Bug#678033: clang++ --std=gnu++11 fails to compile <iostream>

[Sami Liedes]

Package: clang
Version: 3.1-5
Severity: normal

I assume clang++ tries to support the --std=gnu+11 option. Compiling a
hello world program with it fails:

------------------------------------------------------------
$ cat test.cpp
#include <iostream>

int main() {
    std::cout << "Hello, world!" << std::endl;
}
$ clang++ test.cpp -o test -std=gnu++11
