No, it's msvc-8.0
Regression results aside, this doesn't compile:
typedef boost::mpl::string<'hell', 'o wo', 'rld!'> str;
std::cout << boost::mpl::at<str, boost::mpl::int_<0> >::value <<
std::cout << str::c_str << std::endl;
Again, I simply copied char.hpp, char_fwd.hpp, and string.hpp into boost
It could be that it's because I'm not grabbing the entire boost tree
from svn but since I can replicate the problem with a basic program
that's using the same techniques you are, I really doubt that.
Looking deeper, you need to change:
#if BOOST_WORKAROUND(BOOST_MSVC, == 1310)
#if BOOST_WORKAROUND(BOOST_MSVC, <= 1400)
Alternatively, you could just keep telling me it's working and I'll go
away. I'm not loaded with a lot of spare time either.
