Hi All, LLVM now includes a C++ standard library, written by Howard Hinnant. You can read about it here: http://blog.llvm.org/2010/05/new-libc-c-standard-library.html Or get the code here: svn co http://llvm.org/svn/llvm-project/libcxx/trunk libcxx If you have questions or comments, please direct them to one of the clang mailing lists. Thanks! -Chris
