/interval/hw_rounding for __amd64__,Jim Bell <jim@…>,Boris Gubenko,"Interval fails regression tests requiring numeric/interval/hw_rounding.hpp. It gives 
{{{
../boost/numeric/interval/hw_rounding.hpp:40:4: error: #error Boost.Numeric.Interval: Please specify rounding control mechanism.
}}}

My compiler defines __amd64__ (note the double underscores before and after).  How do I determine the hardware rounding control mechanism?

Here's [http://support.amd.com/us/Processor_TechDocs/24592.pdf the AMD64 manual (pdf)], but I don't understand things well enough to say which mechanism it uses.
