Hi,

Most of the nightly tests for Clang trunk with c++11 and libc++ are failing with this error message.

-bash-4.1$ "/scratch/kbelco/llvm_linux/build/Release+Asserts/bin/clang++" -c -x c++ -O0 -g -std=c++11 -stdlib=libc++ -fno-inline -Wall -pedantic -g -fPIC -std=c++11 -stdlib=libc++ -DBOOST_ALL_NO_LIB=1 -DBOOST_REGEX_DYN_LINK=1 -I"../boost" -o "/scratch/kbelco/boost/results/boost/bin.v2/libs/regex/build/clang-linux-trunk/debug/c_regex_traits.o" "../boost/libs/regex/build/../src/c_regex_traits.cpp"

Here's more detail about what clang is doing.

-bash-4.1$ "/scratch/kbelco/llvm_linux/build/Release+Asserts/bin/clang++" -### -c -x c++ -O0 -g -std=c++11 -stdlib=libc++ -fno-inline -Wall -pedantic -g -fPIC -std=c++11 -stdlib=libc++ -DBOOST_ALL_NO_LIB=1 -DBOOST_REGEX_DYN_LINK=1 -I"../boost" -o "/scratch/kbelco/boost/results/boost/bin.v2/libs/regex/build/clang-linux-trunk/debug/c_regex_traits.o" "../boost/libs/regex/build/../src/c_regex_traits.cpp"

Anyone come across this problem before, know how to fix it?
