What happens with the Intel compiler if you don't specify -std=c++0x?
The regression tests are passing for Intel on Linux, but it doesn't
look like any of them specify -std=c++0x

What version of the Intel compiler are you using?

What version of Boost are you using?

That one of the problems of the && assert idiom. Now that we've got
BOOST_ASSERT_MSG, it can be used to quiet those warnings. I'll take
care of that.
