[boost] Many Boost.Test unit tests fail

Hi, Since today or yesterday, many regression tests fail. http://www.boost.org/development/tests/trunk/developer/summary.html I believe on platforms that are recently added, at last on platforms that were not present at December 17. 1) on clang/darwin, message ../boost/test/tools/assertion.hpp:278:21: error: no member named 'forward' in namespace 'std' 2) on clang/linux, message /usr/bin/ld: skipping incompatible /sierra/Sntools/extras/compilers/gcc-4.4.4/lib/libstdc++.so when searching for -lstdc++ We have these errors in Boost.Geometry but I also noticed them in many other libraries.
